Ingredients
Method
- Preheat and prep: Heat oven to 350°F (175°C). Grease a 9x9-inch baking dish or a deep 8x8-inch dish.
- Make the pumpkin base: In a large bowl, whisk together pumpkin puree, eggs, heavy cream, 1/2 cup granulated keto sweetener, 2 teaspoons vanilla, 2 teaspoons pumpkin pie spice, and 1/4 teaspoon salt until smooth.
- Pour into the dish: Spread the pumpkin mixture evenly in the prepared baking dish.
- Mix the topping: In a separate bowl, combine almond flour, remaining 1/6 cup granulated sweetener (about 2 tablespoons), baking powder, remaining 1/4 teaspoon salt, and chopped nuts if using. Stir in melted butter until the mixture looks like moist crumbles.
- “Dump” and spread: Sprinkle the almond flour mixture evenly over the pumpkin base. Don’t press it down too hard—lightly level it with your fingers or a spoon.
- Bake: Place on the center rack and bake 40–50 minutes, until the topping is golden and the pumpkin layer is set at the edges but slightly jiggly in the center.
- Cool properly: Let it cool at room temperature for at least 30–45 minutes. The filling will continue to set as it cools.
- Chill for clean slices: For the neatest cuts, refrigerate at least 2–3 hours or overnight. Serve chilled or gently warmed.
- Finish and serve: Dust with powdered keto sweetener if you like, and add a dollop of whipped cream. Slice and enjoy.

How to Store
- Refrigerator: Cover the pan or transfer slices to an airtight container. Store up to 5 days.
- Freezer: Wrap individual slices tightly and freeze up to 2 months. Thaw overnight in the fridge before serving.
- Reheat: Warm in a 300°F (150°C) oven for 10–12 minutes, or microwave gently in 15–20 second bursts to avoid melting the topping.
Why This is Good for You
- Low in carbs: Uses almond flour and keto sweetener to keep net carbs low while still tasting like a classic fall dessert.
- High in fiber: Pumpkin brings natural fiber, which supports digestion and helps keep you satisfied.
- Healthy fats: Butter, cream, and nuts deliver satiating fats that fit a ketogenic lifestyle.
- No refined sugar: Sweetness comes from erythritol or allulose, which won’t spike blood sugar the way regular sugar does.
What Not to Do
- Don’t use pumpkin pie filling: It’s pre-sweetened and will add unwanted sugar and carbs.
- Don’t skip the cooling step: Cutting too soon can make the center look runny.
Let it set for the best texture.
- Don’t overbake: If the top is browning too fast, tent with foil. The center should have a slight wobble when you pull it out.
- Don’t pack the topping down: You want a crumbly, tender layer, not a dense crust.
- Don’t guess your sweetener: Different sweeteners taste and bake differently. Adjust to taste, especially if using allulose, which is less sweet than erythritol.
Variations You Can Try
- Dairy-free: Swap heavy cream for full-fat coconut milk and butter for coconut oil or vegan butter.
- Extra spice: Add more cinnamon or a pinch of cardamom for a deeper aroma.
- Pecan streusel: Increase nuts to 3/4 cup and add 1/2 teaspoon cinnamon to the topping for a bakery-style crunch.
- Maple vibe: Use a keto-friendly maple syrup or maple extract (1/2 teaspoon) in the pumpkin layer.
- Mini bakes: Divide the batter into ramekins and reduce baking time to 25–30 minutes for individual servings.
- Chocolate swirl: Drizzle a few tablespoons of melted sugar-free chocolate over the topping right after baking.
FAQ
Can I use coconut flour instead of almond flour?
Coconut flour behaves very differently and is much more absorbent.
If you must use it, reduce the flour amount significantly and increase the fat and liquid, but the texture won’t match the original. Almond flour is strongly recommended here.
What sweetener works best?
Allulose gives the softest texture and no cooling aftertaste, but it’s less sweet, so you may want a bit more. Erythritol or a blend like monk fruit with erythritol works well too.
Taste your mixture before baking and adjust slightly if needed.
Can I make this ahead for the holidays?
Yes, it’s perfect for making a day in advance. Bake, cool, and refrigerate. The flavors meld beautifully overnight, and slices cut cleanly when chilled.
How do I know it’s done?
The edges should look set and the center should jiggle slightly when you nudge the pan.
If the top is browning too quickly before the center sets, tent loosely with foil and continue baking.
Is canned pumpkin the same as pumpkin pie filling?
No. Canned pumpkin is pure pumpkin with no sugar or spices added. Pumpkin pie filling is pre-sweetened and spiced, which isn’t keto-friendly for this recipe.
Can I serve it warm?
Yes, but let it cool at least 30 minutes first.
If you want it warm later, chill it to set, slice, and then reheat gently so the pieces stay neat.
What size pan is best?
A 9×9-inch pan gives a nice balance of thick filling and crisp topping. An 8×8-inch pan works too but may need a few extra minutes in the oven due to the thicker center.
Final Thoughts
This Keto Pumpkin Pie Dump Cake brings all the cozy fall flavors with none of the sugar crash. It’s simple to make, easy to customize, and tastes even better the next day.
