These Biscoff butter cookies really take the cake (or should we say, the cookie?). Biscoff spread gives the cookies a rich, caramelized flavor with a hint of cinnamon. And the Biscoff buttercream gives them a gourmet finish.

Add the butter, brown sugar, and granulated sugar to a large mixing bowl. Mix on high speed until light and fluffy. Mix in the Biscoff cookie butter.
Add the egg and egg yolk one at a time, beating well between each addition. Beat in the vanilla until well combined.
Place a sifter over the mixing bowl and sift the flour, salt, cinnamon, baking powder, baking soda, and cornstarch over the batter. Stir the dry ingredients into the batter until well combined. Stir in the crumbled cookies and white chocolate chips.
Use a large ice cream scoop to make giant balls of cookie dough (see notes if you want to make smaller cookies). Place the dough balls on a plate or a baking sheet and transfer them to the fridge for 4 to 6 hours.
Preheat the oven to 375°F and line two baking sheets with parchment paper.
Place the chilled cookie dough balls on a baking sheet, spacing them at least 2 inches apart.
Bake for 9 to 12 minutes or until golden brown on the edges. Let them rest on the baking sheet for 10 minutes before transferring them to a cooling rack.
Make the Buttercream
Place the butter in a mixing bowl and beat on medium speed until smooth and creamy.
Stop the mixer and add the powdered sugar. Start the mixer on low speed and gradually increase the speed to medium-high. Mix until well combined.
Add the cookie butter, vanilla, cinnamon, and salt. Mix until well combined.
If the buttercream looks too stiff, add the heavy cream 1 tablespoon at a time mixing well between each addition.
Spread the buttercream on top of the cookies. If you have extra Biscoff cookies, use them to decorate the buttercream cookies.
Notes
If you want to make smaller cookies, use a 2 tablespoon cookie scoop and reduce the baking time to 8 to 10 minutes.
