Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

Pumpkin puree (unsweetened)
Eggs
Protein powder (vanilla or unflavored)
Oat flour or almond flour
Maple syrup or honey
Baking powder
Baking soda
Pumpkin pie spice
Cinnamon
Salt
Greek yogurt or unsweetened applesauce
Optional: chopped nuts, chocolate chips, or seeds

Directions

I preheat the oven to 350°F (175°C) and grease a loaf pan or line it with parchment paper.
In a large bowl, I whisk together the eggs, pumpkin puree, Greek yogurt (or applesauce), and maple syrup.
I stir in the protein powder, oat flour, baking powder, baking soda, pumpkin pie spice, cinnamon, and salt until just combined.
I fold in any add-ins like nuts or chocolate chips if using.
I pour the batter into the prepared loaf pan and smooth out the top.
I bake for 40–45 minutes, or until a toothpick inserted in the center comes out clean.
I let it cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.

Servings and timing

This recipe makes 8–10 slices. It takes about 10 minutes to prepare and 40–45 minutes to bake. I usually allow another 15–20 minutes for it to cool before slicing.

Variations

I sometimes use almond flour for a grain-free version with a slightly nuttier flavor.
For extra protein, I add a scoop of collagen powder or flaxseed meal.
I mix in raisins, pumpkin seeds, or walnuts for more texture.
If I want a lower-sugar version, I reduce the maple syrup and use stevia or monk fruit sweetener.

storage/reheating

I store the loaf in an airtight container at room temperature for up to 2 days or in the fridge for up to 5 days. To freeze, I slice it and wrap each piece individually before placing them in a freezer bag. To reheat, I microwave a slice for 15–20 seconds or toast it lightly. Pumpkin Spice Protein Loaf

FAQs

What kind of protein powder works best?

I usually use a whey or plant-based protein powder with a neutral or vanilla flavor. I avoid powders with a chalky texture or overpowering flavor.

Can I make this loaf dairy free?

Yes, I use unsweetened applesauce or a dairy-free yogurt alternative in place of Greek yogurt to make it dairy free.

Is this loaf sweet enough for dessert?

It’s lightly sweetened, so it works better as a breakfast or snack loaf. If I want a dessert-like version, I add a bit more maple syrup or a handful of chocolate chips.

Can I use canned pumpkin pie filling?

No, I stick with pure pumpkin puree to control the sweetness and spice levels. Pumpkin pie filling already contains added sugar and spices.

Why did my loaf turn out dry?

This loaf can dry out if overbaked or if too much protein powder is used. I always measure ingredients carefully and check doneness around the 40-minute mark.

Conclusion

Pumpkin spice protein loaf is my favorite way to enjoy fall flavors while keeping things light and nourishing. It’s easy to make, packed with good-for-me ingredients, and endlessly versatile. Whether I’m slicing it for a busy morning or enjoying it as an afternoon snack, it always hits the spot with its cozy spice and satisfying texture.
