Ingredients
Equipment
Method
- Preheat your oven to 350°F. Line an 8×8 baking pan with aluminum foil, making sure the edges hang over slightly so you can lift the bars out later.
- In a large bowl, cream together the peanut butter and sugar until smooth. Add the eggs, vanilla, and salt. Mix until everything is fully combined and the batter looks thick and glossy.
- Spread the batter evenly into your prepared pan. Bake for 50 minutes, or until the top looks set and lightly golden. Allow the bar to cool to room temperature.
- While the squares bake, heat the heavy cream in a small saucepan until steaming (not boiling). Remove from heat and stir in the chocolate chips and butter. Keep stirring until the mixture becomes smooth and shiny.
- Once the squares are room temperature, pour the warm chocolate frosting over the top and spread it evenly. Place the pan in the fridge to cool completely before slicing.
- Once chilled for about an hour, you can remove the bars and begin slicing them.
Notes
Tips for Perfect Peanut Butter Squares
- Use creamy peanut butter for the smoothest texture.
- Don’t skip the foil — it makes lifting and slicing so much easier.
- Let them chill fully before cutting; the frosting sets beautifully when cold.
- Warm your knife under hot water for cleaner slices.
- If you prefer a thicker frosting, double the chocolate topping.
Fun Variations to Try
Crunchy peanut butter for extra texture.
Swirl in jam before baking for a PB&J twist.
Add chopped peanuts on top of the frosting.
Use dark chocolate chips for a richer topping.
Try sunflower seed butter for a nut‑free version.
How to Store Them

FAQ
Are these squares gluten‑free? Yes! All the ingredients are naturally gluten‑free. Just double‑check your chocolate chips and peanut butter to be sure.
Can I use natural peanut butter? You can! This is what I use. But stir it very well so the oil is fully incorporated. The texture may be slightly softer in the middle.
Do I have to use heavy cream for the frosting? Heavy cream gives the smoothest, most stable frosting. In a pinch, you can use canned coconut milk but I don’t like the texture as much.
Can I reduce the sugar? A small reduction is fine, but too much will change the texture. These bars rely on sugar for structure.
Can I bake this in a larger pan? Yes, you can bake these in a 9×13 but the bars will be thinner and may bake faster. Start checking around 35 minutes.
Do these freeze well? You can freeze them but sometimes the frosting will get a faded look to it. I would recommend freezing the cookie bottom and then quickly making the frosting on the day you want to use them.
A good recipe always feels a little more special when it becomes part of your family rhythm, and these peanut butter squares fit so easily into that space.
