Instructions
- Prepare the Dry Mix:
- Add protein powder oat flour baking powder cinnamon and salt to a microwave safe mug at least twelve ounces in size. Mix thoroughly with a fork to combine and aerate everything.
- Mix in the Wet Ingredients:
- Crack a large egg into the mug and pour in almond milk maple syrup and vanilla extract. Stir well to blend until no dry spots remain. Be sure to scrape the sides and bottom so all the flour is incorporated.
- Make the Cinnamon Swirl:
- In a small bowl combine coconut oil brown sugar and a little cinnamon. Stir until the sugar dissolves and you get a syrupy cinnamon paste.
- Swirl the Batter:
- Drop small spoonfuls of the cinnamon swirl mixture on top of the mug cake batter. Gently drag a toothpick or butter knife through to create pretty swirls but do not over mix. This step creates those gooey cinnamon layers.
- Microwave to Perfection:
- Place the mug in the center of the microwave and cook on high for sixty to ninety seconds. The cake should rise and look set in the center but still a little moist. If your microwave is powerful check after sixty seconds to avoid overcooking.
- Make the Frosting:
- While the mug cake cools for a minute mix Greek yogurt cream cheese and a little maple syrup or powdered sugar in a bowl until smooth and fluffy.
- Finish and Serve:
- Dollop or drizzle the frosting over the warm mug cake. Enjoy straight from the mug while it is still soft and the cinnamon aroma is strongest.
Save Brown sugar is my secret favorite in this recipe because it melts into those little cinnamon pockets just like the center of a real cinnamon roll. The first time I shared this mug cake with my daughter we both fought over the last cinnamon swirl at the bottom.
Storage Tips
This mug cake is best eaten warm and fresh for maximum softness and that classic ooey gooey texture. If you need to make it ahead you can combine the dry ingredients the night before and add the wet just before microwaving. Leftovers can be stored covered in the fridge for up to one day and reheated gently but the texture is never quite the same as when it is fresh out of the microwave.
Ingredient Substitutions
Feel free to swap almond flour for oat flour for a gluten free version or use certified gluten free oats if you are sensitive. Any plant based milk or cow milk will work just make sure it is unsweetened if you want to control the sweetness. Replace eggs with a flaxseed egg or your favorite vegan substitute for an egg free treat. Plant based yogurt and cream cheese work nicely in the frosting for dairy free diets.
Serving Suggestions
Dress up your mug cake with a sprinkle of toasted pecans or walnuts for crunch. Sometimes I will add a small handful of mini chocolate chips to the batter if I am in the mood for a chocolate cinnamon mashup. Serve alongside hot coffee or a frosty protein shake for a balanced breakfast.
Cultural and Historical Context
Mug cakes surged in popularity as the demand for single serving treats skyrocketed in recent years especially among college students and busy professionals. This recipe borrows the cinnamon sugar swirl from classic American cinnamon rolls and reimagines it in a speedy protein forward format that fits modern tastes and lifestyles.
Seasonal Adaptations
In autumn swap the cinnamon for pumpkin spice and stir a tablespoon of pumpkin puree into the batter. In summer try fresh blueberries or diced apples for a fruity twist. For winter richness add a pinch of nutmeg or a splash of orange zest.
