Peanut Butter Cup Crunch Brownies

Sunday, June 3, 2018
Peanut Butter Cup Crunch Brownies are like a little slice of heaven for a chocolate peanut butter lover from Serena Bakes Simply From Scratch.

These are Peanut Butter Cup Crunch Brownies are sooo naughty..

I mean really naughty almost like we shouldn't talk about it naughty..

They call these Better Than Crack Brownies but for the sake of my daughters own embarrassment we are calling them Peanut Butter Cup Crunch Brownies or a Little Slice Of Heaven works too.

She thought a Little Slice Of Heaven was a much better name for these.

The whole family thought I was really finally losing it when I said were making Better Than Crack Brownies. 

The two oldest looked at me and said, "What kind of name is that?" 

I said,"I don't know but they sound good to me!"

Who knew a name would be such a big deal.

The family all pitched in making these and Colt looked at me like I was crazy when I explained what we were doing..

The kids all had a brownie, and then left for a few days to Colt's sister house..

The following is our tail of events..

We sat, while Colt sat and I laid on the couch, started watching Mad Men, and eating Peanut Butter Cup Crunch Brownies with Vanilla Ice Cream.. Over the next 3 nights while the kids were gone.

These are dangerously good.


Grease and line a 9 x 13" baking pan with parchment paper. Butter parchment paper well.

Peanut Butter Cup Crunch Brownies add butter, chocolate chips, and melt.

Add 1 1/2 cups Butter, and 1 1/2 cups Semisweet Chocolate Chips to a small saucepan and cook over medium-low heat, stirring until chocolate melts. 

Remove from heat and set aside.

Stir in 1 cup Brown Sugar, 1 cup Granulated Sugar, and 1 teaspoon Salt, until sugar is dissolved. 

Allow mixture to rest for 5-10 minutes, until close to room temperature, so eggs don't curdle.

Whisk in 6 whole Eggs, 1 at a time beating well between each addition. Stir in 1 teaspoon Vanilla, until well combined.

In a small bowl whisk together 2/3 cup Dark Chocolate Cocoa Powder, and 3/4 cup All-Purpose Flour or Whole Wheat Pastry Flour, until well combined.

Whisk flour mixture into melted chocolate mixture.


Spread Fudge Brownie in parchment lined pan and bake brownies for 40 minutes.


Here's where we get naughty.. Remove brownies from pan and sprinkle with chopped Peanut Butter Cups.

Pop Peanut Butter Cup Brownies back into the oven for 5 more minutes. (No we aren't done yet, it gets better.)


Melt chocolate chips, crunchy peanut butter and butter over medium heat until chocolate is melted and mixture is well combined. 

At this point it's a good idea to keep a second wooden spoon on hand to smack anyone who comes near your bowl, I learned this the hard way. I found Colt and all 3 kids taking turns dipping there fingers in.. I couldn't believe what I saw. 

Taste testing should be reserved for me, what were they thinking.


Stir in Rice Crispy's or Cocoa Crispy's into the melted peanut butter/chocolate mixture. 

We used Envirokidz Organic Chocolate Koala Crisps since it's the cereal we buy for the kids and it worked great! (They haven't sent me product or paid me to use their name this is my own personal opinion.)


Spread chocolate, peanut butter, crisp mixture over the top of cooked brownies with peanut butter. 

Place in refrigerator 2 hours before serving or 45 minutes to an hour in the freezer until chocolate sets.

Cut to desired serving size and serve with Ice Cream if you're feeling extra naughty. 

These are extra rich so I suggest small slices.

  12. Do you have to use all-natural peanut butter?

  13. This looks SO decadent! Are those the full-size pb cups (as opposed to the foil-wrapped miniatures)?

  14. Do you use a 9x13 pan or a 9x9 pan?? In the pictures you show a 9x9 but the instructions call for a 9x13.

    1. Hi, The photos probably deceiving because that is a 9"x13" pan. I hope that helps, Serena

  15. Do you use light brown sugar? Making them for Father’s Day.

    1. Yes, Usually just the golden brown or light but not dark. I hope that helps, Serena

  16. Can I cut the sugars in half? I stead of 2 cups of sugar make it 1 in total?

    1. You could but I don't know what it will taste like. I've never tried it to know. Thanks, Serena
