Best Biscoff Tres Leches Recipe

Once upon a flight back home, I had my first-ever Biscoff cookie. It changed my life—true story. The unique Belgium biscuit, commonly served as a snack on airplanes, has such a deep caramelized flavor that just pairs perfectly with the cozy holiday season. So I thought, Why not not make one of my favorite types of cakes with it? Tres leches (“three milks” in Spanish) cake is such an iconic Mexican dessert. It’s always my family’s go-to order for birthdays and other holiday celebrations. The local bakery we order from fills the cake with different fruits or, my favorite, dulce de leche. So one thing led to another: combining a delicious tres leches cake with the caramelized Biscoff cookies as the perfect dessert!

I hacked this recipe a bit by using boxed cake mix for the batter. I wanted to avoid the extra steps of having to make and fold in egg whites. But if you’d like to use a traditional batter, check out our tres leches recipe.

Of course, I’ve included the cookies themselves in this recipe, but I also wanted to use Biscoff Cookie Butter, also known as Speculoos, which is a creamy spread made of these Belgian spiced cookies. I use it in the milk mixture so that the entire cake is infused with the flavor, as a thin layer on the cake, and drizzled over the top for good measure!

This cake requires a little love and patience, but the result is so worth it. The longer it sits in the fridge, the more it can absorb the milk mixture, making the cake better and better. So make sure you’ve set aside some time to ensure the best results. I suggest making it a day before you plan on serving, and just top and assemble the day of! Did I mention it looks gorgeous? Everyone at your holiday party will be raving about it—trust me.

The cake can be made 3 days ahead. Cover with plastic wrap and refrigerate, or store individual slices in an airtight container and freeze up to 1 week. You can let it defrost or enjoy frozen straight out of the freezer.
