Step 1: Whip the Cream - In a large mixing bowl, pour 1 ½ cups cold heavy cream and add ¼ cup powdered sugar. Use a hand mixer to whip until stiff peaks form.
Step 2: Fold in Biscoff Spread - Gently fold ½ cup smooth Biscoff spread into the whipped cream using a rubber spatula until fully combined and light brown in color.
Step 3: Layer Cookies - In an 8×8 dish, place 16 whole Biscoff cookies in a single layer. Break a few to fill gaps if needed.
Step 4: Add Cream Layer - Spread half of the Biscoff whipped cream mixture over the cookies using a spatula. Smooth out the top.
Step 5: Repeat Layering - Add another layer of 16 Biscoff cookies, then top with the rest of the cream. Smooth it out evenly.
Step 6: Top and Chill - Microwave ¼ cup Biscoff spread for 15–20 seconds until pourable. Drizzle it on top and chill the lasagne for at least 4 hours.
