Key Ingredients for this Cinnamon Roll Bun Bake

This cinnamon roll bun bake gets its bakery-inspired flavor from a simple batter, buttery cinnamon swirls, and a sweet finishing drizzle. Each ingredient plays a part in creating those golden tops and soft centers. Here’s what you’ll need to bring it all together!

• Greek Yogurt: Thick Greek yogurt adds moisture and protein to the batter while helping create that tender texture. Save the topping portion for serving—the cool, creamy yogurt is so good against the warm buns.
• Egg: The whole egg helps bind the batter and gives the buns structure as they bake. The yolk also adds a little richness to the base.
• Liquid Egg Whites: These add extra protein and help the batter set without adding another whole egg. They’re part of what makes this high protein bun bake such a satisfying breakfast.
• Unbleached All Purpose Flour: Flour provides the structure needed to turn your thick batter into scoopable buns. It gives the centers enough substance to hold those delicious cinnamon butter pockets.
• Vanilla Milkshake Protein Powder: Vanilla protein powder boosts the protein while adding sweetness and flavor to the batter. It pairs perfectly with the warm spice and powdered sugar glaze.
• Baking Powder: This helps the scoops rise in the oven, giving your Greek yogurt bun bake a lighter texture. A little lift makes all the difference!
• Baking Soda: Baking soda reacts with the acidity in the yogurt to help the batter rise. It works alongside the baking powder to create those fluffy centers.
• Unsalted Butter: Softened butter is the base of your cinnamon swirl. It mixes into a pipeable paste that melts into the buns as they bake, adding richness right where you want it.
• Zero Calorie Sweetener Blend: This sweetens the cinnamon butter so the filling has that familiar dessert-like flavor. Mixing it thoroughly with the softened butter helps distribute the sweetness.
• Ground Cinnamon: The star of this cinnamon bun bake! It brings warmth to the butter mixture, with an extra sprinkle over the yogurt to finish each serving.
• Organic Powdered Sugar: Powdered sugar creates a smooth, sweet glaze with very little effort. That drizzle over the golden buns is what ties the cinnamon-roll-inspired flavors together.
• Organic Nonfat Milk: A small splash loosens the powdered sugar into a pourable glaze. You’re looking for a consistency that drizzles easily while still leaving visible ribbons over the top.

Substitution Options

Want to make this cinnamon roll bun bake with what you already have? There’s some flexibility with the dairy, filling, and glaze ingredients. The batter needs a little more care because changing the flour or protein powder can affect how it bakes. These are suggested alternatives, with texture and sweetness differences to keep in mind.

• Greek Yogurt: Plain low-fat or full-fat Greek yogurt can replace the nonfat version. Choose a thick consistency so the batter stays scoopable, and remember that the nutrition will change.
• Vanilla Milkshake Protein Powder: Another vanilla protein powder is an option, but different blends absorb moisture differently. A whey-and-casein blend is closer to the original than a pure whey isolate or plant-based powder, though results can still vary. Avoid assuming every powder will produce the same texture.
• Unbleached All Purpose Flour: Regular all-purpose flour is the closest substitute. Whole wheat, gluten-free, almond, and coconut flours behave differently, so I wouldn’t recommend a direct swap without testing.
• Unsalted Butter: Salted butter can work in the cinnamon swirl; consider reducing the pinch of salt in the batter. A stick-style plant-based butter is another option for the filling, though the rest of the recipe still contains dairy.
• Zero Calorie Sweetener Blend: Granulated sugar or light brown sugar can sweeten the filling instead. Check your sweetener’s substitution guidance rather than assuming equal weights will have equal sweetness. Brown sugar would also bring a little molasses flavor to your cinnamon roll breakfast bake.
• Organic Powdered Sugar: Conventional powdered sugar works just as well for the glaze. A powdered sugar substitute is another possibility, but its sweetness, texture, and cooling aftertaste can vary.
• Organic Nonfat Milk: Any dairy milk can thin the glaze. Unsweetened almond or soy milk can also work here; add it gradually until the mixture is easy to drizzle.
• Greek Yogurt Topping: Vanilla Greek yogurt is a delicious alternative if you prefer a sweeter finish. Thick plain skyr is another option for serving alongside this high protein bun bake.

For the closest result, keep the egg, egg whites, and leaveners as written. Start with a simple topping or glaze swap if you want to personalize the recipe. Any ingredient changes can affect the final macros, including the protein per serving.

Equipment and Tools

You don’t need any fancy equipment to make this cinnamon roll bun bake. A bowl, whisk, and spatula handle the batter, while an ice cream scoop makes portioning easy. A piping bag gives you those cinnamon butter spirals with very little fuss. Here’s what to grab before you start.

• Mixing Bowl: Choose a bowl with enough room to whisk the wet ingredients and fold in the dry without flour spilling over the sides.
• Whisk: Useful for combining the Greek yogurt, egg, and egg whites into a smooth mixture before adding your dry ingredients.
• Rubber Spatula: Perfect for mixing the thick batter and scraping down the bowl. It also helps transfer the cinnamon butter into your piping bag.
• Small Bowls: Use one for the cinnamon butter and another for the powdered sugar glaze. Keeping them separate makes assembly easier.
• Small Spoon: Handy for mixing the filling and glaze, then drizzling the finished glaze over your cinnamon bun bake.
• Oven-Safe Baking Dish: Choose a dish that comfortably holds six scoops with a little room for them to expand. A much larger dish may let the batter spread more and bake faster.
• Ice Cream Scoop: Makes it easy to create evenly sized buns so they bake at a similar rate. A spring-release scoop is especially helpful with the thick batter.
• Piping Bag: Holds the cinnamon butter for piping spirals and adding filling to the centers. A sturdy food-safe zip-top bag with a corner snipped off can also work.
• Kitchen Scissors: Use these to snip a small opening in the piping bag. Start small—you can always widen it if the filling is difficult to squeeze out.
• Measuring Scale: The easiest way to measure your flour, protein powder, yogurt, and other ingredients accurately. It also helps you keep the batter yogurt separate from the serving portion.
• Measuring Spoons: Useful for measuring the cinnamon, baking powder, and baking soda.
• Toaster Oven or Traditional Oven: Either can bake this high protein bun bake. Preheat before baking and check for golden tops and a cooked center around the suggested time.
• Toothpick: Helps check that the buns are cooked through. Test the batter portion so the buttery filling doesn’t confuse the result.
• Oven Mitts: Keep these nearby for safely removing the hot baking dish.

Once everything is ready, the batter and swirls come together quickly. Keep your glaze bowl handy while the buns bake, and you’ll be ready for that finishing drizzle!

How to Make Your Cinnamon Roll Bun Bake

This cinnamon roll bun bake gives you those cozy flavors with a simple mix-and-scoop method. The batter comes together in one bowl, and there’s no kneading or rising involved. You’ll mix the cinnamon butter separately, then pipe it over the buns for those pretty spirals. A quick powdered sugar glaze finishes everything off once the bake has cooled slightly.

Mix Your Wet Ingredients

Preheat your oven to 350°F. In a mixing bowl, add 226g Greek yogurt, your whole egg, and the liquid egg whites.

Whisk until smooth and evenly combined. Keep the remaining 170g yogurt set aside for topping your servings later.

Add Your Dry Ingredients

Add the flour, vanilla protein powder, salt, baking powder, and baking soda directly over the wet mixture. Gently stir until incorporated and you have a thick, cake batter-like consistency.

You want the batter thick enough to scoop into mounds. Stop mixing once everything is combined to help keep your Greek yogurt bun bake tender.

Make the Cinnamon Butter Swirl

In a small bowl, mix the softened butter, sweetener, and cinnamon into a smooth, pipeable paste. The butter should be soft enough to stir easily without being melted and runny.

Transfer the mixture to a piping bag and snip a small opening at the tip.

Scoop and Swirl

Lightly coat your baking dish with olive oil spray. Use an ice cream scoop to portion the batter into six buns.

Pipe a cinnamon butter spiral over each scoop. Gently push the piping bag’s tip into the centers and squeeze any remaining mixture inside for a little extra filling in the middle.

Bake Until Golden

Bake for about 25 minutes, until the tops are golden and the buns are cooked through. Insert a toothpick into the batter portion rather than directly through a cinnamon butter pocket to check that it comes out clean.

Set the dish aside to cool slightly before glazing.

Add the Glaze

Mix the powdered sugar with the milk in a small bowl until smooth. Drizzle over your cinnamon bun bake, letting it settle into those swirls and little gaps.

Ways to Enjoy

Serve warm with the reserved Greek yogurt, dividing the topping between your servings. Finish with a sprinkle of cinnamon for a little extra warmth.

The creamy yogurt, sweet glaze, and tender centers make such a delicious combination. Grab a coffee and enjoy your cinnamon roll breakfast bake while it’s still warm!

Tips and Tricks

A few simple details can make all the difference in your cinnamon roll bun bake. From getting the batter consistency right to piping those buttery spirals, these tips will help you get golden tops and tender centers.

• Use Thick Greek Yogurt: A thick yogurt helps the batter hold its shape when scooped. A thinner consistency can cause the buns to spread more in the baking dish.
• Keep the Yogurt Portions Separate: The batter uses 226g of Greek yogurt, while the remaining 170g is for serving. Set the topping portion aside before mixing so it doesn’t accidentally end up in your batter!
• Choose Your Protein Powder Carefully: Different protein powders absorb moisture differently, which can change the texture of this high protein bun bake. Refer to the substitution notes before switching brands or blends.
• Avoid Overmixing: Fold in your dry ingredients just until combined. You want a thick, scoopable batter without working it more than necessary.
• Soften Rather Than Melt: Your butter should be soft enough to mix into a smooth cinnamon paste. Melted butter makes the mixture runnier and harder to pipe into neat spirals.
• Start with a Small Opening: Snip just a little off the piping bag’s tip, then widen it if needed. This gives you more control when decorating each scoop.
• Save Some Filling for the Centers: Pipe the tops first, then gently squeeze any remaining cinnamon butter into the middle of each bun. Those little pockets are worth the extra step!
• Check the Batter Portion: When testing your cinnamon bun bake with a toothpick, avoid pushing it directly through a butter pocket. Look for a cooked center rather than relying only on the color of the tops.
• Glaze After a Short Rest: Let the bake cool slightly before drizzling. The glaze will stay more visible instead of immediately melting into the hot buns.

Serve your Greek yogurt bun bake warm and add the yogurt topping just before digging in. That combination of creamy topping, sweet glaze, and buttery filling is the best part!

Storage Instructions

Have some cinnamon roll bun bake left for another morning? Store the buns and toppings separately when possible to make reheating easier. A little care helps keep the centers tender without letting the surface become soggy.

• Refrigeration: Store leftover buns in an airtight container in the refrigerator for up to 3–4 days. Refrigerate within two hours of baking rather than leaving the dish out for the afternoon.
• Separate the Toppings: Keep the serving yogurt covered in the refrigerator and add it after reheating. If you haven’t glazed the entire cinnamon roll breakfast bake, refrigerate the milk-based glaze separately, too.
• Store Already-Topped Buns Carefully: If you’ve already added the yogurt, refrigerate those portions promptly in a sealed container. Enjoy them chilled or remove as much of the yogurt as practical before warming the buns.
• Reheat Gently: Warm an individual portion in the microwave in short intervals, checking between each one. Cover loosely with a microwave-safe lid to help retain moisture, and avoid heating longer than needed.
• Freezing Option: For longer storage, freeze cooled, unglazed buns without the yogurt topping. Wrap individual portions tightly and place in a freezer-safe container for up to two months for best quality; the texture may change slightly after thawing.
• Thaw Before Warming: Thaw frozen portions in the refrigerator overnight, then gently reheat. Add fresh glaze, yogurt, and a sprinkle of cinnamon when serving.

This high protein bun bake makes a delicious breakfast to come back to. Reheat only the portion you plan to eat and keep the rest refrigerated. Finish with your creamy topping, grab a coffee, and enjoy!
