how to make Biscoff Blondies
Ingredients :
- For the butter mix:
- 1 cup unsalted butter, melted (or briefly warmed)
- 1 cup Biscoff cookie butter (room temperature)
- For the sweet mix:
- 1 cup packed brown sugar
- 2 large eggs (room temperature)
- 1 teaspoon vanilla extract
- For the dry mix:
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon salt
- For fold-ins and topping:
- 1/2 cup white chocolate chips
- 1/2 cup crushed Biscoff cookies (plus extra for the top if you like)
How to Make Biscoff Blondies
- Preheat and prepare: Preheat the oven to 350°F (175°C). Grease a 9×9-inch square pan or line it with parchment paper so the blondies lift out easily.
- Melt the butters: In a small saucepan over low heat, melt the unsalted butter and the Biscoff cookie butter together. Stir until smooth, then take off the heat. Let sit about 5 minutes to cool slightly. (Cooling keeps the eggs from cooking.)
- Add sugar: Whisk the brown sugar into the warm butter mixture until smooth. This helps dissolve the sugar and makes a shiny batter.
- Add eggs and vanilla: Crack in the eggs one at a time and whisk until each is fully mixed in. Stir in the vanilla. The batter should look glossy.
- Mix dry ingredients: In a large bowl, sift or whisk together the flour, baking powder, and salt. Mixing dry ingredients first helps even distribution and prevents pockets of baking powder.
- Combine wet and dry: Stir the dry mix into the wet mix slowly with a spatula. Mix just until you no longer see flour streaks. Do not overmix — overworking the batter makes dense blondies.
- Fold in chips and cookies: Gently fold the white chocolate chips and crushed Biscoff cookies into the batter so they spread evenly.
- Bake: Spread the batter evenly in the prepared pan, pressing into the corners. Bake 25–30 minutes. A toothpick in the center should come out clean or with a few moist crumbs for chewy blondies.
- Cool and cut: Let the blondies cool in the pan on a wire rack for 10 minutes, then lift out and cool completely before slicing. Cooling finishes the set and prevents them from falling apart.
- Serve: Cut into squares and enjoy.
how to serve Biscoff Blondies
Serve warm or at room temperature. Top warm blondies with a small scoop of vanilla ice cream for a dessert. For parties, plate squares with extra crushed Biscoff sprinkled on top. They pair well with coffee or milk.
how to store Biscoff Blondies
- Room temp: Store in an airtight container for up to 3 days.
- Fridge: Keep covered for up to 1 week. Bring to room temp before serving for best texture.
- Freezer: Wrap tightly and freeze up to 2 months. Thaw in the fridge or on the counter, then warm briefly if desired.
tips to make Biscoff Blondies
- Use room-temperature eggs so they blend smoothly.
- Don’t overmix after you add flour; stop when just combined.
- If Biscoff is very thick, warm it slightly so it blends easily with butter.
- Press extra crushed cookies on top before baking for a crunchy finish.
- Test doneness at 25 minutes; ovens vary.
variation (if any)
- Chocolate Biscoff: Swap white chocolate chips for semi-sweet or milk chocolate chips.
- Nuts: Add 1/2 cup chopped pecans or walnuts for crunch.
- Gluten-free: Use a 1:1 gluten-free flour blend instead of all-purpose flour.
FAQs
Can I use crunchy Biscoff instead of cookie butter?
Yes. Crunchy Biscoff pieces can add texture, but they won’t melt into the batter the same way. If using crunchy cookie spread, warm it slightly first.
Can I make these gluten-free?
Yes. Replace the all-purpose flour with a 1:1 gluten-free flour blend that contains xanthan gum. Bake the same time but check with a toothpick.
How do I keep them chewy, not dry?
Do not overbake. Remove when a toothpick shows a few moist crumbs. Let cool in the pan for 10 minutes before moving to a rack.
Can I use salted butter?
You can, but reduce additional salt to 1/4 teaspoon or skip it to keep balance.
Are these freezer-friendly?
Yes. Wrap squares well and freeze up to 2 months. Thaw overnight in the fridge or thaw on the counter for a few hours.
