Cutting the sugar down and subbing for whole wheat flour are two automatic adjustments I normally make when baking up a healthier treat. And it still turns out delicious!
Preheat your oven to 350 degrees. Lightly grease a loaf pan.
In a large bowl, mix pumpkin, yogurt, eggs, peanut butter and vanilla with a whist. Whisk in the sugar, spice, cocoa, baking soda and flour until evenly mixed.
Pour batter into prepared pan and smooth so that it is even. Bake for 40 – 45 minutes or until middle is set (this is a very dense bread and you will likely always have a few crumbles with the tooth pick test).
