Cosmic Skillet Brownie

A take on the classic Cosmic Brownies, but this time made in a large skillet! A chewy, fudgy brownie covered in a shiny chocolate ganache, and topped with rainbow covered chocolate chips. This skillet brownie is out of this world!
Ready for some nostalgia? I remember getting so excited when my mom would get me Little Debbie’s cosmic brownies. Having one as a dessert after dinner, or even better, bringing one to school? That was a treat! But guess what? Now that we’re adults, we can have these brownies whenever we want! So I got to work playing with my brownie recipe to make a chewier version that is perfect to just dig into and get that awesome bite of nostalgia!
What You’ll Need. . .
- unsalted butter
- canola oil
- brown sugar
- granulated sugar
- eggs
- vanilla extract
- semi-sweet chocolate chips
- flour
- cocoa powder
- baking soda
- salt
- heavy cream
- cosmic sprinkles (I use similar to these)
Making the Brownie
- Melt the butter and mix it with oil in a large bowl. Add in sugar and whisk. Next add in the vanilla and eggs and whisk thoroughly for 3-4 minutes. (By the way – this step – the whisking of the eggs – is super important for brownies you’re not topping with a ganache or frosting, because it get’s you that crinkly top! )
- Melt 1/2 cup of chocolate chips in the microwave in 30 second intervals, mixing in between. Let cool 2-4 minutes. Whisk into the batter.
- Toss in the flour, cocoa powder, baking soda, and salt and fold until just mixed in. Don’t overmix it. Next fold in the other 1/2 cup of chocolate chips.
- Butter your cast iron skillet. Preheat oven to 350F. Smooth the batter into the skillet. Bake about 32 minutes. It’s done when a toothpick comes out almost clean – not completely clean. It also shouldn’t be too jiggly, but you don’t want to overbake the brownie. Remove and let come to room temperature.
Making the Ganache Topping
- Place the heavy cream in the microwave for about 30-40 seconds until it is a little bubbly. Then toss in your chocolate chips and mix until melted and smooth.
- Pour the ganache over your brownie. Sprinkle with the cosmic sprinkles. Let this cool completely for 2-4 hours to get a fudgy texture, and let the brownie get that cosmic brownie chewy texture – or eat right away if you want it meltier and can’t wait!
Some notes. . .
- Brownie can be covered with plastic wrap in the pan, or cut and removed into an airtight container, and stored in the refrigerator for up to 5 days – although I doubt you’ll have any left after the first day!
