ingredient notes & substitutions

ingredients needed to make cookie butter brownies.

Biscoff spread: Also known as cookie butter! You can find this in most grocery stores, Amazon, and Trader Joe’s (as Speculoos Spread). I tested these Biscoff brownies with all of them and any brand will work. You can also use crunchy cookie butter instead of creamy!

Brown sugar: Light brown sugar and dark brown sugar can both be used.

Cocoa powder: Unsweetened Dutch cocoa powder is key to ultra-rich and fudgy brownies. My favorite brand to use is Ghirardelli!

Espresso powder: If you’ve made my chocolate coffee cake, you’ll know that adding espresso to chocolate intensifies the richness and flavor of the chocolate. While optional, I highly recommend adding it!

Egg yolk: The extra egg yolk brings richness and moisture, resulting in extra gooey brownies, similar to my birthday brownies!

Chocolate chips: I prefer semi-sweet chocolate chips but you can also use dark chocolate chips.

recipe instructions

Before you start, line a square pan with parchment paper and preheat the oven to 350 F/180 C.

Step 1: Freeze the Biscoff layer. Press a large piece of parchment paper into the baking pan and crease the bottom edges so when you take it out you can see the outline of the size of the pan.

Evenly spread the cookie butter inside the creased edges, then chill it in the freezer until firm. I recommend waiting until completely firm before starting the batter!

expert baking tips

  • Use a kitchen scaleBaking with a scale is much more accurate than cup measurements. To convert this recipe, click the “metric” button next to the ingredients title on the recipe card. If you do not have a scale, use a spoon to fluff the flour first, then spoon it into your measuring cup.
  • ​Make sure the layer of Biscoff is completely firm before using, otherwise, it will stick to the parchment paper and it won’t come off!
  • Use a metal pan, not a glass or ceramic one! Glass or ceramic pans retain heat differently. A pan with rounded edges or one that is not metal will have a longer bake time.
  • To achieve a crackly top, make sure to whisk together the eggs and sugar until it starts to lighten in color. This should take about 1 minute!
  • Wait until the brownies are cool before cutting! They will be a gooey mess making it impossible to cut them when warm.

storage & freezing

Store leftover Biscoff brownies in an airtight container for 2-3 days at room temperature. To keep them from drying out, don’t cut the whole pan all at once, just as needed.

Once baked, you can freeze the brownies in an airtight container or freezer bag for up to one month!

recipe faqs

How do I know when Biscoff brownies are done baking?

The pan should not jiggle when they are done baking. You can also stick a toothpick into the center and pull it out. If it comes out covered in a few moist crumbs, they are done baking. The toothpick should NOT come out clean, otherwise, they are over-baked.

Where can I buy Biscoff?

You can find Biscoff near the peanut butter and jam at the grocery store. You can find it at Walmart, Amazon, Trader Joe’s, and most local grocery stores!

What is Biscoff made of?

Biscoff is a peanut butter-like spread that is made of Speculoos cookies! The cookies are buttery, brown sugar cookies with a warm-spiced flavor similar to gingerbread.

What is the best way to cut brownies?

Wait until the brownies are completely cool, this could take a few hours. Once cool, run a sharp knife under hot water and wipe it clean in between cuts. You should have perfect clean-cut brownie squares!

Notes

*Measure your flour properly. This is my #1 baking tip! Do not ever scoop a measuring cup into your flour as this always leads to using too much flour. Instead, use the spoon-level method. This means fluffing the flour first, then spooning it into your measuring cup/spoon. For the BEST results, use a kitchen scale!*
