Candy Bar Brownies

Thick and chewy Candy Bar Brownies are topped with a chocolatey layer of Reese’s, Butterfingers, cocoa Krispies, peanut butter, and more!

Use a box mix, or make a batch of Homemade Brownies for the base of this rich dessert. It’s thick and layered, similar to our Cheesecake Brownies and Double Fudge Brownies.

Do you like brownies?

I admit the hubby isn’t a huge fan, but he definitely loved these Candy Bar Brownies I’m posting about today because they’re brownies taking to a whole new lebvel!

I mean – what’s not to love about a thick layer of chocolate-y goodness which includes Reeses’s, Butterfingers and LOTS of chocolate chips! 😉

Can you go wrong with candy like that thrown on top of brownies? NOPE!

We served these up with ice cream, but they’re definitely a great stand-alone dessert as well. If you like LOTS of chocolate-y deliciousness then you must give these guys a try. I promise they won’t disappoint. 😉

Brownie base for candy bar brownie recipe

Two Layers of Goodness

These brownies are made up of two chocolatey layers. 1) A brownie base and 2) a peanut butter chocolate mixture chock full of candy bars.

BASE. You can use any store-bought box mix for the brownie base, or you can use our favorite homemade brownie recipe. Bake until slightly underbaked, add chopped candy bars and bake an additional 4-6 minutes.

MELT. Melt your chocolate chips, butterscotch chips, and peanut butter until smooth. Stir in your cocoa pebbles.

SPREAD. Remove brownies from the oven and spread your cocoa pebbles mixture over top.

CHILL. Refrigerate for at least 2 hours before serving. These brownies are best eaten cold.

Serving: One good thing about these being ultra rich is that you only need a small piece to get your fill. This makes them great mini treats to serve at parties. Simply cut the brownies into small pieces and place each piece in a mini cupcake liner. 

I also suggest having milk on hand to wash down the decadent treat!


This dessert is already full of delicious chocolate. Of course you can always add more or even substitute with your favorites. Some ideas include: Reese’s Pieces, mini M&M’s, Kit Kat, chocolate or peanut butter chips.

Storage Tips

STORE in an airtight container for up to 3 days. You can store these at room temperature or in the refrigerator, but we recommend keeping them in the fridge since the top layer is best cold.

To FREEZE for later, cut the brownies into squares. Wrap each brownie with plastic wrap and place them in a freezer Ziploc, or you can wrap them again with foil. Freeze for up to 3 months. Thaw before eating.

  1. Hi Krystin,
    I would like to bake the delicious Bomb Brownies, but I have a problem. Here in Austria we don’t have boxes of Brownie Mix. Because you wrote that one can use also homemade Brownie Mix, I would like to ask you, if you can give me the homemade recipe. That would be great!
    Best greetings from Vienna,

    The best dessert around! Love the short cup on using boxed brownie mix! The second layer was even better with all of the candy!
