Fudge Brownie Muffins

I've already posted the cheesecake version of these muffins here, but they deserve their own post! These are basically a brownie in a cupcake paper, but not as fudgy as my regular brownie recipe. The addition of cinnamon makes them extra special.

Fudge Brownie Muffins
1 cup butter
1/2 cup cocoa
4 eggs
2 cups sugar
2 tsp vanilla
1 1/2 cups flour
1 tsp cinnamon
1/4 tsp salt
1/2 cup mini chocolate chips

1. Preheat oven to 325 degrees. Line 24 muffin cups with liners and lightly spray them with non stick cooking spray.
2. Place butter and cocoa in a microwave safe bowl and microwave on high 1 minute for until butter melts; set aside.
3. Combine 4 eggs, 2 cups sugar, and vanilla in a large bowl. Add the butter and chocolate mixture, flour, cinnamon, salt, and mini chocolate chips. Stir until blended.
4. Using a large scoop, fill muffin cups with brownie batter. Bake for 25 minutes. Cool in pans for 10 minutes, then remove to racks to cool completely.
Makes 24 muffins.
