Step 1

Preheat oven to 350°F (177°C). Line an 8 x 4 inch loaf pan with parchment paper.

Step 2

Add chocolate chips and mashed bananas to a large microwave-safe bowl. Heat in the microwave in 15-30 second intervals, stirring in between with a spatula, until chocolate is completely melted and smooth. Switch to a whisk and mix until the batter becomes uniform in color. You can also melt the chocolate on the stove using the double boiler method.

Step 3

Stir in oat flour and mix with whisk until oat flour is fully and evenly incorporated into the batter. If adding any mix-ins, like additional chocolate chips, stir them in now.

Step 4

Pour batter into the prepared pan. Bake for about 30 minutes or until the surface of the brownies looks mostly cooked. The brownies will not look fully set because they are supposed to be very fudgy. Let the brownies cool before cutting and serving. Store any uneaten brownies in the fridge and reheat before eating.
