Ingredients

For the Blueberry Filling:

1 cup (148 g) blueberries
2 tbsp water
¼ cup (50 g) allulose sweetener
¼ tsp glucomannan (or xanthan gum)

For the Crust:

1 ¾ cups (196 g) almond flour
¾ cup (60 g) shredded coconut
½ cup (100 g) erythritol sweetener
2 tbsp (14.2 g) coconut flour
½ tsp salt
6 tbsp (85.21 g) butter (melted)
½ tsp vanilla extract

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

1. Make the filling:

In a medium saucepan over medium heat, combine the blueberries, allulose sweetener, and water. Bring to a boil, then reduce the heat and simmer for 10 minutes, until the berries are softened and easy to mash. Mash the blueberries slightly, then sprinkle with glucomannan and whisk vigorously to combine. Let the filling cool.

2. Prepare the crust:

Preheat your oven to 350°F (175°C) and lightly grease an 8×8-inch metal baking pan. In a large bowl, whisk together the almond flour, shredded coconut, erythritol sweetener, coconut flour, and salt. Stir in the melted butter and vanilla extract until the dough begins to clump together.

3. Form the base crust:

Press half of the crust mixture firmly into the bottom of the prepared pan. Bake for 10 minutes, then remove from the oven and let cool for 10 minutes.

4. Assemble the bars:

Spread the cooled blueberry filling evenly over the partially baked crust. Sprinkle the remaining crust mixture over the top of the blueberries. Lightly press the top crust into the filling to help it adhere.

5. Bake the bars:

Bake for an additional 20-25 minutes, or until golden and bubbly. Remove from the oven and let cool completely before cutting into bars.

Storage/Reheating

FAQs

Can I use frozen blueberries instead of fresh?

Yes, frozen blueberries work great in this recipe. Just make sure to thaw them before using to avoid excess moisture in the filling.

What is glucomannan, and can I use something else?

Glucomannan is a keto-friendly thickening agent made from the root of the konjac plant. If you don’t have it, xanthan gum is a suitable substitute.

Can I make these bars dairy-free?

Yes, use dairy-free butter (such as coconut oil) to make these bars dairy-free.

Can I make this recipe without the coconut flour?

Coconut flour helps to bind the crust and adds a slight coconut flavor. You can try replacing it with more almond flour, but the texture may change slightly.

How do I know when the bars are done?

The bars are done when the edges are golden brown, and the top is slightly firm to the touch. You can also insert a toothpick into the center to check for doneness—if it comes out clean, the bars are ready!
