Introduction

Biscoff blondies are a rich and chewy treat featuring the distinctive caramelized flavor of Biscoff spread and cookies. These bars combine smooth white chocolate and crunchy cookie bits for an irresistible dessert that’s easy to make at home.

Ingredients

½ cup (115g) unsalted butter, melted
¾ cup (150g) brown sugar
¼ cup (50g) granulated sugar
1 large egg, room temperature
1 tsp vanilla extract
½ cup (120g) Biscoff spread (smooth or crunchy)
1 cup (125g) all-purpose flour
½ tsp baking powder
¼ tsp salt
½ cup (90g) white chocolate chips or chunks
6–8 Biscoff cookies, crushed or halved
Optional: sea salt flakes, chopped nuts, extra Biscoff for drizzling

Instructions

Step 1: Preheat your oven to 350°F (175°C) and line an 8×8-inch pan with parchment paper for easy removal.
Step 2: In a mixing bowl, combine the melted butter, brown sugar, and granulated sugar. Stir until the mixture is smooth and even.
Step 3: Add the egg and vanilla extract, mixing thoroughly until fully incorporated.
Step 4: Stir in the Biscoff spread until the batter is creamy and well blended.
Step 5: Add the flour, baking powder, and salt. Mix gently just until combined to avoid overmixing.
Step 6: Fold in the white chocolate chips and half of the crushed Biscoff cookies for texture.
Step 7: Pour the batter into the prepared pan and smooth the top evenly.
Step 8: Dollop extra Biscoff spread on top and swirl it with a knife. Sprinkle the remaining cookie pieces over the batter.
Step 9: Bake for 25–30 minutes until the edges turn golden and the center is just set but still soft.
Step 10: Allow the blondies to cool completely in the pan before slicing into squares. For extra indulgence, drizzle with melted Biscoff or white chocolate as desired.

Tips & Variations

For a richer flavor, use crunchy Biscoff spread and add chopped nuts like pecans or walnuts for extra texture.
Swap white chocolate chips for milk or dark chocolate if you prefer a different chocolate profile.
Sprinkle a pinch of sea salt flakes on top before baking to enhance the caramel notes.
To make these vegan, substitute butter with coconut oil and use a flax egg instead of a regular egg.

Storage

Store the blondies in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week. Reheat gently in the microwave if desired to soften the chocolate and Biscoff spread.

1 large egg, room temperature
1 tsp vanilla extract
½ cup (120g) Biscoff spread (smooth or crunchy)

½ tsp baking powder
¼ tsp salt

Add-ins and Toppings

½ cup (90g) white chocolate chips or chunks
6–8 Biscoff cookies, crushed or halved
Optional: sea salt flakes, chopped nuts, extra Biscoff for drizzling

Instructions

Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper to prevent sticking and make removal easier.
Combine Sugars and Butter: In a mixing bowl, stir together the melted butter, brown sugar, and granulated sugar until the mixture is smooth and well combined.
Add Egg and Vanilla: Add the room temperature egg and vanilla extract to the sugar mixture. Mix thoroughly until fully incorporated and the batter is smooth.
Incorporate Biscoff Spread: Stir in the Biscoff spread until the batter is creamy and well blended, ensuring even distribution of the signature flavor.
Add Dry Ingredients: Gently mix in the flour, baking powder, and salt until just combined. Be careful not to overmix to maintain a tender blondie texture.
Fold in Chocolate and Cookies: Fold in the white chocolate chips and half of the crushed Biscoff cookies to add texture and bursts of flavor.
Transfer Batter and Smooth: Pour the batter into the prepared baking pan and smooth the top evenly with a spatula.
Top with Biscoff and Cookies: Dollop extra Biscoff spread on the top and swirl it through with a knife. Sprinkle the remaining cookie pieces evenly over the surface.
Bake: Bake in the preheated oven for 25–30 minutes, or until the edges turn golden brown and the center is just set but still soft.
Cool and Slice: Allow the blondies to cool completely in the pan before slicing into squares. For extra indulgence, drizzle melted Biscoff spread or white chocolate over the top before serving, if desired.

Notes

Ensure the egg is at room temperature to help the batter emulsify properly and to achieve the best texture.
Do not overmix the batter after adding the flour to keep the blondies tender and moist.
If you prefer a crunchier texture, use crunchy Biscoff spread and include chopped nuts as an optional topping.
Cool completely before slicing to avoid crumbling and to get clean, neat blondie squares.
For a richer flavor, drizzle extra melted Biscoff or white chocolate before serving.
