Ingredients You’ll Need
For the Almond Flour Crust:
- 2 cups almond flour
- 1/4 cup coconut flour
- 1/3 cup coconut oil or grass-fed butter, melted
- 1/4 cup maple syrup (for paleo) or keto-friendly sweetener (like monk fruit or erythritol)
- 1 egg
- 1 tsp vanilla extract
- 1/4 tsp sea salt
For the Blackberry Filling:
- 1 1/2 cups fresh or frozen blackberries
- 2–3 tbsp lemon juice
- 2–3 tbsp sweetener of choice
- 1 tbsp chia seeds (helps thicken the filling naturally)

How to Make Keto Paleo Blackberry Pop Tart Bars
Step 1: Prepare the Blackberry Filling
In a saucepan over medium heat, combine blackberries, lemon juice, and sweetener. Stir frequently, and mash the berries slightly to release their juices. Simmer for 5–7 minutes, then add chia seeds. Stir and cook for 2–3 more minutes until thickened. Remove from heat and cool completely.
Step 2: Make the Dough
In a large bowl, mix almond flour, coconut flour, and salt. Add melted coconut oil or butter, sweetener, vanilla, and the egg. Stir until a soft dough forms. If the dough feels too dry, add a tiny splash of almond milk.
Step 3: Assemble the Bars
Line a square 8×8″ baking pan with parchment paper. Press half of the dough evenly into the bottom of the pan to form the crust. Spread the cooled blackberry filling over the crust. Carefully press or spread the remaining dough over the top — it’s okay if some filling peeks through.
Step 4: Bake
Bake at 350°F (175°C) for 22–28 minutes, or until the top is lightly golden and firm to the touch. Let the bars cool in the pan before slicing. Cooling is essential for the bars to set and hold their shape.
Step 5: Add Glaze (Optional)
Once cooled, drizzle the bars with a glaze made from powdered sweetener and non-dairy milk or lemon juice. Let the glaze harden slightly before serving.

Recipe Variations
- Berry Swap: Use raspberries, blueberries, or a mixed berry blend for the filling.
