- 1 teaspoon coconut oil
- 2 (18 ounce) packages brownie mix with walnuts (such as Ghirardelli®)
- 2/3 cup unrefined coconut oil
- 1/2 cup water
- 2 eggs
- 1 (8 ounce) package cream cheese, softened
- 1/2 (13 ounce) jar chocolate-hazelnut spread (such as Nutella®)
- Preheat oven to 325 degrees F (165 degrees C). Grease a large cast iron skillet with 1 teaspoon coconut oil.
- Mix brownie mixes, 2/3 cup coconut oil, water, and eggs together in a large bowl.
- Combine cream cheese and chocolate-hazelnut spread in another bowl. Fold into the brownie mixture. Spread evenly in the cast iron skillet.
- Bake in the preheated oven until a toothpick inserted into the center comes out with a few moist crumbs attached, about 1 hour. Let cool in the skillet, about 20 minutes.
- Run a knife around the skillet to release edges. Cover skillet with a large platter and flip brownies onto the platter. Let cool completely before cutting into squares, about 40 minutes.
