How to Store Brownies

Whenever you make double chocolate brownies with chocolate buttercream frosting, you want to make sure you store it in an airtight container. If the brownies are left uncovered, they will get dried out and become hard. You can also store the double chocolate brownies in a freezer bag.

Can Double Chocolate Brownies be Frozen

I love putting desserts in the freezer. It is a great way to have desserts on hand whenever the craving hits or when unexpected guests come to the house. Double chocolate brownies with chocolate buttercream frosting make a great freezer dessert.

When you are ready to freeze these brownies, you will want to freeze them on a plate or something similar before you freeze them in an airtight container. This lets the frosting freeze and get hard before the brownies are stacked on top of each other.

Once the brownies are frozen, move them to an airtight container or freezer bag. I like to keep parchment paper between the layers to make it easier to remove the brownies when I am ready to serve them. Let them thaw at room temperature before serving.

Variations to Chocolate Brownies

I love topping these brownies with homemade chocolate buttercream. It makes an incredibly rich brownie. Then I add sprinkles and M&Ms. You can change up the brownies for something slightly different, like adding chocolate chips or white chocolate chips. Here are a few more suggestions to try.

  • Reese’s Peanut Butter Cups– If you love peanut butter cups, you can swap the M&Ms for chopped peanut butter cups. If you want a bigger peanut butter cup flavor, you can also add chopped up peanut butter cups into the batter.
  • Different M&Ms– There are so many different types of M&Ms out right now, from caramel to hazelnut spread to pretzels to peanut butter. Each M&M you put on top of these brownies will slightly change the taste. The change can create a whole new dessert to share with friends and family.
  • Vanilla Buttercream– You can also make vanilla buttercream instead of chocolate. Some people prefer vanilla over chocolate.
  • Mint Buttercream– You can keep with the chocolate theme and add mint extract to the buttercream. This creates a chocolate mint brownie. Then use mint M&Ms on top of the double chocolate brownies. You can also add mint into the brownie batter for a stronger mint flavor.
