Heavy Whipping Cream

See recipe card for quantities.

Instructions

Step 1: Preheat the oven to 350 degrees and generously spray an 8x8 baking pan, preferably glass. Add both sugars and the cocoa powder to a medium saucepan and stir until smooth. Remove from heat once fully combined.

Step 2: Then, transfer the chocolate mixture to a large mixing bowl. Add the vanilla and eggs and mix until smooth and well combined.

Step 3: Gently fold in the flour and cornstarch until no dry spots remain.

Step 4: Spread the batter evenly into the prepared pan and bake for 22 to 25 minutes. The brownies should look set but still wiggle slightly in the center when you gently shake the pan.

Step 5: While the brownies bake, prepare the icing. Add the heavy whipping cream and chocolate chips to a small saucepan and heat over low to medium heat, stirring until melted and smooth. Do not let the mixture boil.

Step 6: Once the brownies finish baking, let them cool completely in the pan. Pour the icing over the top and spread evenly. You can keep this on low/warm until you are ready to use it.

Step 7: Finish by adding your topping of choice (candy, sprinkles, etc) then chill the brownies for about 1-2 hours before slicing and serving. Enjoy!

FAQ

How do I know when the brownies are done baking?

The edges should look set, while the center still moves slightly when you gently shake the pan. This jiggle ensures a gooey, fudgy texture once the brownies cool.

Can I change the topping?

Yes, this recipe works perfectly with different toppings. Swap the candy for holiday sprinkles, themed colors, chopped candy bars, or festive mixes to use this recipe year round.

Do I need to let the brownies cool before adding the icing?

Yes, let the brownies cool completely in the pan before icing. Cooling helps the topping spread smoothly and prevents it from melting into the brownies.
