Keto Crumble Crisp Made in a Cast Iron Skillet

I love a great crumbly crisp crust and still enjoy the original non low-carb version from time to time. However, for this recipe, I use a mixture of almond flour with crushed pecans to create the crunch in this topping. Adding in cinnamon, sweetener and butter, I am able to create the crumbly crisp topping.

Ingredients to Make Blueberry Keto Crisp

The traditional crisp topping recipe uses oats, sugar and butter. Since all of these ingredients are higher in carbs and sugar, I swap them with low-carb, low-sugar options.

For the Blueberry Filling

• Fresh Blueberries
• Lemon Zest
• Xylitol is my preferred low carb sweetener. You could use Swerve, Erythritol, Monk Fruit Sweetener or Stevia

For the Sugar Free Crisp Topping

• Almond Flour
• Pecans, finely chopped
• Butter, cold and sliced into thin chunks
• Sweetener of choice – I use a combination of Xylitol and Stevia
• Cinnamon

Kitchen Essentials you May Need

• Cast Iron Skillet 9″
• Lemon Zester
• Small bowl
• Pastry cutter

How to Make Keto Berry Crisp in a Cast Iron Skillet

Step 1: Prepare the Berries

Regardless of where you purchase the berries, always rinse them well before using.

Step 2: Zest the Lemon

To zest a lemon, you will need a zester, which is a small kitchen tool with a short handle that has a metal head with a row of holes. To zest a lemon, gently scrape the holes of the zester along the surface of the lemon, removing the zest. You are only removing the top layer of skin where the aromatic and tasty oils reside.

Step 3: Prepare Blueberry Filling

In a 9 inch cast iron skillet, add 3 1/2 cups of blueberries. Sprinkle the top of the berries with 3 tablespoons of sweetener, and 1 tablespoon of lemon zest. Gently toss the berries to mix all the ingredients.

Step 4: Prepare the Crisp Topping

In a bowl, add 1 1/2 cups almond flour, 1 cup finely chopped pecans, 2 tablespoons of xylitol sweetener + 1/2 tsp stevia, and 1 teaspoon of ground cinnamon. Mix well. Add 1/2 cup cold butter, cut into small slices, to the mixture. Using the pastry cutter, cut the butter into the mixture until it forms small clumps.

Step 5: Spread Mixture

Spread the crisp mixture evenly over the top of the blueberry mixture.

Step 6: Bake

Bake for 20-25 minutes in a pre-heated oven at 375 degrees. The edges should be bubbling and the crust will be golden brown.

Step 7: Serve

This dessert is delightfully delicious served warm with a scoop of low-carb vanilla ice cream.
