How To Make Keto Blueberry Bars

Making these keto blueberry bars is pretty straightforward. You’ll start by preheating the oven to 350 degrees.

Prepare your baking dish or baking pan by greasing well with butter or parchment paper. I prefer using butter to grease my pan because the butter gives the bars extra flavor.

Then in a large mixing bowl, using an electric mixer, you’ll beat together softened cream cheese, vanilla extract, lemon extract, sugar substitute, plus the eggs one at a time making sure they are well incorporated into the batter.

To the wet ingredients add the almond and coconut flours, baking powder, salt, and xanthan gum and combine well until fully incorporated.

Then you’ll spread half of the batter on the bottom of the prepared pan. This will be the bottom layer.

Once that’s done, you’ll add the blueberries evenly over top. Note if you are using frozen blueberries there is no need to defrost.

Next, you’ll cover the blueberries with the remaining cookie bar dough before baking them for about 30 minutes or until golden brown in the preheated oven.

To make the keto vanilla icing simply mix all the ingredients in a separate bowl.

Once the bars have been allowed to cool, you can drizzle the top with the vanilla icing. 

Store any leftovers in an airtight container in the refrigerator for five days or in the freezer for up to three weeks.

Best Sugar-Substitutes For Sugar-Free Blueberry Bars

You can use your sweetener of choice but it needs to be sugar-free and keto-friendly, my top choice is a monk fruit erythritol blend for best results. My personal favorite is Lakanto’s brand. 

I also use Swerve an erythritol sugar substitute with great success.

You could also use a stevia and erythritol-based brand like Pyure for most of my baked goods. However, if using Pyure, you will want to use half the amount called for in this recipe since it’s a much sweeter choice. 

Lastly, if you can’t easily find a more natural sugar substitute you can also use Splenda or a generic brand of the same. I know not everyone would agree with me here and I respect that but in my book, it’s still better than regular sugar.

However, when it comes to the keto vanilla glaze you will have to use a confectioner’s sugar substitute. Both Lakanto and Swerve have great ones.
