Step‑by‑Step Instructions for Protein Cinnamon Roll Mug Cake
Step 1: Combine Dry Ingredients
In a microwave-safe mug, start by mixing together your protein powder, oat flour, baking powder, ground cinnamon, and a pinch of salt. This dry mixture forms the foundation of your Protein Cinnamon Roll Mug Cake, so ensure all components are well combined. Use a fork or a small whisk for an even blend.
Step 2: Incorporate Wet Ingredients
Next, add the large egg, unsweetened almond milk, maple syrup, and vanilla extract to the mug. Stir vigorously with a fork until the batter is smooth and all wet ingredients are fully integrated. The mixture should be creamy and homogenous, devoid of any lumps, indicating it’s ready for the next step.
Step 3: Prepare Cinnamon Swirl
In a separate small bowl, combine melted coconut oil, brown sugar, and additional ground cinnamon until it’s a thick paste. This swirl mixture is essential for infusing your Protein Cinnamon Roll Mug Cake with that classic cinnamon roll flavor. Ensure it’s well mixed and ready to elevate your cake’s flavor profile.
Step 4: Add and Swirl Mixture
Spoon the cinnamon swirl mixture gently on top of your batter in the mug. Using a toothpick or a knife, carefully swirl it into the batter. Be mindful to maintain some separation; the goal is to achieve a delightful marbled effect, creating that iconic gooey cinnamon swirl you love.
Step 5: Cook Mug Cake
Place your mug in the microwave and cook on high for about 60 to 90 seconds, keeping a close eye on it. The cake should rise and have its center set but still look slightly moist—this ensures the warm, gooey texture reminiscent of cinnamon rolls. Avoid overcooking to maintain the soft consistency.
Step 6: Prepare Frosting
While the cake is cooling slightly, prepare the frosting by mixing Greek yogurt, softened cream cheese, and maple syrup or powdered sugar in a small bowl. Blend until the frosting is smooth and creamy. This delightful topping will perfectly complement the warmth of your Protein Cinnamon Roll Mug Cake.
Step 7: Frost and Serve
Finally, once your mug cake has cooled for a minute, drizzle or spread the creamy frosting generously over the top. The warm cake will allow the frosting to melt slightly, creating a luscious topping. Dig in and enjoy your Protein Cinnamon Roll Mug Cake while it’s warm and fresh!
