1-First Step: Mise en place and mixing the wet ingredients Gather and measure all ingredients before you start. This helps the process move smoothly and keeps the texture of the dough consistent. Preheat nothing yet; first prepare the dough. In a large mixing bowl, combine the 4 oz unsalted butter (melted and cooled), 1/2 cup cookie butter, and 3/4 cup light brown sugar (lightly packed). Cream them together until the mixture is light, glossy, and creamy. This step builds the base flavor and integrates the cookie butter evenly.

2-Second Step: Add egg and vanilla Add 1 large egg (room temperature) and 1/2 teaspoon pure vanilla extract to the bowl. Beat until the mixture is fluffy and slightly aerated. Room-temperature egg blends more easily and produces a more consistent dough texture.

3-Third Step: Combine dry ingredients In a separate bowl, sift together 1 1/4 cups all-purpose flour, 1/2 teaspoon baking soda, 1/4 teaspoon baking powder, and 1/4 teaspoon kosher salt. Sifting helps distribute leavening agents and prevents lumps. If you do not have a sifter, whisk the dry ingredients thoroughly to achieve the same result.

4-Fourth Step: Bring the dough together Add the dry ingredients to the wet mixture in two additions, mixing gently until just combined. Overmixing can develop gluten and make cookies tougher. Once the dough is cohesive, fold in 1/2 cup semisweet chocolate chips and the 8 cookies broken into pieces. The broken cookie pieces add texture and double down on the Biscoff flavor.

5-Fifth Step: Chill if needed and portion If the dough is too soft to handle, chill it for 30-60 minutes. The cookie butter and melted butter can make dough slack, especially in warm kitchens. Use a quarter-cup scoop to portion dough for large cookies and place them on a lined baking sheet. If you prefer smaller cookies, use a 3-tablespoon scoop and reduce the baking time (see Tips section).

6-Sixth Step: Refrigerate shaped dough Once scooped, refrigerate the dough balls on the lined baking sheet for at least one hour. This resting period firms the dough and helps the dough hold its shape during baking, producing thicker centers and crisp edges.

7-Seventh Step: Bake Preheat the oven to 350°F. When ready, remove the cookie sheet from the fridge and place dough balls about 2 inches apart to allow for spreading. Bake for 14-15 minutes until the edges are golden but the centers are still slightly underbaked. For smaller 3-tablespoon cookies, bake about 12 minutes. Avoid overbaking; cookies will continue to set as they cool.

8-Final Step: Shape, cool, and finish Optionally shape cookies round immediately after baking by gently pressing with a round cutter or spatula while still warm. Cool the cookies on the baking sheet for 10 minutes before transferring to a wire rack to finish cooling. Warm the remaining 1/4 cup cookie butter and drizzle over the cooled cookies for a glossy topping. Serve slightly warm for melty chocolate and soft centers.
