Easy Bat Brownies

Looking for a fun treat to make with the kids for Halloween? Look no further! These bat brownies are so fun to make! You can easily decorate chocolate muffins or chocolate cookies to look like bats, but today we’re decorating brownies.

Use boxed brownie mix or make your own—either way, these will turn out cute! I’ll share my brownie recipe below. They are fudgy and delicious—just like cosmic brownies.

After the brownies have been sliced into squares you’ll add candy eyes and Oreo cookie bat wings to the top of the brownies!

Brownies

1/2 cup butter, melted
1 cup sugar
1/4 cup brown sugar
2 large eggs
1 teaspoon vanilla
2/3 cup flour
1/3 cup cocoa powder (I prefer Hershey’s Special Dark)
1 teaspoon salt

Glaze

12 oz. bag of semi-sweet chocolate chips
4 Tbsp. butter
2 Tbsp. honey (or light corn syrup)
2 Tbsp. milk

Decorations

12-16 Oreo cookies (you only need 10, but sometimes they break when you cut them so it’s a good idea to have a few extras)

candy eyes

HOW TO MAKE Halloween Bat BROWNIES

Preheat the oven to 350 degrees.
Prepare a 9″x13″ baking dish with parchment paper and spray with nonstick cooking spray.
Note: You’ll want to leave an inch or two of parchment paper over the edge on each end so that you can lift the brownies out of the pan later on.
In a large mixing bowl mix melted butter, sugar, and brown sugar. Mix until creamed and smooth. This can be done by hand (with a Danish dough hook) or with an electric mixer on low speed until just combined.
Add eggs and vanilla. Mix.
Add flour, cocoa powder, and salt. Mix.
Pour brownie batter into the prepared baking dish. Spread with a rubber spatula.
Bake brownies for 20-22 minutes. Brownies may seem undercooked, but that is fine. They will continue to bake in the pan while it cools.
Let brownies cool for 20 minutes (they’ll still be warm). While they sit, make the ganache.
Combine ganache ingredients and melt on the stovetop over med-low heat OR in the microwave in 15-20 second intervals, stirring in between each interval until melted and smooth.
Pour ganache over warm brownies and spread until smooth.
Let brownies sit for 1 hour at room temperature then chill for 1 hour in the refrigerator. The glaze should be set enough to slice, but soft enough to still press the decorations into it.

13. Lift the brownies from the pan, using the parchment paper, and set them on a cutting board. Use a sharp knife to trim the edges and slice them into 20 squares.

How To Decorate Bat Brownies

Separate Oreo cookies, scraping out the filling. Cut the cookies in half using a sharp knife. Some may break, but if you have a few extras you’ll be just fine.
Press 2 candy eyes and 2 Oreo wings into each brownie.

Store brownies at room temperature in an airtight container or cover them with plastic.
