Add a scoop of sugar-free vanilla ice cream, and this keto dessert is drool-worthy!

So, when I needed to make a quick dessert for my family and realized I had some fresh blueberries to use up, I knew I could make something special!

How To Make Keto Blueberry Crisp

Making this low-carb blueberry crumble really is super simple, and it’s sure to become your new go-to keto dessert! No electric mixer or fancy tools are needed to make this!

You’ll start by making the blueberry filling, this is as easy as mixing together your fresh (or frozen!) blueberries with your sugar substitute, lemon juice, lemon zest, and salt in a medium bowl. That’s it!

Add your blueberry mixture to the prepared baking dish and set it aside while you make the keto crisp topping.

Next, in another medium bowl, combine the almond flour, chopped walnuts, sugar substitute, cinnamon, ginger, nutmeg, and salt. 

Then, you’ll cut the cold butter into smaller pieces and add it to the dry ingredients mixture.

Now it’s time to get a little hands-on, using your fingers you’ll press the butter into the almond flour mixture until it has a crumbly pea-sized texture.

It’s important that your butter be cold, straight from the fridge for this, and not room temperature! Otherwise, you won’t be able to achieve the crumbly texture.

Sprinkle the crumble topping over the blueberry mixture, cover with foil, and bake for about 40 minutes, then remove the foil and bake for another 10 minutes or so until the topping is golden brown.

Serve while still warm with whipped cream or low-carb vanilla ice cream.

You can store any leftovers (if you have any!) in the refrigerator for up to 3 days or freeze it for up to 3 weeks. Winning!

Best Sugar Substitute Options For Keto Blueberry Crisp

When it comes to choosing your sweetener, I have several low-carb options that work well with this sugar-free blueberry crisp recipe.

I really like Lakanto Monk Fruit Sweetener because the texture is spot on and because there is barely any aftertaste.  

This is a great one, especially if you are new to sugar substitutes because it mimics sugar the most in my book.

I’m also partial to Swerve and erythritol blend. However, you should keep in mind that it does have a bit more of a cooling aftertaste that some people dislike. 

Alternatively, you could also use stevia and erythritol-based brand like Pyure.  This is if you prefer to use stevia in your baked goods. If you go this route, you need to reduce the amount by half since it is twice as sweet. 

Lastly, if you can’t easily find a more natural sugar substitute, you can also use Splenda with great success.

I know not everyone would agree with me here, and I respect that, but in my book, it’s still better than regular sugar.
