Prep Time: 25 minutesChill Time: 3 hoursTotal Time: 3 hours 25 minutesServings: 12 slicesCourse: DessertCuisine: AmericanIngredients3 cups milk chocolate or semi-sweet chocolate chips2 cups creamy peanut butter1½ cups powdered sugar½ cup unsalted butter, softened1 teaspoon vanilla extract¼ teaspoon saltChopped peanut butter cups, optional for toppingFlaky sea salt, optional for toppingInstructionsMelt the chocolate: Place the chocolate chips in a microwave-safe bowl. Microwave in 20–30 second intervals, stirring well after each interval, until completely melted and smooth.Make the chocolate shell: Pour about half of the melted chocolate into a 9-inch fluted tart pan. Spread the chocolate evenly across the bottom and slightly up the sides to create a shell.Chill the base: Place the pan in the refrigerator for about 15–20 minutes, or until the chocolate is firm.Prepare the peanut butter filling: Add the creamy peanut butter and softened butter to a large mixing bowl. Beat until smooth and creamy.Gradually add the powdered sugar, vanilla extract, and salt. Mix until you have a thick, smooth peanut butter filling.Add the filling: Remove the chocolate shell from the refrigerator. Spoon the peanut butter mixture over the chocolate and spread it into an even layer. Leave a little room around the top for the remaining chocolate.Add the chocolate topping: Pour the remaining melted chocolate over the peanut butter filling. Spread it gently until the entire surface is covered.If desired, sprinkle chopped peanut butter cups or a small amount of flaky sea salt over the top before the chocolate sets.Chill: Refrigerate the pie for at least 2–3 hours, or until the chocolate and peanut butter layers are completely firm.Remove the pie from the refrigerator and allow it to sit at room temperature for about 10–15 minutes before slicing.Use a sharp knife warmed under hot water and dried thoroughly to cut clean slices.Helpful TipsUse milk chocolate for a sweeter, classic candy-inspired flavor.Use semi-sweet chocolate if you prefer a richer and less-sweet dessert.Regular creamy peanut butter gives you the smoothest and most consistent filling.Don't overheat the chocolate, or it may become thick and difficult to spread.Let the pie soften slightly before slicing to reduce cracking.Cut smaller wedges because this dessert is wonderfully rich.StorageKeep leftover Decadent Giant Reese’s Peanut Butter Cup Pie covered in the refrigerator. For longer storage, wrap individual slices securely and freeze them, then thaw them in the refrigerator before serving.Optional ToppingsChopped peanut butter cupsChocolate drizzlePeanut butter drizzleChopped roasted peanutsWhipped creamFlaky sea saltChocolate curlsEnjoy every rich, creamy, chocolatey bite!
