Preheat the oven to 350°F. While the cooker’s getting ready, this warms up all the ingredients and makes baking smoother.
Cream together butter, cookie butter, brown sugar, and granulated sugar in a bowl. Y’all wanna get a nice smooth mix with no lumps.
Beat in the egg and vanilla extract until it’s all well combined. The batter will look shiny and kinda thick now.
In another bowl, whisk flour, cornstarch, baking soda, and salt. This dry mix is the backbone for your cookies’ texture.
Slowly mix the dry into the wet ingredients until just combined. Don’t overdo it or the cookies might turn tough.
Scoop out dough portions, flatten in your palm, then add a tablespoon of cookie butter in the center. Wrap the dough around it and roll it ball-shaped evenly.
Place dough balls on a parchment-lined baking sheet, spaced well apart so they’ve room to spread. Bake 10-12 minutes till edges hold but center stays soft.
Once out, drizzle extra cookie butter on top for that glossy biscoff finish. Let cookies cool for a few minutes on sheet before moving to a wire rack.
Notes
Enjoy with a glass of milk or your favorite tea. Store in an airtight container to keep them soft.
