Equipment Needed
– 10-inch cast iron skillet
– Mixing bowls (large and medium)
– Measuring cups and spoons
– Whisk
– Rubber spatula
– Microwave-safe bowl or small saucepan
– Parchment paper (optional, for easier removal)
– Cooling rack
Step-by-Step Instructions

1. Preheat and Prepare: Set your oven to 350°F (175°C). If your cast iron skillet isn’t well-seasoned, lightly grease it with butter or line with parchment paper for easier removal.
2. Melt Butter: In a microwave-safe bowl or small saucepan, melt the butter completely. Allow it to cool slightly before using.
3. Mix Wet Ingredients: In a large mixing bowl, whisk together the melted butter and sugar until combined. Add eggs one at a time, beating well after each addition. Stir in the vanilla extract.
4. Combine Dry Ingredients: In a separate bowl, whisk together the flour, cocoa powder, and salt.
5. Create Batter: Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix. Fold in half of the chocolate chips and half of the chopped Reese’s cups.
6. Prepare Skillet: Pour the brownie batter into your prepared cast iron skillet, spreading it evenly with a spatula.
7. Add Peanut Butter Swirl: Warm the peanut butter in the microwave for about 20 seconds to make it more pourable. Dollop spoonfuls of peanut butter on top of the batter and use a knife to create swirls throughout.
8. Add Toppings: Sprinkle the remaining chocolate chips and Reese Pieces Cookies over the top of the batter. Press the remaining chopped Reese’s cups slightly into the surface.
9. Bake: Place the skillet in the preheated oven and bake for 30-35 minutes. The edges should be set, but the center should still be slightly gooey. For the perfect Reeses Skillet Brownie Dessert, avoid overbaking – it will continue to set as it cools.
10. Cool: Let the brownie cool in the skillet for at least 15 minutes before serving.
11. Serve: For the ultimate experience, serve warm with a scoop of vanilla ice cream on top.
Troubleshooting & Pro Tips
– Skillet Temperature: Cast iron retains heat, so the brownie will continue cooking slightly after removal from the oven. For a gooier center, remove it a minute or two earlier than you think necessary.
– Peanut Butter Swirls: If your peanut butter is too thick to swirl, mix it with 1-2 teaspoons of neutral oil before warming it.
– Edge Lovers: If you prefer the crispy edges, use a smaller skillet for a thicker brownie with more edge area.
– Cutting Clean Slices: Let the brownie cool completely before cutting if you want clean slices. Use a sharp knife and wipe it clean between cuts.
– Chocolate Choices: For a more complex flavor, use a mix of semi-sweet and dark chocolate chips.
– Check for Doneness: Insert a toothpick about 2 inches from the edge of the skillet – it should come out with a few moist crumbs, not completely wet batter.
Storage & Make-Ahead Tips
– Room Temperature: Store leftover brownie covered with foil or plastic wrap at room temperature for up to 3 days.
– Refrigerator: For longer storage, refrigerate for up to a week. The texture will become more fudgy when chilled.
– Freezer: Cut into individual portions, wrap tightly in plastic wrap and aluminum foil, and freeze for up to 3 months.
– Reheating: To enjoy warm, microwave individual portions for 20-30 seconds, or place the skillet in a 300°F oven for 5-10 minutes.
– Make-Ahead: Prepare the batter up to a day ahead and refrigerate in an airtight container. Let it come to room temperature for about 30 minutes before baking.

FAQ
Can I make this in a regular baking pan instead of a cast iron skillet?
Yes! A 9×9-inch baking pan works well as a substitute. You may need to adjust the baking time slightly, so keep an eye on it.
How do I know when my brownie is done?
The edges should be set and slightly pulled away from the sides of the skillet, while the center should still be slightly soft. A toothpick inserted about 2 inches from the edge should come out with a few moist crumbs.
Can I make this recipe gluten-free?
Absolutely! Simply substitute the all-purpose flour with your favorite 1:1 gluten-free flour blend.
What’s the best way to serve this dessert?
For the ultimate experience, serve warm with a scoop of vanilla ice cream on top. The contrast between the warm, gooey brownie and cold ice cream is divine.
Can I use natural peanut butter in this recipe?
Yes, though the consistency might be different. Natural peanut butter tends to be runnier, which actually makes it easier to swirl into the batter.
Is there a dairy-free version of this recipe?
Yes, substitute the butter with coconut oil and use dairy-free chocolate chips and peanut butter cups (some specialty brands make these).
