Instructions
Make the peanut butter filling:
Place the peanut butter in a heat-safe bowl and microwave for 20 to 30 seconds until it is pourable but not too hot.
Line a No. 8 skillet with parchment paper, allowing some overhang to go up the sides. Pro Tip: crinkle up your parchment paper and then smooth it out in the skillet to help it lay a bit flatter.
Spread the peanut butter into an even layer in the pan. Freeze for an hour or until solid. Remove the parchment paper with the peanut butter from the skillet and return the peanut butter + paper to the freezer. Keep frozen while making the brownie batter.
Make the brownie:
Preheat oven to 350°F. When the skillet has warmed back to room temperature, grease the skillet (including the sides) well with butter.
You don’t want to put a cold skillet in a hot oven as it may damage or even crack your pan!
In a large microwave-safe bowl, combine the butter and chocolate. Microwave in 30-second bursts, stirring between each burst, until the mixture is melted and smooth. Or Mix chocolate and butter in a double boiler and melt. Add the sugar to the hot butter mixture and whisk vigorously until combined. Allow to cool until just barely warm.
Add in eggs and vanilla extract and whisk for about 1 minute, or until very well combined.
Stir in flour, cocoa powder, and salt.
Pour half of the batter into the prepared pan and smooth it out. Peel frozen peanut layer from parchment paper and carefully place the frozen peanut butter over the batter. Pour remaining batter on top, covering completely.
Bake in the preheated oven for 30-40 minutes, or until JUST set to the touch. Pro Tip: Remove the brownies while they're still slightly undercooked, as the hot skillet will keep cooking them after they're out of the oven. This guarantees the perfect level of gooeyness. Gently dust with a layer of powdered sugar and let cool in the skillet for 30 minutes.
These are delightful on their own but for extra deliciousness pair with freshly-whipped cream or vanilla ice-cream!
Brownies can be stored in an airtight container at room temperature for up to 3 days or in the fridge for up to 5 days.
Seasoning Rating: Better
Baking Brownies in a well seasoned cast iron is an excellent way to use your skillet. With that being said, brownies can release moisture as they bake and may interfere with your seasoning if in excess. Generously grease your pan prior to use to protect your seasoning and ensure maximum nonstick capabilities.
Enjoy straight from the pan while they're still nice and warm, but we recommend cleaning things up right after serving and following the Field Method to keep your cast iron in good shape!
Seasoning Ratings:
Best—These dishes are the best options for building resilient seasoning, and surefire choices for getting tricky pans back on track.
Better—The best way to keep your skillet in great shape is to cook frequently, and cast iron-friendly dishes like these are your bread and butter.
Safe—These recipes won't strip seasoning away from your pan, but won't really add any, either.
OK—Be sure to clean up promptly. Recipes with this rating might feature acidic ingredients which can affect seasoning if not washed soon after cooking.
