Brown Sugar – Sweetness with a hint of molasses richness. Use dark brown for more flavor, or light for a milder taste.

Step‑by‑Step Instructions for Biscoff Cookie Butter Blondies

Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (177°C). While the oven heats, line an 8×8-inch baking pan with parchment paper, allowing some overhang for easy removal later. This preparation ensures your Biscoff Cookie Butter Blondies will bake evenly while also making cleanup a breeze.

Step 2: Mix the Wet Ingredients
In a large mixing bowl, combine the brown sugar, neutral oil, eggs, and vanilla paste. Whisk these ingredients together until the mixture is smooth, taking care to break up any clumps of sugar. This base creates a rich sweetness that perfectly complements the spices in the blondies.

Step 3: Combine the Dry Ingredients
Next, gently incorporate the all-purpose flour, table salt, and your choice of ground spices into the wet mixture. Stir until just combined, being careful not to overmix. Adding the crushed Biscoff cookies at this stage enhances the batter with delightful bits of crunchy flavor throughout.

Step 4: Transfer and Spread the Batter
Pour the blondie batter into your prepared baking pan. Use a spatula to spread it evenly across the bottom, ensuring a consistent layer. The batter should look thick and slightly glossy as you smooth it out, ready to become the base of your delicious Biscoff Cookie Butter Blondies.

Step 5: Add the Topping
Drizzle warm Biscoff spread evenly over the surface of the batter, then sprinkle the remaining crushed Biscoff cookies on top. This layer will melt into the blondies as they bake, infusing them with that irresistible cookie flavor and a creamy texture that adds a unique twist.

Step 6: Bake to Perfection
Bake your Biscoff Cookie Butter Blondies for 35-40 minutes. Keep an eye on them, and use a toothpick to check for doneness—a few moist crumbs should cling to the toothpick when they’re ready. They should have a golden-brown hue and a slightly puffed appearance when you remove them from the oven.

Step 7: Cool and Cut
Once baked, let the blondies cool in the pan for about one hour. This cooling time is essential for achieving the perfect chewy texture. After they’ve cooled, use the parchment overhang to lift them out and slice into squares for serving.

Expert Tips for Biscoff Cookie Butter Blondies
