A healthy banana bread mug made in the microwave in less than 3 minutes. This light and fluffy single-serve banana bread is the perfect way to enjoy banana bread without making an entire loaf. Vegan, gluten-free, oil-free, and refined sugar-free.



½ medium ripe banana (about 3 tablespoons mashed)
2 tablespoons unsweetened almond milk⠀
12 teaspoons of maple syrup (optional)⠀
2 teaspoons tahini (or any nut/seed butter)⠀
¼ teaspoon vanilla extract
¼ cup oat flour*⠀
½ teaspoon baking powder⠀
Pinch of sea salt⠀
Chopped dark chocolate


The batter can be made in a small bowl or directly in the mug for less clean up.

In a bowl or small mug, mash the banana. Mix in the almond milk, tahini, maple syrup (if using), and vanilla extract until smooth. Add in the oat flour, baking powder, and sea salt. Stir until just combined. If making in a separate bowl, transfer the batter to a small mug. Top with the chopped dark chocolate.

Place the mug the microwave for 2 minutes. The mug cake will rise significantly in the microwave then fall. You’ll know the mug cake is done when the bread starts to pull away from the edge of the mug. Let cool for 2-3 minutes before digging in.


  • Oat flour – oat flour makes this mug cake naturally gluten-free. You can make your own oat flour by grinding it in a blender or food processor. Make sure the texture is very fine. If you still see pieces of oats, keep going. Feel free to use another flour such as whole wheat, spelt or an all-purpose gluten-free blend. I do not recommend substituting almond or coconut flour in this recipe.
  • Tahini – any nut or seed butter would work in place of the tahini. You can also substitute melted coconut oil or avocado oil.
  • Lower sugar option – omit the maple syrup. If you’re using extremely ripe bananas you may find the banana bread is sweet enough without it. Otherwise, adjust to you’re liking
  • Add-ins – substitute chopped dark chocolate, chocolate chips, or forgo the chocolate all together. Other additions like walnuts, pecans, coconut flakes, berries, or a swirl of nut butter would be delicious.
