Step-by-Step Instructions

1. Prepare the Pan

Line your baking dish with parchment paper, letting some hang over the edges. This makes removing the bars a breeze and keeps cleanup simple.

2. Make the Peanut Butter Layer

In a mixing bowl, combine peanut butter, melted butter, and powdered sugar. Stir until smooth and thick. If it feels too dry, add a splash more melted butter; if too wet, add a bit more powdered sugar. Spread the mixture evenly in your prepared pan, pressing gently so it’s packed down.

3. Melt the Chocolate

In a heatproof bowl, combine chocolate chips and a little peanut butter. Melt in 20-second bursts in the microwave, stirring each time until silky smooth. You can also melt it over a double boiler if you prefer.

4. Layer and Chill

Pour the chocolate mixture over the peanut butter base and spread evenly with a spatula. Tap the pan lightly on the counter to smooth out air bubbles. Place in the fridge for at least 2 hours, or until fully set.

5. Slice and Serve

Once the chocolate is firm, lift the bars out using the parchment overhang. Slice into squares or rectangles with a sharp knife. For cleaner cuts, warm the knife under hot water, wipe dry, and slice.

Storage and Serving Tips

Fridge: Store in an airtight container for up to 5 days.
Freezer: Wrap bars individually and store for up to 2 months. Thaw in the fridge before serving.
Serving idea: Sprinkle flaky sea salt on top before chilling for a sweet-salty finish.

FAQs

Can I use natural peanut butter?
Yes, but make sure to stir it well so the oil is fully incorporated.

Can I swap the chocolate chips?
Absolutely — dark, milk, or even white chocolate works.

How do I make them less sweet?
Reduce powdered sugar slightly or use bittersweet chocolate.

Can I make them dairy-free?
Yes — use dairy-free chocolate chips and vegan butter.

Why is my chocolate layer cracking?
It may be too cold when slicing; let it sit at room temp for a few minutes before cutting.
