1 cup cooked, mashed butternut squash (or pumpkin)
4 eggs

1 cup stout beer
4 cups whole wheat flour
2 – 4 Tablespoons cocoa powder
2 teaspoons EACH: baking powder, baking soda, salt
1 teaspoon cinnamon

Instructions

Preheat the oven to 350 F. and spray 2 large loaf pans with cooking spray or brush with oil.
In a large mixing bowl, cream together the sugars and butter until fully mixed. Add in the peanut butter until fully incorporated, then the mashed banana and butternut, eggs and vanilla. Stir in the beer.
Sprinkle the dry ingredients over top and stir, folding from the bottom to make sure you get everything incorporated. Stop stirring as soon as it’s all mixed. Fold in the chocolate chips and/or nuts. Pour into the prepared pans.
Bake at 350 F. for 50 – 60 minutes or until a wooden pick inserted in the center comes out clean — or the internal temp is at or above 200 F.
