But first, let’s talk chocolate and peanut butter. It’s a classic pairing. I don’t know about you, but when there is a cookie tray for the holiday set out on a table, it seems the chocolate peanut butter desserts ALWAYS go first.


Or is it my imagination? Am I the only one wishing people would snatch those fruitcake slices and leave more brownies for me?

Some other classics?

National Lampoon’s Christmas Vacation.  Miracle on 34th Street (the original of course). White Christmas. A Christmas Story.

And of course, Yogi Bear’s First Christmas.

Yes, it’s by far my favorite Christmas cartoon! Have you seen it? I wish it would be shown every day during the holidays!

What are some of YOUR favorite holiday movies?

Love Actually, ELF, and Home Alone are always some of the most viewed in our house this time of year!

Let’s talk about those cookie trays? If you’re looking for a delicious dessert that will be the talk of the cookie exchange, trust me when I tell you to make these brownies!

The chocolate, fudgy brownies on their own are delicious. I added some Reese’s peanut butter morsels for that extra crunch in the brownies (tell me YOU love chocolate chips or PB morsels in your brownies too???).

I then topped these brownies with a light fluffy peanut butter frosting. If that wasn’t enough for you, the extra Reese’s peanut butter cups on top are sure satisfy that holiday sweet tooth!

Chocolate Peanut Butter Brownies
Prep Time 15 minutes
Cook Time 45 minutes
Rich, fudgy Brownies filled with peanut butter morsels and topped with a fluffy peanut butter frosting. Loads of chopped Reese's peanut butter cups make this the ultimate, classic holiday dessert!


For the Brownies:

  • 6 (1-ounce) squares unsweetened chocolate
  • 1 cup unsalted butter
  • 2 cup granulated sugar
  • 3 large eggs
  • 1 1/3 cup all-purpose flour
  • 10oz peanut butter morsels

For the Frosting:

  • 1/2 cup unsalted butter
  • 1/2 cup creamy peanut butter
  • 2 cup powdered sugar
  • 2 Tbsp skim milk
  • 24 Reese's peanut butter cups miniatures, chopped


  1. For the brownies, preheat oven to 325 degrees F. Line an 8inch square baking dish with parchment paper. Set aside.
  2. In a large microwave safe bowl, combine unsweetened chocolate with butter. Melt on high heat for 30 second intervals, stirring after each addition (about 90 seconds total).
  3. Add sugar and stir until combined. Add eggs, one at a time until fully incorporated. Mix in flour completely. Fold in the peanut butter morsels.
  4. Pour into prepared baking dish and bake for about 45 minutes. Remove from oven and cool completely before frosting. Brownies will be soft and fudgy! Refrigerate brownies before frosting to help them firm up!
  5. For the frosting, beat butter, peanut butter, powdered sugar and milk for 5 minutes using an electic mixer with whisk attachment on medium high. Spread over cooled brownies. Top with chopped Reese's peanut butter cups. Cut into bars and enjoy! Store in an airtight container for up to 3 days.
