How to Make Biscoff Blondies

Make the blondie batter

The batter starts by combining melted butter, cookie butter spread, granulated sugar, and brown sugar. The melted butter and brown sugar both help give the blondies their classic chewy texture. Add eggs and vanilla extract, followed by the dry ingredients. Finish the blondie batter with white chocolate chips.

Add to pan

Pour the batter into a 9”x9” baking pan that is lined with parchment paper. I like to create a sling with the parchment that goes up the sides of the pan so the blondies can easily be lifted out of the pan. Use an offset spatula to evenly smooth out the batter in the pan.

Top with cookies

Crush Biscoff cookies into pieces and lightly pressed into the top of the biscoff blondie batter. This gives the blondies a nice crunch and shows off the flavor of the blondie.

Bake

The blondies bake at 350°F for 30-35 minutes. The blondies should be slightly soft and gooey so be sure not to overbake the blondies. A toothpick inserted into the middle should come out with a few wet crumbs, not wet batter but not completely clean.

Drizzle cookie butter

Once the blondies are out of the oven, drizzle more melted cookie butter spread over the top. Cut into squares and enjoy!

Blondie FAQs

What is Biscoff?

Biscoff is a popular brand of cookie butter spread, made with ground Biscoff cookies which have a unique cinnamon-spiced, caramelized flavor. Other brands make their own cookie butter spread, such as Trader Joe’s Speculoos Cookie Butter. These spreads are all very similar with a creamy peanut-butter-like consistency. The flavors of the cookie butter perfectly complement desserts, like my Mini Biscoff Cheesecakes.

What is the best way to store the blondies?

Store the biscoff blondies in an airtight container or zip-top bag at room temperature for up to 3 days.

Can I freeze the blondies?

Yes, blondies freeze very well! Store the cooled blondies in a zip-top bag or airtight container in a single layer. To thaw, pull from the freezer the night before or several hours before serving and allow to come to room temperature.

What size pan is best?

I prefer to use a 9”x9 square metal baking pan. You can use an 8”x8” pan but the blondies will be thicker and will need more baking time. I recommend using a metal pan, as it will distribute the heat better and help the blondies bake more evenly than a glass or ceramic pan.

How do I know if the blondies are done baking?

The blondies should be golden around the outer edges and just set in the center. Blondies are meant to be chewy and slightly gooey in the middle so be careful not to overbake them. A toothpick inserted should come out with a few moist crumbs, but not wet batter.

Baking Tip: Weigh Your Ingredients!

I highly recommend using a kitchen scale to weigh your ingredients rather than using measuring cups because it is the most accurate way to bake. Weighing your ingredients will give you more consistent results with your recipes and a better success rate, every time. Using a scale also saves you dishes which means easier cleanup! I provide gram measurements in all my recipes and this is the scale I love to use.

  1. My understanding of true blondies is that they typically only use brown sugar and no white — how would the texture of this bake be affected if I used only brown sugar (as in, 300gr brown sugar instead of 200 brown + 100 white)?

    1. Hi Lyn, you could definitely swap out the granulated sugar for brown sugar instead. I’m not sure it would be very noticeable in this recipe but typically brown sugar adds more chewiness and molasses flavor.
