Mocha Twix Brownies

Mocha Twix Brownies are not responsible.

They don’t care about you, and I hate to say that they aren’t gonna leave you better off than when they found you. But I can promise you one thing:

Mocha Twix Brownies are the best irresponsible thing you will ever do… that involves a brownie!

These aren’t fancy. I’m gonna be up front here and say that these are boxed brownie mixes. Boxed brownie mixes made in the most decadent way imaginable. How about a story?

When I was pregnant with my son Wyatt, my aunt June made some insane brownies for me with Symphony candy bars layered in the middle. I say “insane”, but a better word for those naughty little devils would be “inspiring”. Those brownies got this hungry pregnant lady baking batches of brownies like crazy! On a side note: my aunt June is always cooking, canning, and baking for everyone in her life. She does it to make them feel better, to keep them from hunger, or to make them feel loved. Whatever the reason, she’s persistent with her delicious cooking, and I love and admire her for that. Anyway… I decided that if Symphony bars were awesome, then how would other candy bars taste?

I must have tried everything. Let’s see: Kit Kat, Snickers, Reeses, Rolos, Heath Bars, York Peppermint Patties (which are the correct choice for Christmas gifts), and then I tried Twix.

It’s crazy. Twix aren’t even my favorite candy bar. If I had a gun to my head (which would be outrageous for someone to get that violently worked up over candy preference, but O.K. I’ll play along) I’d have to pick PayDay. But the chewy caramel, crunchy cookie, and fudgey brownie combo was just over-the-top-arm-wrestling perfect… or so I thought.

I never considered putting this recipe on my site because, let’s be honest, it’s not really a “recipe”. You layer candy bars inside brownie batter. But spreading Ree Drummond aka The Pioneer Woman aka the Queen of all food bloggersmocha frosting over the Twix Brownies… it was borderline life changing.

Ok so maybe I’m dramatic. But I’m also a serious dessert eater, and I know good from great… and these are beyond great!

Mocha Twix Brownies Recipe



  • 2 boxes Brownie Mix (I used Betty Crocker Fudge Brownie Mix)
  • 30ish fun size Twix (This is not an exact science.)


  • 1 stick unsalted butter (softened)
  • 2 1/2 cups powdered sugar
  • 1/4 cup cocoa powder
  • 1/8 teaspoon salt
  • 1 1/2 teaspoon vanilla
  • 1/4 cup coffee (cooled)


Step 1
Prepare your brownie mixes according to their package directions, including preheating your oven to the required temperature. For mine, it was 350 degrees.
Step 2
Spray a 13 x 9 pan (I used a glass pan here) and pour roughly half of your brownie batter into the greased pan.
Step 3
Gently lay an even layer of Twix over the batter. Pour over the remaining batter, trying to completely cover the candy bars.
Step 4
Bake until the center of the brownies don't seem to jiggle when tilting the pan. My brand of brownie mix called for baking one box of brownies for 20-24 minutes. We're dealing with two boxes worth of brownies plus an entire bag of fun size Twix here because we're either insane or enjoy flirting with the threat of diabetes. Anyway, I baked mine for 45-50 minutes (it was a team effort so we had trouble remembering the exact timing.)
Step 5
To make the frosting, add the softened butter, sugar, cocoa powder, salt, and vanilla to the bowl of a stand mixer. Begin to mix on the lowest speed until it seems to become less powdery and more like clumps.
Step 6
Slowly pour in the coffee until you're sure the contents of the bowl aren't going to fly out at you and then let it rip. Crank the mixer up to high and whip the hell out of it until it's completely fluffy and a yummy light brown color.
Step 7
Spread the frosting evenly over the slightly or completely cooled brownies. I had ants in my pants to get these in the fridge to set, so my brownies were still a little warm when I added the mocha goodness. It didn't seem to make such a big difference. The butter in the frosting started melting just a bit, but not enough to cause problems. As long as you're popping it in the fridge to set, the main thing is getting that yummy layer all over the top.
Step 8
When you're ready to get crazy with some decadence, make sure to run your knife under hot water and wipe dry in between each cut. This should ensure that you get nice clean slices and keep the frosting from gooping up on your knife.
Step 9
Here's another picture of the same stack of brownies just because I couldn't stop taking pictures... or eating them.
Step 10
Seriously. Please make these, and let me know if you survived eating the whole pan!

    I am dying to make these (bc Twix ARE one of my favorites), but I know I cannot because I will not have an ounce of willpower.

    Ashley, I made these for the sake of “the site” and then ended up eating most of the pan over the course of a week… I will not be making these again unless I’m delivering them as a gift! They are the devil!
