How to make Keto Peanut Butter Bars

This recipe has several steps, but it’s still very easy to make! This recipe is perfect for beginner cooks or a family meal prep day! The majority of the work takes place in a food processor or a very strong blender.

First, you’ll start by grinding your peanuts in a food processor until it crumbles to the consistency of graham cracker crumbs. Then you’ll incorporate your creamy ingredients (like butter, sweetener, and peanut butter), followed by coconut flour and vanilla extract. This multi-step process will require you to scrape the sides of the processor down with a spatula several times, but the stop-and-go is worth it for these delicious bars!

Finally, scrape the thick batter onto a pan (8×8 lined with parchment paper). Spread it to a nice even layer and allow it to chill for 30 minutes. While this is chilling, heat the heavy cream and add chocolate and peanut butter. Remove from heat and stir until super smooth. Pour this over the chilled peanut butter layer and chill for another hour before cutting and serving.

How to store No Bake Peanut Butter Bars

These peanut butter bars are best kept chilled in an airtight container in the fridge for up to 5 days. To keep fresh for longer, freeze and eat within 3 months for the best taste and texture. These will get softer as they get closer to room temperature, so keep that in mind if serving for a party or gifting to others.

When storing these, make sure to place a layer of parchment or wax paper between the bars if storing on top of one another. This will help prevent them from sticking or getting misshapen.

Tips for the BEST Peanut Butter Chocolate Bars

Use a high-quality food processor or blender. This mixture is very thick, and weaker appliances may not be able to handle this.
Make sure to line the pan with parchment paper, aluminum foil, or wax paper before spreading the mixture. The peanut butter layer is quite sticky, and it would be very difficult to remove pieces if you put this directly into an unlined pan.
Use roasted peanuts or roast raw peanuts for this. Roasted peanuts are able to achieve a creamier texture and provide a greater depth of flavor. You can use salted or unsalted (if using salted, make sure to use unsalted butter).
Don’t skimp on the chilling time. You want the peanut butter layer to be cold and well-set so that the warm chocolate layer doesn’t melt and seep into the peanut butter layer. If you don’t allow it to chill long enough before cutting, you’ll have a gooey mess.

What to serve with No Bake Peanut Butter Bars

This is the perfect afternoon treat to power you through the rest of a long day, especially when served with a Keto Frappuccino (maybe try this Salted Caramel version, or this Mocha one?)! This Vanilla Bean Frappuccino is low carb and a great option if you don’t love coffee or if you’ve got a little one wanting some homemade Starbucks, too!

For a nighttime treat, serve these No Bake Peanut Butter Bars with a Keto Hot Cocoa with Espresso Whipped Cream!
