What You Need
- 1 cup unsalted butter
- 1 cup Biscoff cookie butter
- 1 cup brown sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon salt
- 1/2 cup white chocolate chips
- 1/2 cup crushed Biscoff cookies
Step-by-Step
- Preheat your oven to 350°F (175°C) and grease a 9×9-inch square baking pan or line it with parchment paper for easy removal.
- In a medium-sized saucepan, melt the unsalted butter and Biscoff cookie butter together over low heat, stirring occasionally until the mixture is smooth and fully combined.
- Remove the saucepan from the heat and allow the mixture to cool slightly for about 5 minutes.
- Add the brown sugar to the butter mixture and whisk until fully combined and smooth.
- Crack the two large eggs into the bowl with the butter and sugar mixture and whisk until the eggs are completely incorporated.
- Stir in the vanilla extract, ensuring it is evenly distributed throughout the mixture.
- In a separate large bowl, sift together the all-purpose flour, baking powder, and salt to ensure the dry ingredients are well mixed.
- Slowly add the sifted dry ingredients into the wet ingredients, stirring gently with a spatula or wooden spoon to combine. Be careful not to overmix the batter, as this can result in dense blondies.
- Once the batter is just combined and smooth, fold in the white chocolate chips and crushed Biscoff cookies. Stir until evenly distributed throughout the batter.
- Pour the blondie batter into the prepared baking pan, spreading it out evenly with a spatula to make sure it reaches all the corners.
- Place the pan in the preheated oven and bake for 25 to 30 minutes. Check the blondies by inserting a toothpick into the center; if it comes out clean or with just a few crumbs, the blondies are done.
- Allow the blondies to cool in the pan on a wire rack for about 10 minutes before removing them from the pan and letting them cool completely on the wire rack.
- Once cooled, cut the blondies into squares and serve. Enjoy!

How to Serve Biscoff Blondies
These blondies are delicious on their own but can be even better with a scoop of vanilla ice cream. You might also enjoy them with a drizzle of caramel sauce or chocolate syrup. They’re perfect for a family movie night or a gathering with friends. Serve alongside a cup of coffee or hot chocolate for a cozy treat.
How to Store Biscoff Blondies
To keep your blondies fresh, store them in an airtight container at room temperature for up to 5 days. If you want to keep them longer, you can freeze them. Just wrap each blondie individually in plastic wrap and place them in a freezer bag. They’ll last for about three months. To enjoy, simply thaw at room temperature or heat in the microwave for a few seconds.
Recipe Tips
- Make sure not to overmix the batter or the blondies may become dense.
- For a chewier texture, try using brown sugar in place of half the granulated sugar.
- Feel free to swap half of the white chocolate chips with dark chocolate if you prefer that flavor.
- If you’d like to boost the spice, add a pinch of cinnamon to your dry ingredients.
- Don’t forget to allow the butter mixture to cool a bit before adding the eggs to prevent them from cooking.
