Ingredients
- 2 cups almond flour, superfine
- 1/2 cup creamy peanut butter (unsweetened)
- 1/3 cup sugar-free maple syrup or liquid monk fruit sweetener
- 1/4 cup melted grass-fed butter or coconut oil
- 1 teaspoon vanilla extract
- 1/2 cup keto-friendly dark chocolate chips
- 1 tablespoon coconut oil (for the glaze)
- 1/4 teaspoon sea salt
Directions
Step 1: Preparation
Line an 8×8-inch square baking pan with parchment paper, leaving a slight overhang on the sides for easy removal later. In a large mixing bowl, combine the almond flour, creamy peanut butter, melted butter, sweetener, vanilla extract, and sea salt. Stir the mixture vigorously until a thick, dough-like consistency forms. If the mixture feels too dry, add an extra tablespoon of peanut butter.
Step 2: Creating the Base
Transfer the dough into the prepared baking pan. Use a spatula or the back of a large spoon to press the mixture firmly and evenly into the corners of the pan. Ensure the surface is flat and level, as this creates the foundation for your fat bomb bars. Place the pan in the freezer for about 10 minutes to firm up while you prepare the topping.
Step 3: Melting and Topping
Combine the keto chocolate chips and one tablespoon of coconut oil in a microwave-safe bowl. Microwave in 30-second intervals, stirring between each, until the chocolate is completely smooth and glossy. Remove the pan from the freezer and pour the melted chocolate over the almond flour base. Spread it evenly using a spatula. Sprinkle a little extra sea salt on top if desired.
Step 4: Chilling and Slicing
Place the pan back into the refrigerator for at least 1 hour, or until the chocolate top has completely hardened. Once set, use the parchment paper overhang to lift the entire block out of the pan. Use a sharp knife to slice the block into 12 even bars. Serve immediately or store them for later.
Expert Tips for Perfect Keto Desserts Bars Low Carb Under 20g Easy Delicious Amazing Fat Bombs Meal Prep
To get clean cuts, run your knife under hot water and wipe it dry before slicing through the cold chocolate layer. This prevents the chocolate from cracking. Always use “superfine” almond flour rather than almond meal to ensure a smooth, melt-in-your-mouth texture. If you are sensitive to dairy, you can easily swap the butter for refined coconut oil without losing the structural integrity of the bars. For the best flavor, choose a high-quality sea salt like Maldon to sprinkle on top; the contrast between the salt and the dark chocolate is incredible.
Delicious Variations
You can easily customize these bars to suit your taste preferences. If you have a nut allergy, swap the almond flour for sunflower seed flour and the peanut butter for sunflower seed butter. For a “Crunchy Bar” version, stir in some crushed pecans or walnuts into the base mixture. If you love a mocha flavor, add a teaspoon of instant espresso powder to the melted chocolate topping. You can also swap the dark chocolate for keto white chocolate chips for a creamier, sweeter profile.

Frequently Asked Questions
Can I store these at room temperature?
It is best to keep these bars in the refrigerator or freezer. Because they use natural fats like butter and coconut oil, they will soften significantly if left out on the counter for too long.
How long do these bars last in the freezer?
These bars are excellent for long-term meal prep. When stored in an airtight container or a freezer-safe bag, they will stay fresh and delicious for up to 3 months.
Are these bars suitable for a vegan keto diet?
Yes, they are! Simply ensure you use coconut oil instead of butter and verify that your keto chocolate chips do not contain milk solids.
What if my dough is too crumbly?
Crumbly dough usually means the almond flour was packed too tightly or the peanut butter was a bit dry. Add a teaspoon of water or melted coconut oil at a time until the dough holds together when pressed.
Can I use a different sweetener?
You can use granulated erythritol or xylitol, but a liquid sweetener or a powdered version works best to maintain a smooth texture. If using granulated, pulse it in a blender first to turn it into a powder.
