(or 1 tsp cinnamon + ¼ tsp nutmeg + ¼ tsp ginger + pinch cloves)
Wet Ingredients
- 1 cup pumpkin purée (not pumpkin pie filling)
- 2 large eggs
- ½ cup Greek yogurt
- ⅓ cup maple syrup or honey
- 2 tablespoons melted coconut oil or butter
- 1 teaspoon vanilla extract
Optional Add-Ins
- 2 tablespoons dark chocolate chips
- 2 tablespoons chopped pecans or walnuts
- 1 tablespoon chia or flax seeds
Optional Protein Cream Topping
- ½ cup Greek yogurt
- 2 tablespoons cream cheese (softened)
- 1–2 tablespoons powdered sweetener

Equipment Needed
- 8×8-inch baking pan
- Mixing bowls
- Whisk and spatula
- Parchment paper
Step-by-Step Instructions
1. Preheat & Prepare
Preheat oven to 350°F (175°C).
Line your baking pan with parchment paper or lightly grease it. This ensures easy removal and clean slices.
2. Mix Dry Ingredients
In a medium bowl, whisk together:
- Flour
- Almond flour
- Protein powder
- Baking powder
- Baking soda
- Salt
- Pumpkin spice
Whisking evenly distributes the spices and protein.
3. Combine Wet Ingredients
In a large bowl, whisk together:
- Pumpkin purée
- Eggs
- Greek yogurt
- Maple syrup
- Melted coconut oil
- Vanilla extract
Whisk until smooth and creamy.
4. Combine Wet & Dry
Gradually fold dry ingredients into wet mixture.
Mix gently until just combined — do not overmix.
If using chocolate chips or nuts, fold them in now.
The batter should be thick but spreadable.
5. Bake
Spread batter evenly in prepared pan.
Bake for 22–28 minutes, or until:
- Center springs back lightly
- Toothpick comes out clean
Avoid overbaking — pumpkin cakes stay moist but can dry out if baked too long.
6. Cool Completely
Allow cake to cool in pan for 10–15 minutes.
Transfer to wire rack or let cool fully before slicing or frosting.
7. Optional Protein Cream Topping
Mix together:
- Greek yogurt
- Cream cheese
- Sweetener
- Protein powder
Spread over cooled cake for a creamy, tangy topping.
Dust lightly with cinnamon for presentation.
Texture & Flavor Profile
- Moist and tender crumb
- Warm spice aroma
- Subtle sweetness
- Slight tang from Greek yogurt
- Soft but sturdy enough for slicing
The protein blends seamlessly into the batter, enhancing structure without making it dense.
Protein Breakdown (Approximate)
Entire cake: 80–100g protein
Per slice (10 slices): 8–12g protein
A snack cake that actually keeps you full.
Tips for the Perfect Pumpkin Protein Cake
1. Use Real Pumpkin Purée
Not pumpkin pie filling — that includes added sugar and spices.
2. Measure Flour Correctly
Spoon and level — too much flour can dry the cake.
3. Don’t Overmix
Overmixing can toughen protein-based batters.
4. Let It Cool Before Slicing
This helps it firm up and prevents crumbling.
5. Adjust Sweetness
Taste batter before baking (if comfortable doing so) and adjust slightly if needed.
Flavor Variations
Chocolate Pumpkin
Add 2 tablespoons cocoa powder to dry mix.
Maple Pecan
Add chopped pecans and drizzle with maple glaze.
Pumpkin Cheesecake Swirl
Swirl ½ cup sweetened cream cheese mixture into batter before baking.
Pumpkin Cranberry
Fold in dried cranberries for tart contrast.
Espresso Pumpkin
Add ½ teaspoon instant espresso powder for depth.
Storage & Make Ahead
- Store covered at room temperature 1–2 days
- Refrigerate up to 5 days
- Freeze slices individually up to 1 month
If freezing, wrap tightly and thaw overnight in fridge.
Common Mistakes to Avoid
