1 cup oat flour, ¾ cup unflavored whey protein concentrate, 1 teaspoon baking soda, ½ teaspoon baking powder, 1 ½ teaspoons pumpkin spice
Pour into prepared loaf pan.
Bake for 35-40 minutes or until a toothpick inserted comes out clean.
Let cool in pan for 10 minutes, then remove from pan and let cool completely on a wire rack before slicing.
Notes
I recommend whey protein concentrate for baking (instead of whey protein isolate) because the texture will be better. I used unflavored here, but a lightly flavored vanilla will also work.This recipe was developed for whey protein powder, and I do not recommend subbing other types of protein powder.I used light olive oil here, but any kind of oil for baking will work.I used (gluten free) oat flour here, and I do not recommend substituting with all-purpose flour. Doing so would give a much more dense, tough pumpkin bread. Other gluten-free flours (without added gums) should also work here.I used coconut sugar here because it is unprocessed and low glycemic. Substituting regular sugar would be fine here. Sugar substitutes like granulated erythritol would work texturally, but you'll notice a big difference in taste.RECIPE VARIATIONS:Pumpkin Banana Bread: Turn this into protein pumpkin banana bread by using ½ cup pumpkin and 1 ½ mashed bananas (in place of the 1 cup pumpkin in this recipe).Chocolate Chip Pumpkin Bread: Add ¾ cup sugar free chocolate chips to this pumpkin protein bread for a delicious and healthy chocolate chip protein pumpkin bread.Pumpkin Zucchini Bread: Turn this into protein pumpkin zucchini bread by using ½ cup pumpkin and 1 small zucchini, grated (in place of the 1 cup pumpkin in this recipe).Cranberry Pecan Pumpkin Bread: Add ⅓ cup dried cranberries and ⅓ cup chopped pecans for a delicious fall treat!Pumpkin Muffins: Bake the batter in a muffin pan for protein pumpkin muffins. Check on them after 20 minutes (I'll update this with an exact time ASAP!).PRO TIP:Don't overbake! The bake time for this healthy protein pumpkin bread is a bit less than our protein banana bread and protein zucchini bread because the pumpkin is more condensed (has less moisture) than the banana or zucchini.STORAGE:Store in an airtight container in the refrigerator. To freeze, wrap in plastic wrap (whole or as individual slices) and place in a freezer ziploc bag.
