Yummy brownies made with lots of mini peanut butter cups, peanut butter morsels and white chocolate morsels! Super chocolaty and loaded with peanut butter flavors!
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.
