Equipment Needed
– 10-12 inch cast iron skillet
– Mixing bowls (large and medium)
– Whisk
– Rubber spatula
– Measuring cups and spoons
– Microwave-safe bowl (for melting butter)
– Parchment paper (optional, for easier cleanup)
– Cutting board and knife (for chopping peanut butter cups)
– Oven mitts
Step-by-Step Instructions

1. Preheat and Prepare: Set your oven to 350°F (175°C). Lightly grease your cast iron skillet with butter or cooking spray.
2. Melt Butter: In a microwave-safe bowl, melt the butter in 30-second intervals until completely liquid.
3. Mix Wet Ingredients: In a large bowl, whisk together the melted butter and sugar until well combined. Add eggs one at a time, whisking well after each addition. Stir in the vanilla extract.
4. Combine Dry Ingredients: In a separate bowl, whisk together flour, cocoa powder, and salt.
5. Create Batter: Gradually fold the dry ingredients into the wet ingredients until just combined. Be careful not to overmix.
6. Add Peanut Butter Elements: Gently fold in half of the chopped Reese’s cups and peanut butter chips, saving the rest for topping.
7. Transfer to Skillet: Pour the batter into your prepared skillet, spreading it evenly with a spatula.
8. Add Toppings: Sprinkle the remaining Reese’s cup pieces, Reese’s Pieces, and peanut butter chips on top of the batter.
9. Bake: Place the Reeses Skillet Brownie Dessert in the preheated oven and bake for 30-35 minutes, or until the edges are set but the center is still slightly gooey. A toothpick inserted into the center should come out with a few moist crumbs.
10. Cool Slightly: Allow the brownie to cool in the skillet for 15-20 minutes before serving. This creates the perfect balance between warm gooiness and sliceable texture.
11. Serve: For the ultimate experience, top with vanilla ice cream and a drizzle of warm peanut butter or chocolate sauce just before serving.
Troubleshooting & Pro Tips
– Brownie Too Dry? Reduce baking time by 5 minutes next time. Every oven is different!
– Peanut Butter Cups Sinking? Freeze them for 15 minutes before adding to the batter.
– Perfect Texture: For fudgier brownies, remove from the oven when the center is still slightly jiggly.
– Extra Indulgence: For an even more decadent experience, warm 1/4 cup of peanut butter and drizzle it over the top before serving.
– Even Baking: If your skillet tends to heat unevenly, rotate it halfway through baking.
– Enhanced Flavor: Sprinkle a small amount of flaky sea salt on top just before serving to elevate all the flavors.
Storage & Make-Ahead Tips
– Room Temperature: Cover the skillet with foil and store at room temperature for up to 2 days.
– Refrigerator: For longer storage, cover tightly and refrigerate for up to 5 days. The texture will become more fudge-like when cold.
– Freezer: Cut into portions and freeze individually wrapped pieces for up to 3 months. Thaw at room temperature for 1-2 hours before serving.
– Reheating: To recapture that fresh-baked experience, microwave individual portions for 20-30 seconds or warm the entire skillet (if oven-safe) in a 300°F oven for 10 minutes.
– Make-Ahead: Prepare the batter up to 24 hours in advance, keep refrigerated, and bring to room temperature for 30 minutes before baking.
