FAQs

Can I use natural peanut butter?

Yes, but make sure it’s well-stirred and not too oily or runny, as that can affect texture.

Some versions call for a quick stovetop mixture, while others are completely no-bake. Both work well.

Can I use milk chocolate instead of dark?

Absolutely—choose whichever chocolate you prefer for the topping.

How do I make clean cuts?

Chill the bars fully, then use a sharp knife warmed under hot water and wiped dry before each cut.

Can I double the recipe?

What’s the best way to melt chocolate?

Use a microwave in 20-second intervals or a double boiler for smooth results.

Can I add layers or toppings?

Yes! Try adding crushed pretzels, peanuts, or even mini marshmallows between the peanut butter and chocolate layers.

Is there a gluten-free version?
