Preparation Phase & Tools to Use
To get started on your High-Protein Cinnamon Roll Mug Cake, first gather all your ingredients and tools: a microwave-safe mug (at least 10 fluid ounces) is essential, as it prevents overflow during cooking. Ensure you have measuring cups and spoons for accurate portions, along with a mixing spoon to combine your ingredients thoroughly. If you have a toothpick or knife handy, this can help create the beautiful marbled effect of the cinnamon swirl within the cake.
You will begin by measuring out your dry ingredients, which include vanilla protein powder, oat flour, baking powder, ground cinnamon, granulated sweetener, and salt. Then, prep the wet ingredients: milk, egg white, and vanilla extract. The order in which you mix these ingredients is crucial for achieving a perfectly fluffy cake. Additionally, gather a small bowl for mixing the cinnamon swirl topping and another for preparing the cream cheese frosting. Having everything ready will ensure a smooth cooking process!

Ingredients
- 1/4 cup vanilla protein powder
- 2 tablespoons oat flour
- 1/4 teaspoon baking powder
- 1/4 teaspoon ground cinnamon
- 1 tablespoon granulated sweetener
- Pinch of salt
- 3 tablespoons milk
- 1 large egg white
- 1/2 teaspoon vanilla extract
- 1/2 tablespoon melted butter or coconut oil
- 1 tablespoon brown sugar or coconut sugar
- 1/2 teaspoon ground cinnamon
- 1 1/2 tablespoons light cream cheese, softened
- 1 teaspoon milk
- 1/2 tablespoon powdered sweetener or sugar
- 1/4 teaspoon vanilla extract
Instructions
Step 1: Combine the Dry Ingredients
In your microwave-safe mug, start by adding the vanilla protein powder, oat flour, baking powder, ground cinnamon, granulated sweetener, and a pinch of salt. Stir these dry ingredients together until thoroughly mixed. This ensures that each bite of your mug cake has a consistent flavor profile. The combination of protein powder and oat flour not only contributes to the cake’s structure but also enhances its nutritious value.
Step 2: Add the Wet Ingredients
Next, incorporate the milk, egg white, and vanilla extract into the dry mix. Use your spoon to stir continuously until you achieve a smooth batter without any lumps. This step is crucial, as a well-mixed batter will rise better and be fluffier. Be careful not to overmix, as that can lead to a denser texture. Aim for a batter that is neither too runny nor too thick, striking the right balance is key to a successful mug cake!
Step 3: Create the Cinnamon Swirl
In a separate small bowl, combine the melted butter, brown sugar (or coconut sugar), and ground cinnamon. Mix until all the sugar is incorporated into the butter. Drop spoonfuls of this fragrant mixture onto your cake batter. To create the signature marbled look, take a toothpick or a small knife and gently swirl through the batter, being careful not to mix it completely. This will give you those beautiful streaks of cinnamon that mimic traditional cinnamon rolls.
Step 4: Microwave Your Mug Cake
It’s time to cook! Place the mug in your microwave and cook on high power for about 60 to 90 seconds. Keep an eye on it, as microwaves vary in strength and timing. You want the cake to be set but still slightly moist in the center. Overcooking can lead to dry results, so it’s better to check earlier than later. Once done, take it out and allow it to cool for a minute or so; the cake will continue to cook slightly as it cools.
Step 5: Prepare the Cream Cheese Topping
While the cake is cooling, you can prepare the delicious cream cheese frosting. In a clean bowl, mix the softened light cream cheese, a teaspoon of milk, powdered sweetener, and remaining vanilla extract. Beat these together until the mixture reaches a smooth, spreadable consistency. This creamy topping adds richness to your mug cake and elevates it to a dessert classic!
Step 6: Serve and Enjoy!
Once your mug cake has cooled just enough, generously spoon the cream cheese frosting on top while it’s still warm. The warmth of the cake will melt the frosting slightly, creating a delectable layer that perfectly complements the spiced cake beneath. Serve immediately for the best experience!
