Keto Peanut Butter Bars (3 Ingredients!)

These keto peanut butter bars are an easy low carb dessert made with just 3 ingredients- No baking required! Soft, chewy, and ready in 5 minutes!

When it comes to keto desserts, those made with peanut butter are my favorite.

Growing up, peanut butter was a staple in my diet. I’d have it with my breakfast, in my sandwich at lunch (obviously with homemade jam!) and in tons of my snacks.

Since starting a keto diet, I’ve still enjoyed peanut butter regularly. However, as my palate changes, I prefer it in my sweets over my other meals.

How to make keto peanut butter bars

The Ingredients.

• Peanut butter– smooth and sugar free peanut butter. If your peanut butter is a little stiff/firm, microwave it for 20-30 seconds to soften.
• Keto maple syrup– Skip the expensive store-bought kind and make your own sugar free maple syrup. It’s easy, delicious, and makes tons!
• Coconut flour– Thickens the mixture and to make the bars soft, firm, and fudgy. 
• Keto chocolate chips– Optional, but drizzle some over the bars. Like the syrup, you can easily make your own.

The Instructions. 

Make the mixture: In a mixing bowl, add the peanut butter, syrup, and coconut flour and mix until a smooth dough remains. 

Transfer it to a pan and refrigerate it: Transfer the mixture into a pan and press it firmly into place, then refrigerate it. If desired, add some melted chocolate on top. 

Slice and serve: After 30 minutes, remove it from the fridge, slice it up and serve. 

Tips for success

• If you find your dough is a little too thin/watery, add more coconut flour. If the dough is too thick/crumbly, add a dash more syrup.
• Allow at least 30 minutes refrigeration time so the bars can firm up. If you are impatient, you can place it in the freezer for 15 minutes.
• Fold through some mix-ins into the mixture, like chopped nuts, seeds, or keto chocolate.
