Ingredients
- Vanilla protein powder: adds a rich flavor and boosts protein content. Choose a powder with a mild vanilla taste for best results
- Oat flour: brings a gentle texture and wholesome fiber. Look for finely ground, fresh oat flour to avoid bitterness
- Baking powder: helps the cake rise for a light, fluffy texture
- Ground cinnamon: delivers warm spice and classic cinnamon roll flavor
- Granulated sweetener: lets you control the sugar level while keeping it low calorie. Try monk fruit or erythritol for a natural choice
- Salt: intensifies flavors and balances the sweetness
- Milk: adds moisture and richness. Use dairy or your favorite plant-based milk for a dairy-free version
- Egg white: provides structure while keeping fat low
- Vanilla extract: adds depth and enhances the sweetness naturally
- Melted butter or coconut oil: lends a tender crumb and richness
- Brown sugar or coconut sugar: for the cinnamon swirl brings caramel notes and a touch of sweetness
- Light cream cheese: softens to create a luscious topping with a tangy bite
- Powdered sweetener or sugar: sweetens the cream cheese without graininess
Step-by-Step Instructions
- Sift and Mix Dry Ingredients:
- Combine vanilla protein powder, oat flour, baking powder, ground cinnamon, granulated sweetener, and a pinch of salt in a microwave-safe mug of at least 10 fluid ounces. Stir these dry components thoroughly to ensure even distribution of baking powder and cinnamon flavor throughout the batter.
- Add Wet Ingredients and Stir Smooth:
- Pour in the milk, egg white, and vanilla extract into the dry ingredients. Stir continuously with a spoon or small whisk until the batter becomes smooth and free of lumps. This step is key to avoid pockets of dry flour or powder in the final cake.
- Prepare the Cinnamon Swirl:
- In a small bowl, mix together melted butter, brown sugar, and ground cinnamon until the sugar dissolves and the mixture is uniform. This swirl adds rich caramel and spice notes that mimic a classic cinnamon roll.
- Create the Swirl Effect in the Batter:
- Drop small spoonfuls of the cinnamon swirl mixture evenly over the cake batter in the mug. Using a toothpick, skewer, or knife, gently swirl the cinnamon mixture through the batter in a marbled pattern without overmixing.
- Microwave the Cake:
- Place the mug in the microwave and cook on high power for 60 to 90 seconds. The cake should be just set with the center slightly moist but not wet. Watch carefully as microwave times vary and overcooking leads to a rubbery texture.
- Mix the Cream Cheese Topping:
- While the cake cools for a minute or two, combine softened cream cheese, milk, powdered sweetener, and vanilla extract in a small bowl. Beat until smooth, creamy, and spreadable with no lumps.
- Top and Serve Immediately:
- Spread the cream cheese frosting over the warm cake surface. Serve right away so the topping melts slightly into the cake, enhancing the cinnamon roll experience.
Save
The cinnamon swirl is my favorite part because it creates bursts of warm, sweet spice right in the middle of the cake. The cream cheese topping makes it feel so indulgent, like a little hug in a mug that I often make to brighten a rushed morning.
Storage tips
This mug cake is best enjoyed immediately while warm and fresh. Leftover cake can be refrigerated covered for up to one day, but the texture may firm up and the cream cheese topping should be reapplied after warming. Reheat gently in 15-second microwave bursts to avoid drying out the cake.
Ingredient substitutions
You can swap oat flour for almond flour if you need a gluten-free option but note the texture will be denser and less tender. Use a plant-based protein powder and non-dairy milk for a vegan-friendly version. Coconut sugar or date sugar works well in the cinnamon swirl if you want unrefined sweetness.
Serving suggestions
Enjoy this mug cake plain or topped with fresh berries for a pop of color and antioxidants. A small drizzle of sugar-free caramel or maple syrup on top elevates the indulgence without too many extra calories. Pair with a cup of black coffee or chai tea to complement cinnamon’s warm spices.
Cultural context
Cinnamon rolls have European roots, especially popular in Swedish and American baking traditions. This single-serving mug cake version captures the essence of the beloved pastry in a speedy and health-conscious way, fitting modern lifestyles while honoring classic flavors.
Pro Tips
- Make sure your mug is big enough to prevent any overflow during microwaving which can be messy
- Don’t skip swirling the cinnamon mixture gently to keep the beautiful marbled appearance and pockets of sweet cinnamon
- I learned the hard way: avoid microwaving too long or the protein powder texture becomes tough rather than tender
Recipe FAQs

Yes, oat flour adds a tender texture, but almond or whole wheat flour can be substituted for varied flavors and nutrition.
- → How do I prevent the mug cake from overflowing?
Use a microwave-safe mug with at least 10 fluid ounces capacity to give the batter room to rise without spilling over.
- → Can I make this without egg whites?
Egg whites help create structure and lightness; however, aquafaba or a flax egg can be alternatives for binding.
- → How is the cinnamon swirl mixture made?
Simply blend melted butter with brown sugar and ground cinnamon, then gently drop onto the batter and swirl with a toothpick for marbled flavor.
- → Is there a dairy-free option for the topping?
Yes, swap the cream cheese for a vegan version and use a plant-based milk to keep the topping smooth and creamy.
- → What’s the best way to check doneness?
