How to Make Biscoff Blondies
Ingredients You’ll Need
1 cup unsalted butter, melted
1 cup brown sugar, packed
1/2 cup granulated sugar
2 large eggs
1 tablespoon vanilla extract
2 cups all-purpose flour
1 teaspoon baking powder
1/2 teaspoon baking soda
1/4 teaspoon salt
1 cup Biscoff cookie butter
1/2 cup Biscoff cookies, crushed (plus extra for topping)
Sea salt, for sprinkling
Step-by-Step Directions
Preheat your oven to 350°F (175°C) and grease or line a 9×13 inch baking pan with parchment paper, allowing some overhang for easy removal.
In a large mixing bowl, combine the melted butter, brown sugar, and granulated sugar. Whisk until the mixture is smooth and well combined.
Add the eggs one at a time, whisking until fully incorporated after each addition. Stir in the vanilla extract.
In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
Gradually mix the dry ingredients into the wet ingredients using a spatula or wooden spoon until just combined. Be careful not to overmix.
Gently fold in the Biscoff cookie butter until the batter is smooth. You can leave some swirls of cookie butter for a marbled effect.
Fold the crushed Biscoff cookies into the batter, reserving a handful for topping later.
Pour the batter into the prepared baking pan, spreading it evenly. Sprinkle the reserved crushed Biscoff cookies on top.
Bake in the preheated oven for 25-30 minutes or until a toothpick inserted in the center comes out mostly clean with a few moist crumbs. Avoid overbaking to keep them chewy.
Once baked, remove from the oven and sprinkle a pinch of sea salt over the top while it is still warm.
Allow the blondies to cool in the pan for about 15 minutes, then lift them out using the parchment paper overhang and transfer to a wire rack to cool completely before cutting into squares.
How to Serve Biscoff Blondies
These Biscoff Blondies are great on their own, but you can also serve them warm with a scoop of vanilla ice cream on top for an extra treat. You can dust them with powdered sugar for a sweet touch or drizzle some extra Biscoff cookie butter on top. They can be enjoyed as a dessert or cut into smaller squares to serve at gatherings.
How to Store Biscoff Blondies
To store any leftover Biscoff Blondies, place them in an airtight container at room temperature. They will stay fresh for about 3 to 5 days. If you want to keep them for longer, you can also refrigerate them. Just make sure to let them come to room temperature before serving again for the best texture.
Tips for the Best Biscoff Blondies
To get the best results with your Biscoff Blondies, be careful not to overmix your batter. Mixing just until combined will keep them chewy and soft. Always use fresh ingredients for the best flavor. You can also try adding nuts or chocolate chips for a different twist on this recipe.

Recipe Variations
