Vanilla protein powder: Use a high-quality vegan protein powder to boost the protein content and make this mug cake more filling for breakfast.
Cinnamon: Cinnamon is the key spice that transforms this from a simple banana cake into a cozy banana bread mug cake.
Baking powder: This helps the mug cake rise and creates a soft, fluffy texture.
Vanilla: A splash of pure vanilla extract adds warmth and depth to the banana bread flavor.
Maple syrup: Naturally sweetened with pure maple syrup for a touch of wholesome sweetness.
Plant-based milk: Use your favorite dairy-free milk to bring the batter together and keep the mug cake moist.
Toppings: Finish with a dollop of plant-based yogurt and a sprinkle of chopped pecans for extra creaminess, texture, and flavor.

Frequently Asked Questions

You can, but this mug cake is best enjoyed fresh while it’s warm and soft. If you’d like to make it ahead, cover the mug with plastic wrap and store it in the refrigerator for up to one day. When you’re ready to enjoy it, reheat in the microwave until warmed through.

Not really. As long as it is microwavable. The mug cake does not rise much so you don’t have to leave too much space.
The Instructions
Step one: Spray a large, microwavable coffee mug with a coconut oil spray or grease with coconut oil or vegan butter.
Step two: Mash the banana at the bottom of the mug with a fork or small whisk.

Step three: Add the remaining ingredients, including oat flour, oats, protein powder, milk, maple syrup, vanilla, baking powder, and cinnamon. Mix well, scrape batter from sides, and spread into an even layer.

Step four: Microwave for 2 minutes. Allow the mug to sit for 2-4 minutes to slightly cool. And then top with a dollop of plant-based yogurt and pecans or your favorite toppings and enjoy!

Storage
I recommend enjoying this mug cake warm straight out of the microwave. It does not keep well as leftovers.
