Equipment

Coffee mug microwave-safe
Fork
Scale/measuring cups
Measuring spoons

Ingredients

1 tablespoon (14 g) unsalted butter
2 tablespoons (25 g) brown sugar light or dark, packed
¼ teaspoon vanilla extract
1 tablespoon (14.79 ml) Lifeway Lowfat Plain Kefir or buttermilk
½ medium (55 g) banana overripe
1 pinch ground cinnamon optional
1 pinch salt
¼ teaspoon baking soda
3 tablespoons (23 g) all-purpose flour
1-2 tablespoons optional mix-ins chocolate chips or blueberries

Instructions

Melt the butter in a coffee mug in the microwave.
1 tablespoon unsalted butter
Use a fork to mix in the brown sugar, vanilla extract, and kefir really well.
2 tablespoons brown sugar, ¼ teaspoon vanilla extract, 1 tablespoon Lifeway Lowfat Plain Kefir
Add the overripe banana and mash it into the wet ingredients with the fork.
½ medium banana
Stir in the cinnamon, salt, and baking soda (the baking soda should fizz a bit).
1 pinch ground cinnamon, 1 pinch salt, ¼ teaspoon baking soda
Mix in the flour so that all dry streaks are incorporated (scrape the sides of the mug if needed). Be careful not to over-mix.
3 tablespoons all-purpose flour
Optional: add mix-ins like chocolate chips or blueberries!
Microwave the banana bread in the mug for 30 seconds. Rotate the mug and continue microwaving in 10-second intervals until the top looks baked.
Let it cool for a few minutes so you don't burn your mouth. Enjoy!
