Double Decker Butterfinger Brownies

Can we talk about being a mom when you’re sick?

It’s completely ridiculous, that’s what.  I get a horrible cold at least once every season, and every single time I swear that I don’t remember ever being this sick.

Until the next time.

I always start off in a kind of denial — the sore throat could just be allergies, right?  But deep down, I know that I’m getting sick, so I start trying to gently break it to my family.  Sniffles here and there…a “gee, I wonder if I’m getting sick” there…I don’t know why I even bother with such shenanigans.  Men and children aren’t so keen on subtlety, if you haven’t noticed.

Finally, when my sickness has reached the point that it feels like an Oompa Loompa has crawled inside my brain and is pounding my head with a mallet, when my nose is rubbed raw from tissues and I can barely see through the constant tears hindering my vision, I utter the dreaded words, “I’m pretty sure I’m sick.  I am.  I’m sick.  I feel like death, this is awful.”

Mic drop.

It’s like there’s this invisible filter that just picks those words out of thin air and keeps them from entering the boys’ ears.  I don’t know, I honestly don’t understand.  It’s like magic, except the opposite.  Like dark magic.  Straight up Voldemort nonsense going on around here.

One time I got really mad at my husband for ignoring my sickness and he told me it was because, “you always seem fine…you know…you’re doing things.”

By “doing things” he meant feeding the baby and changing diapers and making sure my son went to school.  You know, stuff you have to do so the government doesn’t take your kids away from  you.  What is this life, because I can’t even.

I’ve decided that instead of prison,  criminals should be given a sinus infection and forced to listen to Mickey Mouse Clubhouse while repeatedly filling sippy cups and bowls of Goldfish crackers.  If we had any repeat offenders, I’d truly be shocked.

Double Decker Butterfinger Brownies

So.  These brownies.  They look fancy, but they’re totally not complicated.  I love recipes like this that just take a couple basics and change them up into something super fun and decadent looking.  These are just my favorite homemade brownies (one bowl — it doesn’t get better), cut into squares, frosted with peanut butter frosting, sprinkled with crushed Butterfingers and stacked into double decker.  How lovely do these look piled on a tray?

Freaking fabulously lovely, that’s how.

To get your squares nice and even for stacking, just use square biscuit cutters.  My favorite trick for even squares all day long.


Double Decker Butterfinger Brownies


  • Brownies:
  • 1 cup (2 sticks) salted butter, melted
  • 1 cup unsweetened cocoa powder
  • 2 cups granulated sugar
  • 4 large eggs
  • 1 TBS vanilla extract
  • 1 1/4 cups flour
  • 1 jar hot fudge sauce (like what you use for sundaes)
  • Frosting:
  • 1 1/2 (12 TBS) sticks salted butter, at room temperature
  • 1/2 cup smooth peanut butter
  • 1 teaspoon vanilla
  • 4 TBS milk
  • 3 cups powdered sugar
  • 3 large Butterfinger candy bars, crushed


  1. Preheat oven to 350. Spray a 9×13 pan with nonstick spray ( I prefer to line mine with foil prior to spraying — it makes the brownies easier to remove) and set aside.
  2. In a large bowl, whisk together the cocoa and melted butter. Stir in sugar until combined. Stir in eggs, one at a time, mixing well after each. Stir in vanilla. Fold in flour JUST until you no longer see flour streaks in the batter. Gently fold in hot fudge sauce (you may need to heat it just enough to spoon/pour out of jar).
  3. Spread batter in prepared pan and bake for about 20 minutes. Brownies will look cakey on top and feel very dense — that is normal. Let brownies cool completely.
  4. Cut cooled brownies into even squares (you can also use a biscuit cutter) and set aside while you prepare frosting.
  5. In a large mixing bowl, beat butter, peanut butter, vanilla, and milk on medium-low speed until smooth. Slowly add powdered sugar, beating on low until just barely mixed in. Increase speed to medium high and beat for about 2 minutes.
  6. Frost 1/2 of the brownie squares generously, (I used a piping tip, you can also just use a knife), then sprinkle with crushed Butterfinger. Top with another brownie square and repeat process.


Yields about 6-8 large double decker brownies. Keep uneaten brownies stored in refrigerator.

These brownies are definitely for showing off — no one has to know how easy they are.

I hope you love them as much as I do.  Have a happy Monday!
