Brownies are my all time favorite dessert. You got lots of chocolate and they are cake-like but gooey. Of course, I like my brownies gooey, not cakey or fudgy. To make it a little more interesting, I decided to make some brownies that are loaded with my favorite additions. White chocolate morsels, peanut butter cups and peanut butter morsels. Full on chocolate heaven!
I’m sure you’ve noticed just how many skillet recipes I’ve been posting lately. I said it many times and I will say it again, I love my cast iron skillet. I’ve made many recipes in it, some I didn’t even have time to post yet, but what I haven’t made yet was dessert. I had to try making a dessert recipe in my cast iron skillet and brownies were my number one choice… always!
I made a little adjustment to my favorite brownie recipe and I had to size it down for the skillet.
*When making this recipe, please NOTE that it is meant for a 12-inch skillet.*
If you only have a 10-inch skillet and really want to make these, which you should, just don’t pour all the batter in it. Pour it in about 2/3 of the way and cook remaining batter in small ramekins or small baking forms. When I have extra batter, I have a couple of small heart baking forms and I use those for leftover batter as special treats for the boys.
Ultimate Peanut Butter Cup Skillet Brownies
Ingredients
- 1/2 cup unsalted butter
- 1/4 cup low fat buttermilk
- 3 cups chocolate chips
- 3 eggs
- 1 cup brown sugar
- 1 tsp vanilla extract
- 1 cup all purpose flour
- 1/2 tsp baking soda
- 1/4 tsp salt
- 1 cup mini Reese's PB cups
- 1/2 cup white chocolate morsels
- 1/2 cup Reese's PB morsels
- 1 cup mini peanut butter cups halved, for topping
Instructions
- Preheat the oven to 350 and make sure that your 12-inch skillet is nicely seasoned. Rub the skillet with little bit of oil, using a piece of per towel, so it's glossy but not wet, on the bottom and up the sides.
- In a small sauce pan, over medium to medium low heat, start melting butter. When butter is almost melted, add 3 cups of chocolate chips. When the chocolate starts to melt as well, add buttermilk. Slowly stir until all melted and smooth.
- Add brown sugar to a large mixing bowl and pour the melted chocolate/butter mixture in it and whisk together.
- Whisk in the eggs, one at a time, mixing after each addition.
- Whisk in vanilla extract.
- Sift in flour, baking soda and salt. Whisk until just combined and smooth.
- Fold in halved mini peanut butter cups, peanut butter morsels and white chocolate morsels.
- Pour the batter into the skillet (if using a 10-inch skillet, make sure to fill in 2/3 of the way and save remaining batter to make in ramekins or muffin pan).
- Bake for 30-35 minutes, do a toothpick test to make sure that the center is not still runny. If needed, bake for another 5-7 minutes.

I just finished making these for my wife’s birthday (they’re still warm). She loves anything chocolate + peanut butter, and this got a huge stamp of approval from both of us. Delicious and really quite easy to make. Thanks for sharing!
That is awesome!! I’m so grad that you both liked it and Happy Birthday to your wife!
Can these be made not in a skillet?
Hi Casey! Yes, try using like a pie dish and that should work.
Cooked brownies exactly as prescribed in recipe. At the end of 30 minutes the mix had risen and poured into the bottom of the oven. Smoke began to fill the kitchen. VERY disappointed in this outcome, wasted all of these ingredients. Brownies, oven, and kitchen are cooling off. After making some google searches, several comments suggest turning down the heat and extending the time. Maybe this will save someone ingredients. Perhaps only filling the pan half way will work better. Again, pretty disappointed.
I’m sorry that you had a disappointing experience! Did you use a 12-inch or a 10-inch skillet (or larger/smaller)? The mix will rise even if you lower the temperature, you’d just have to make sure that you are using a large enough skillet.
Again, I’m sorry it overflowed on you!
Hi! These brownies look so delicious! The pictures are absolutely tempting and I’m looking forward to try them in my own oven 🙂

Brownies are one of my all time favorite desserts. I’m falling more and more in love with my cast iron skillet too. It’s just so darn versatile! Loving the recipe!
Oooo these will be dangerous in my house. I can see myself eating the whole skillet. Can’t wait to try them!
This looks absolutely wonderful! I have made a skillet chocolate chip cookie, but never a brownie skillet. I think I will have to get my skillets out soon! Thanks for sharing this.
Amazing is right Lyuba! I am pretty sure I could eat my weight in these delicious brownies, can’t wait to make them for my hubby 🙂
These look ridiculously gooey and chocolatey and they are pure perfection! My sons would absolutely love them. Thanks!
This looks sooooooooooooooooooo GOOD! Can’t wait to try it!! Saw you on the link up. Great blog, can’t wait to keep coming back to check out new recipes. =D
Oh my gosh Lyuba.. you did it again. *drool*
The brownies look delicious!! I do like chocolate. Have you ever tried making it with a less sweet chocolate. I love the bitter stuff and I wonder if you could do it in a brownie. Your photos are awesome.
