Instructions
Make Brownies:
Preheat oven to 350°F. Grease a 8″ square baking pan or line it with parchment with a little hanging over the edges, so it is easy to the brownies out of the pan.
In a measuring bowl, combine milk with vinegar and set aside for a few minutes to curdle.
In a mixing bowl, sift all purpose flour, baking soda, cocoa powder, espresso powder and salt. Add the sugar and mix well to combine.
Add oil and vanilla to the milk mixture and mix well.
Add the wet ingredients to the dry ingredients and combine until there are no more streaks of flour left. Gently stir in the chopped walnuts.
Pour the batter into the prepared baking pan and bake for 25~30 minutes or until a cake tester inserted into the center comes out with just a few crumbs.
Let the brownies cool in the pan completely before cutting into squares. Store in an airtight container in the fridge for up to 5 days.
Make Chocolate Frosting:
Melt butter. Stir in cocoa powder. Add confectioners sugar and milk, beat into spreading consistency. Stir in Vanilla.
Notes
Non-Vegan option: Use 1 cup of buttermilk instead of Milk+Vinegar mixture.
