About the Ingredients

Pumpkin Puree

This creamy base is packed with flavor and nutrients, making it the star of our cake.

Large Eggs

They add structure and richness, helping to bind the cake together beautifully.

Swerve Granular

A fantastic sugar substitute that sweetens without the carbs, keeping this dessert keto-friendly.

Heavy Whipping Cream

It provides a luscious creaminess that elevates the pumpkin filling to new heights.

Pumpkin Pie Spice

This warm blend of spices brings the essence of fall into every bite, enveloping you in cozy flavors.

Almond Flour

A low-carb alternative to regular flour, it gives the cake a delightful texture and nutty flavor.

Tips & Tricks

Use Fresh Pumpkin Puree

If possible, opt for homemade pumpkin puree for an even richer flavor and texture.

Let It Rest

Allow the cake to cool for at least 20 minutes before slicing to achieve the best consistency.

Experiment with Spices

Add a pinch of cinnamon or nutmeg for an extra layer of warmth and flavor.

Keep an Eye on Baking Time

Every oven is different; check for doneness around the 45-minute mark to avoid overbaking.

Pro Tips

  • Ensure Ingredients are Room Temperature: This helps in achieving a smooth and even batter.
  • Don’t Skip the Butter Drizzle: This crucial step adds a lovely richness and helps the topping crisp up beautifully.
  • Use a Glass Dish: A glass baking dish helps you monitor the browning of the top layer effectively.
  • Serve with Whipped Cream: A dollop of sugar-free whipped cream on top transforms this dessert into a showstopper.

Step-by-Step Instructions

Preheat and Prepare

Begin by preheating your oven to 350°F (175°C) and lightly greasing a 9x13-inch baking dish to ensure easy removal.

Mix the Pumpkin Filling

In a large bowl, whisk together the pumpkin puree, eggs, Swerve Granular, heavy whipping cream, pumpkin pie spice, and salt until well combined. Stir in 1/2 cup of the cake mix until the mixture is smooth.

Spread the Base

Pour the pumpkin mixture into your prepared baking dish, spreading it evenly with a spatula for a uniform layer.

Add the Crunch Topping

In a small bowl, combine the chopped pecans and Swerve Brown. Sprinkle the remaining cake mix over the pumpkin layer, then evenly distribute the pecan mixture on top.

Drizzle and Bake

Slowly drizzle the melted butter across the surface, ensuring it seeps into the dry spots. Bake for 45-55 minutes or until the top is golden brown.

Delicious Variations

Chocolate Chip Pumpkin Crunch Cake

Add sugar-free chocolate chips to the pumpkin filling for a delightful twist.

Spiced Apple Variation

Incorporate diced apples and a sprinkle of cinnamon into the pumpkin mixture for a fruity flair.

Coconut Flour Substitute

Swap out almond flour for coconut flour for a different nut-free alternative, adjusting the liquid as needed.

How to Store Keto Pumpkin Crunch Cake

Refrigerator

Store leftovers in an airtight container in the fridge for up to 5 days.

Freezer

Wrap tightly in plastic wrap and foil, and freeze for up to 3 months for long-term storage.

Reheating

Reheat slices in the microwave for 20-30 seconds, or enjoy it chilled straight from the fridge.

Frequently Asked Questions

Can I use regular flour instead of almond flour?

How can I make it sweeter?

Feel free to increase the amount of Swerve Granular or add a bit of sugar-free syrup to taste.

Ingredients

Instructions

  1. 1 Preheat your oven to 350°F (175°C). Lightly grease a 9x13-inch glass or ceramic baking dish.
  2. 2 Mix the filling: In a large bowl, whisk together pumpkin puree, eggs, granular sweetener, whipping cream, pumpkin pie spice, and salt. Then whisk in 1/2 cup of cake mix until smooth and slightly thickened.
  3. 3 Pour the base: Spread the pumpkin mixture evenly into your prepared dish.
  4. 4 Add the crunch: Combine chopped pecans and Swerve Brown in a small bowl. Sprinkle the remaining cake mix over the pumpkin layer, then scatter the pecan mixture evenly on top.
  5. 5 Finish with butter: Slowly drizzle the melted butter across the surface, making sure most of it soaks through the dry spots.
  6. 6 Bake: 45-55 minutes, or until the top is golden brown and slightly firm to the touch. The base will stay soft — that’s what gives it its custardy texture.
  7. 7 Cool or serve warm: Let it rest at least 20 minutes. Serve warm (for a pudding-style dessert) or chilled (for neat, sliceable squares).

Chef's Note

For best results, chill overnight and reheat before serving. Top with keto whipped cream and a sprinkle of cinnamon for an extra festive touch. Store leftovers in the fridge for up to 5 days.
