cookie butter chocolate chunk blondies

Studded with chocolate chunks, cookie butter chocolate chunk blondies make the best anytime treat!

I’m never not in the mood for a blondie. The buttery golden bars are easily made whenever a whim strikes (the batter is a 10-minute, one-bowl affair), and also easily customized to every impulse. In this instance, cookie butter and chocolate chunks steal the show; cinnamon and nutmeg enhance the cookie butter flavor even further.

Cookie Butter Chocolate Chunk Blondies

Studded with chocolate chunks and cut into hearts (a Valentine’s treat!), these blondies are especially compelling when slightly warm. Think of this recipe as a template for your own whims – dip each blondie in chocolate, swap in peanut butter or Nutella for the cookie butter, add a handful of white chocolate chips or toffee bits, top the bars with flaky sea salt… blondie bliss is well within your reach.

  • 1/4 cup unsalted butter, melted and slightly cooled
  • 1/4 cup cookie butter, melted and slightly cooled

  • 1 large egg, at room temperature
  • 1 tsp vanilla extract
  • 1/4 tsp cinnamon
  • pinch of nutmeg
  • 1/8 tsp salt
  • 1 cup flour
  • 1/4 cup semisweet chocolate chunks


  • 2 Tbsp semisweet chocolate chunks


  1. Preheat oven to 350°F and line an 8-inch square baking pan with parchment paper.
  2. Combine melted butter, cookie butter, brown sugar, egg, vanilla, cinnamon, nutmeg, and salt in a medium bowl; whisk until smooth. Fold in flour just until incorporated, then fold in chocolate chunks. Scrape batter into prepared pan and and use a piece of parchment paper lightly coated with nonstick spray to press evenly into pan. Top batter with chocolate chunks, pressing gently to adhere.
  3. Bake for 22 to 24 minutes, until top is set, edges are golden, and a toothpick inserted in the center comes out clean or with a few crumbs attached. Cool completely in pan on a wire rack.
  4. Just before cutting, chill in the freezer for 10 minutes. Carefully lift parchment to remove bars from pan and place on a cutting board; use a small heart-shaped cookie cutter to punch out hearts or cut into squares with a sharp knife.

  1. Laura, these look seriously insanely amazing! Love those chocolate chunks and yay for those cute hearts 🙂 Pinning!

  2. Where is my jar of cookie butter lurking in the cupboard when I need it!! These look SO GOOD. I might just have to make a special trip to the store this afternoon for these ingredients.

  3. Chocolate is a must for Valentine’s Day. These blondie’s would make my special someone, very happy!

    1. Hi Pam, cookie butter is a spread (like peanut butter) made from Speculoos cookies. You can find it at Trader’s Joes, or look for it under the name Biscoff spread at your grocery store. Hope that helps! 🙂

  4. Scrumptious! If I can resist spooning cookie butter straight from the jar, I’ll definitely be making these blondies.

  5. What a fun, unique and delicious twist on traditional blondies. I love that you cut them in heart shapes too!

  6. Deliciousness! I don’t know anyone who doesn’t like Cookie Butter. Like you, Laura, I can never turn down a Blondie and these look superb cut into little heart shapes. Perfect sweet treat for Valentine’s Day!

  7. These would make the family VERY happy on Valentine’s Day!! The addition of cookie butter pushes these gems over the top!

  8. I’m a huge blondie fan, too Laura and these are perfect. Love the cookie butter addition!

  9. These look so tasty! I keep hearing about the wonders of cookie butter – I think I need to pick some up soon!

  10. STUNNING brownies, Laura! Your photos are perfection, as always, and I love how you cut them into little hearts. The cutest. <3

  11. These are amazing, Laura! Such a wonderful treat for the Valentine’s. And I love the chocolate chunks very much!

  12. I’m in love with your blomdies. I’m pinning it as I definitely want to make them.

  13. Baked these yesterday. They were soooo tasty!! I’m going to bake more today. Thank you so much for the recipe!!!

  14. What if you cut them into hearts before you bake them? You would lose less batter and they’re easier to cut I think. Would you bake for the same amount of time? Also, I was wondering, what if I wanna put mashmallows inside? Would I bake them for the same amount of time? Thank you for the idea.

    1. Hi Emilia, I don’t recommend that. Blondie batter is different from cookie dough and needs the support of the pan to bake, plus the hearts would likely not retain the shape during the baking process. Adding some mini marshmallows should work fine, baking time will be about the same.
