  • 1/2 cup dark chocolate chips
  • 1/4 T. unsalted butter
  • 2 T. strongly brewed coffee


Preheat oven to 350 degrees F. Grease and flour 10-inch bundt pan. Set aside.
Using electric mixer, mix sugar, eggs and oil on low until combined, about 1 to 2 minutes. Mix in zucchini and yogurt. Add cocoa and coffee.

In separate bowl, whisk together salt, baking powder, all-purpose flour and whole-wheat flour. Gradually add dry ingredients to wet ingredients, and mix just until combined. Slowly mix in water. Stir in chocolate chips and walnuts.

Pour batter into prepared bundt pan. Bake for about 40 to 45 minutes, or until toothpick inserted in center comes out clean. Cool cake for 15 minutes in pan. Remove from pan and transfer to plate or cooling rack to cool completely.

In microwave-safe dish, combine dark-chocolate chips and butter. Microwave on high in 20 second intervals, and stir between each interval. Once chocolate and butter are melted, stir in warm coffee.

Pour glaze over cake, and allow it to cool and set before slicing and serving.
