Preheat oven to 350°F (175°C). Grease two 8-inch round cake pans and line the bottoms with parchment paper.
Add the drained beets to a food processor or blender and puree until completely smooth with no chunks remaining. Set aside.

In a large bowl, whisk together flour, cocoa powder, granulated sugar, brown sugar, baking soda, baking powder, and salt until well combined.
1¾ cups all-purpose flour, ¾ cup Dutch-process cocoa powder, 1½ cups granulated sugar, ½ cup dark brown sugar, 1½ teaspoons baking soda, 1 teaspoon baking powder, 1 teaspoon salt
In a separate bowl, whisk the eggs. Add buttermilk, vegetable oil, vanilla extract, and the beet puree. Whisk until smooth and well combined.
2 large eggs, 1 cup buttermilk, ¾ cup vegetable oil, 2 teaspoons vanilla extract
Add the wet ingredients to the dry ingredients and mix just until combined.
Stir in the melted chocolate until incorporated.
4 oz dark chocolate
Slowly add the hot coffee and mix until smooth. The batter will be thin - this is perfect!
¾ cup hot coffee
Divide the batter evenly between the prepared pans.
Bake for 30 minutes, until a toothpick inserted in the center comes out with moist crumbs (not wet batter, but not completely dry - we want fudgy!).
Cool cakes in the pans for 15 minutes, then turn out onto wire racks to cool completely.
