It has all the iconic flavor and texture of the original candy, scaled up into an impressive, sharable dessert that’s surprisingly easy to make at home.

The combination of rich milk chocolate and sweet, creamy peanut butter filling is simple, but magical. Whether you’re making this for a party, a birthday surprise, or just because your sweet tooth demanded it, this oversized treat will turn heads and win hearts.

What Kind of Chocolate Should I Use?

Stick to good-quality milk chocolate for the most authentic Reese’s-style experience. You can use baking bars or chocolate chips—just make sure they melt smoothly. If you love darker chocolate or want to cut the sweetness a bit, semisweet or bittersweet chocolate works too.

Ingredients for the Giant Reese’s Peanut Butter Cup

3 cups milk chocolate chips (or chopped milk chocolate)
1 1/2 cups creamy peanut butter
1/2 cup powdered sugar
1/4 teaspoon salt
1 tablespoon unsalted butter
1 teaspoon vanilla extract

How To Make the Giant Reese’s Peanut Butter Cup

Step 1: Melt and Spread the Base Chocolate

Melt 1 1/2 cups of the chocolate chips in a microwave-safe bowl in 30-second intervals, stirring between each until smooth. Pour into a 9-inch tart pan with a removable bottom and use a spoon or spatula to evenly spread the chocolate across the base and up the sides. Chill for 10 minutes to firm up.

Step 2: Make the Peanut Butter Filling

In another bowl, combine peanut butter, powdered sugar, salt, butter, and vanilla. Stir until the mixture becomes thick and smooth. It should resemble a soft dough.

Step 3: Add the Filling

Once the chocolate shell has firmed up, gently press the peanut butter filling into the shell, smoothing it into an even layer without breaking the chocolate.

Step 4: Top with More Chocolate

Melt the remaining 1 1/2 cups of chocolate and pour it over the peanut butter layer. Use a spatula to smooth the surface and gently tap the pan to remove air bubbles.

Step 5: Chill and Serve

Refrigerate the entire peanut butter cup for 1 to 2 hours, or until completely set. Once chilled, remove from the tart pan, slice like a pie, and serve!

How to Serve and Store the Giant Reese’s Peanut Butter Cup

This dessert is best served chilled or at room temperature, sliced into thin wedges—it’s rich, so a little goes a long way! Store leftovers in an airtight container in the fridge for up to 5 days. For longer storage, freeze individual slices wrapped tightly in plastic and foil.
