   Place beets in a pot with water to cover. Bring to a boil and cook for 30 minutes. Remove skin and puree beets in a blender or food processor.

   Preheat the oven to 375 degrees F (190 degrees C). Butter a 9x13-inch baking pan.

   Melt butter in a saucepan over low heat. Add unsweetened chocolate and stir until melted. Set aside to cool.
4. 4
   Combine all-purpose flour, whole wheat flour, baking soda, and salt in a small bowl.
5. 5
   Beat sugar and eggs together in a large bowl using an electric mixer until creamy. Add the melted chocolate, beets, and vanilla extract. Beat until combined.
6. 6
   Stir the flour mixture and chocolate chips into the beet mixture just until combined. Pour batter into the prepared pan.
7. 7
   Bake in the preheated oven until a fork inserted into the center comes out clean, about 40 minutes.
