Keto Peanut Butter Bars (Easy Homemade Keto Bars) ⎮

Peanut Butter Filling:
 ½ cup (120g) smooth all natural peanut butter (no sugar added)
 4 tbsp (54g) butter, melted
 4 tbsp (48g) granulated erythritol
 5 tbsp (38g) finely ground almond flour
 1 tsp sugar-free vanilla extract
 2.50 oz (70g) (approx.) sugar-free chocolate or chocolate with at least 85% cacoa content
 chopped peanuts for decoration (optional)

Mix all of the ingredients for the peanut butter filling in a bowl until you get a smooth and chunk-free mass.


Transfer the mass into a silicone mold for candy making, such as this one.
Leave a bit of space on top of the peanut butter filling for the chocolate bottom.
Place the mold into your freezer and chill for at least 20-30 minutes before proceeding to the next step.


Melt the chocolate using a double boiler and pour part of the chocolate over the partly frozen peanut butter filling (the chocolate shouldn't be too thick nor to thin, aim for approx. 5mm or 0.2").
Place the silicone mold back in the freezer and freeze until solid.
Depending on what silicone mold you're using, this might take a few hours.

Don't discard the chocolate you heated up, just store it somewhere until the bars are solid and will be covered with more chocolate.


Reheat the chocolate you melted before.

Once the naked peanut butter bars are solid enough to be pressed out of the silicone mold without breaking, pop them out and place them on a baking rack with parchment paper placed beneath it.
Pour the chocolate over the peanut butter bars.
Make sure to cover them completely, you can use a spoon to distribute the chocolate evenly.


Optional: Add chopped peanuts onto the top of the peanut butter bars while the chocolate is still liquid for decoration.


Chill the chocolate covered peanut butter bars in your fridge until the chocolate hardened up.

Once the chocolate is hard, you can enjoy them but I'd wait a bit more until the peanut butter filling isn't frozen anymore.
That way you can enjoy a creamy peanut butter bar with crunchy chocolate around it.


Store covered with plastic wrap or in an air-tight container and enjoy for up to a week.
