Preparation Time

Preparation Time: 20 minutes
Chilling Time: 1–2 hours
Total Time: Approximately 1 hour 30 minutes

Ingredients

Chocolate Layers

3 cups milk chocolate chips or semi-sweet chocolate chips
2 tablespoons coconut oil or vegetable shortening

Peanut Butter Filling

1 1/2 cups creamy peanut butter
3/4 cup powdered sugar
4 tablespoons unsalted butter, melted
1 teaspoon vanilla extract
Pinch of salt

How to Prepare a Giant Reese’s Peanut Butter Cup

This dessert is prepared in three main stages: melting the chocolate, creating the peanut butter filling, and assembling the layers.

Step 1: Prepare the Pan

Line a 9-inch round cake pan or springform pan with parchment paper.
Lightly grease the parchment to ensure easy removal.
Set the pan aside.

Using parchment paper ensures the finished dessert releases cleanly and keeps its shape.

Step 2: Melt the Chocolate

Place chocolate chips and coconut oil in a microwave-safe bowl.
Microwave in 30-second intervals, stirring after each, until smooth and fully melted.
Allow the chocolate to cool slightly but remain pourable.

The added fat helps the chocolate stay smooth and glossy.

Step 3: Create the Bottom Chocolate Layer

Pour about half of the melted chocolate into the prepared pan.
Tilt and spread the chocolate evenly across the bottom.
Tap the pan gently on the counter to release air bubbles.
Place the pan in the refrigerator for 10–15 minutes until the chocolate sets.

This forms the sturdy base of your giant peanut butter cup.

Step 4: Make the Peanut Butter Filling

In a medium bowl, combine peanut butter, powdered sugar, melted butter, vanilla extract, and salt.
Stir until smooth, thick, and creamy.
Taste and adjust sweetness if needed.

The filling should be soft but firm enough to hold its shape.

Step 5: Add the Peanut Butter Layer

Remove the pan from the refrigerator once the chocolate base is set.
Spoon the peanut butter mixture over the chocolate layer.
Spread evenly, leaving a small border around the edges so the top chocolate can seal it in.
Gently smooth the surface with a spatula.

This step creates the signature thick peanut butter center.

Step 6: Add the Top Chocolate Layer

Reheat the remaining melted chocolate briefly if needed.
Pour it over the peanut butter layer.
Spread evenly, ensuring the edges are fully covered.
Tap the pan gently to smooth the surface.

The top layer seals the peanut butter filling completely.

Step 7: Chill Until Set

Place the pan in the refrigerator for at least 1 hour, or until fully firm.
For best results, chill for 2 hours.

Proper chilling ensures clean slicing and perfect texture.

Step 8: Remove and Serve

Carefully lift the dessert out of the pan using the parchment paper.
Place on a serving plate.
Slice into wedges using a sharp knife, wiping between cuts.

Serve chilled or slightly softened at room temperature.

Tips for Perfect Results

Use high-quality chocolate

Better chocolate melts smoother and tastes richer.

Do not overheat chocolate

Overheating causes grainy texture. Melt slowly and gently.

Leave space at the edges

This allows the top chocolate layer to seal the filling.

Chill between layers

This prevents layers from mixing and keeps edges clean.

Adjust sweetness

Add more or less powdered sugar to suit your taste.
