Step 1

Preheat oven to 350°F. Line an 8 inch x 8 inch baking pan with parchment paper.

Step 2

Add flour, cocoa powder, sugar, baking soda, and salt directly into baking pan. Whisk together until evenly combined.

Step 3

Make two small wells and 1 large well in the dry ingredients. Add vanilla to one small well and vinegar to the other small well. Add oil to the large well. Pour the water over the top and whisk everything until batter becomes smooth and evenly combined.

Step 4

Place cake into oven and bake for about 35 minutes or until a toothpick inserted comes out clean. Let cake cool completely before frosting. You can top with your favorite chocolate frosting, powdered sugar, or chocolate ganache.

Step 5

To make chocolate ganache: Add chopped chocolate to a medium bowl. Bring heavy cream to a simmer on the stove. Pour heated heavy cream over chopped chocolate and immediately start to mix until the chocolate is completely melted and smooth. Let chocolate ganache cool at room temperature or in the fridge until it becomes firm enough for frosting the cake.
