  • Preheat oven to 180C / 350F . In a large mixing bowl, mix together oat flour, sugar, cocoa powder, baking powder and instant coffee powder. Mix until everything is well incorporated.
  • Add in the plant milk, applesauce, cashew butter and vanilla extract. Mix well. Pour batter into an oiled 8x8 baking pan. You can also line pan with parchment paper instead.
  • Bake for 18-22 minutes, or until a toothpick comes out fairly clean from the center. It is okay to have a few crumbs left on it as brownies will continue to cook out of the oven.
  • Let it cool completely, before slicing and serving.


*Coconut sugar - can be substituted with other granulated sweeteners like brown and white sugar or sugar-free substitutes.
**Cashew butter - can be substituted with other kinds of nut butter like peanut or hazelnut. You can even make this nut-free by using tahini, pumpkin seed butter or sunflower seed butter instead. Just keep in mind that it might affect the overall taste of your brownies. 
Helpful tips 
  • If you prefer your brownies to be fudgy, bake them for 15-18 minutes or until the center is just set.
  • It is really important to let your oat flour brownies cool down to room temperature before slicing! It allows times for it to develop its flavors and also prevent them from crumbling. Slice them with a plastic knife instead of bread knife or other serrated knifes for a cleaner cut.
Storing - Brownies will stay good at room temperature for 3-4 days, depending on the climate. To prevent them from drying out, it is recommended to leave them uncut before serving.

Brownie slices can also be stored in the fridge for up to a week, either in an airtight container or wrapped with plastic wrap. They are also freezable too, and you can either freeze it whole or slices of it. Wrap them in a layer of plastic wrap and they can now be stored in the freezer for up to 3 months.

Reheating - To reheat frozen brownies, let them defrost in the fridge overnight or on countertop for a few hours. Or, you can heat them up in the microwave to speed up the process!
