Biscoff Cookie Butter Bars with Biscoff Frosting

There is so much wonderfulness in the title of this post that I don't even know where to start. Just uttering the word "Biscoff" makes me giddy. I've admitted before to having a self control issue with cookie butter - I cannot, and I repeat, CANNOT have it in my house without destroying the entire jar in one go. But these frosted speculoos cookie butter bars from Butter Me Up Brooklyn were haunting my dreams. Literally - I can't even remember how many times I've flipped to this recipe in my binder of "to make recipes" and sighed deeply and wished that I could be trusted around a jar of cookie butter. I don't even remember what the occasion was - or if I just made one up - but I decided that these bars NEEDED to be made and I NEEDED to eat them. I mean, come ON!! Biscoff FROSTING?! Are you kidding me?!!! Biscoff!!! I want to eat all the Biscoff things!! And these bars are no exception. HOLY SHNIKES they're good. The frosting is good enough to eat on its own - it's dangerous. My friends and I devoured these bars - they're other worldly. The bars themselves have a dense, gingerbread-y type thing going on, and the frosting is a fluffy, cookie buttery, sweet, Biscoff-y heaven. But oddly enough, they're not tooth achingly sweet - you know how sometimes buttercream frosting makes your teeth hurt? Not these guys. Basically they're perfect and wonderful and delicious and trust me - you want to eat them. And so you do your friends.


Biscoff Cookie Butter Bars with Biscoff Frosting

adapted from Butter Me Up Brooklyn

makes 16 bars


cinnamon sugar sprinkle:

  • 1 Tbsp granulated sugar
  • 1/2 tsp ground cinnamon

for the bars:

  • 1 1/4 cup all purpose flour
  • 1/2 tsp baking powder
  • 1/2 tsp baking soda
  • 1/2 tsp salt
  • 1/2 tsp ground cinnamon
  • 4 Tbsp unsalted butter, melted
  • 1/2 cup granulated sugar
  • 1/2 cup light brown sugar
  • 1 tsp pure vanilla extract
  • 2 large eggs
  • 1/2 cup Biscoff cookie butter

for the frosting:

  • 2 Tbsp unsalted butter, softened
  • heaping 1/3 cup Biscoff cookie butter
  • 2 cups powdered sugar
  • 5 Tbsp half & half


  1. Preheat the oven to  375 degrees. Line an 8x8 baking pan with parchment paper - use 2 pieces, one placed horizontally and one placed vertically, so they overlap. 
  2. In a small bowl, mix together the sugar and cinnamon for the sprinkle. Set aside.
  3. In a medium bowl, whisk together the flour, baking powder, baking soda, salt, and cinnamon.
  4. In another medium bowl combine the melted butter with the sugars, mixing thoroughly. Add vanilla and eggs and mix until well incorporated. Add the cookie butter and mix until smooth. Add the flour mixture to the cookie butter mixture and stir until just combined. Spread the batter into the prepared baking pan and smooth the top with an offset spatula. 
  5. Sprinkle the cinnamon sugar sprinkle evenly over the batter. Bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean. Let cool in the pan completely before cutting or frosting (if you want to transport the bars, do like I did and leave the cooled, uncut bars in the pan and frost them right in there, cutting into bars once you reach your destination - OR - remove the cooled uncut bars from the baking pan, frost, and cut into bars). 
  6. While the cookie bars are cooling, make the frosting. In a medium bowl beat together (I used an electric hand mixer, but a stand mixer will work just fine) the softened butter, cookie butter, and powdered sugar until well combined and smooth. Stream the half & half into the frosting mixture and continue beating on high, until your frosting reaches desired consistency (I like mine light and fluffy, so I beat it for about 5 minutes). Use an offset spatula to frost the bars.

this recipe is dangerous... I might just have to make it ;-)'s so good. I tell myself that if I bake the Biscoff into a treat I can share, it's safer than having the jar in my kitchen. I have seriously considered sneaking downstairs for a spoonful when I've woken up in the middle of the night!
