Ingredients you’ll need

Here’s a list of ingredients you’ll need to make these bars. You can find my recipe card at the bottom of this post for the complete list with their amounts.

Smooth peanut butter: For added crunch, you can use crunchy peanut butter.
Icing/powdered sugar
Unsalted butter: Melted.
Vanilla extract
Salt: Optional, but helps balance out the sweetness.

For the Chocolate Layer:

Milk chocolate
Smooth peanut butter: Again, if you fancy a crunchy chocolate layer, use crunchy peanut butter.

How to make No-Bake Chocolate Peanut Butter Bars

To make these bars, simply grab a large mixing bowl, and add the peanut butter, icing sugar, melted butter, vanilla, and salt.

Mix until completely combined. You should have a very thick dough.

Drop the peanut butter mixture into an 8×8-inch square pan lined with parchment paper, and spread out into an even layer.

You may need to use your hands to get it into the corners.

For the milk chocolate layer, add the chocolate and peanut butter to a microwave-safe bowl and heat in 30 second intervals, stirring after each one, until melted and smooth.

Pour the chocolate mixture over the peanut butter layer, and spread out evenly.

Refrigerate for 2 – 4 hours (or freeze for 1 – 2 hours) until the bars are completely firm and the chocolate topping is set.

Once chilled, slice into squares and enjoy!

NOTE: For best results, I highly recommend using the gram measurements (with a digital scale), rather than the cup measurements. Cup measurements are simply not accurate enough, and I cannot guarantee the best results if you use them.
