Chewy Brown Butter Biscoff Blondies with White Chocolate Tips, FAQ & printable recipe

Tips for success

For an even richer flavor profile, add a pinch of sea salt to the batter. The salt helps cut through the sweetness of the white chocolate and enhances the depth of the browned butter.

If you prefer a more pronounced texture, consider using slightly larger chunks of white chocolate. Ensuring the blondies are completely cool before slicing is the most important step for achieving those sharp, professional-looking squares that showcase the beautiful marbling.

Experimenting with the topping can provide a nice contrast to the chewy base. Beyond crushed Biscoff cookies, consider adding a light sprinkle of coarse sugar before baking for an extra crunch.

If you find the blondies are browning too quickly on the edges, you can loosely tent the pan with aluminum foil for the final five minutes of baking. This ensures the center has enough time to cook without compromising the delicate edges of the blondie.

Variations

• Salted Caramel Drizzle: Add a generous drizzle of homemade salted caramel over the finished blondies once they have cooled. The extra saltiness perfectly balances the sweetness of the white chocolate and Biscoff.
• Nutty Crunch: Fold in a half-cup of toasted, chopped pecans or walnuts into the batter. The added crunch provides a wonderful textural contrast to the soft, chewy blondie base.

Storage and make-ahead

Fridge

Store in an airtight container in the refrigerator for up to 5 days.

Freezer

Wrap individual bars tightly in plastic wrap and store in a freezer-safe bag for up to 2 months.

Reheat

Thaw at room temperature or warm briefly in a low-temperature oven for 5 minutes.

Store the blondies in an airtight container at room temperature for up to three days. To maintain their chewy texture, keep the container in a cool, dry place away from direct sunlight. If you live in a particularly humid environment, storing them in the refrigerator can help them last slightly longer, though they should be brought to room temperature before serving to regain their signature fudgy consistency.

These blondies are excellent for making ahead, as the flavors often intensify and meld after sitting for a day. You can bake them, let them cool completely, and store them in an airtight container.

They maintain their quality perfectly for up to 24 hours before serving. If you need to prepare them further in advance, you can freeze the cooled, uncut bars and slice them once they have thawed, which helps keep the edges clean.

Serving ideas

Serve these blondies at room temperature to allow the full depth of the brown butter and the spiced notes of the Biscoff to shine. They make an ideal centerpiece for dessert platters or a sophisticated accompaniment to coffee or tea. Because they are quite rich, cutting them into smaller, bite-sized squares is often preferable, allowing guests to enjoy the intense flavor profile without it being overwhelming.

For a more elaborate dessert experience, serve a square alongside a small scoop of high-quality vanilla bean ice cream. The temperature contrast between the room-temperature blondie and the cold ice cream is delightful.

You can also drizzle a tiny amount of warmed Biscoff spread over the top just before serving to add an extra layer of visual appeal and flavor. This simple addition elevates the dish from a basic bar to a plated restaurant-style dessert.

Chewy Brown Butter Biscoff Blondies with White Chocolate

Prep 15 minCook 22 minRest 30 minTotal 1 h 7 minServes 16

Ingredients

• 1 cup unsalted butter, browned
• 1 1/2 cups dark brown sugar
• 2 large eggs
• 2 cups all-purpose flour
• 1 cup white chocolate chunks
• 1/2 cup Biscoff cookie butter, swirled
• 4 Lotus Biscoff cookies, crushed

Instructions

1. Place the butter in a medium saucepan over medium heat. Cook, stirring constantly, until the milk solids turn golden brown and the butter develops a nutty aroma. Remove from heat immediately to prevent burning and let cool slightly before proceeding with the recipe.
2. In a large mixing bowl, whisk together the browned butter and dark brown sugar until smooth. Add the eggs one at a time, whisking well after each addition. Gently fold in the all-purpose flour and white chocolate chunks until just combined. Finally, swirl in the Biscoff cookie butter to create marbling throughout the batter.
3. Transfer the batter into a parchment-lined 8x8-inch baking pan. Sprinkle the crushed Lotus Biscoff cookies over the top. Bake at 350°F (175°C) for 22 minutes. To ensure the eggs are fully cooked through, bake until an internal temperature of 160°F (71°C) is reached. Allow the blondies to cool completely in the pan before slicing into squares to ensure clean cuts.
