Essential Ingredients for Chewy Biscoff Blondies Recipe
Wet Ingredients:
- 1 cup (240g) Biscoff cookie butter (smooth or crunchy—your call!)
- ½ cup (115g) unsalted butter, melted and slightly cooled
- 1 cup (200g) light brown sugar, packed
- 2 large eggs, room temperature
- 1 tablespoon vanilla extract
Dry Ingredients:
- 1½ cups (190g) all-purpose flour
- ½ teaspoon baking powder
- ½ teaspoon salt
Mix-Ins:
- 1 cup (170g) white chocolate chips
- ½ cup (60g) crushed Biscoff cookies (optional, but highly recommended for texture!)
Important Kitchen Essentials
- 9×9-inch square baking pan (or 8×8 for thicker blondies)
- Parchment paper (makes cleanup a breeze!)
- Large mixing bowl
- Whisk or sturdy spoon
- Rubber spatula
- Toothpick (for the doneness test)
Instructions for Chewy Biscoff Blondies Recipe
1. Preheat your oven to 350°F (175°C) and line your pan with parchment paper, leaving overhang on two sides for easy lifting.
2. In a large bowl, whisk together the melted butter, Biscoff spread, and brown sugar until smooth and glossy (about 1 minute).
3. Add the eggs and vanilla, whisking until thoroughly combined and the mixture looks thick and creamy.
4. Sprinkle the flour, baking powder, and salt over the wet ingredients, then gently fold with a spatula until just combined—don’t overmix or you’ll get tough blondies!
5. Fold in ¾ cup of the white chocolate chips and the crushed Biscoff cookies (if using), reserving the rest of the chips for topping.
6. Pour the batter into your prepared pan, spreading evenly with a spatula, then scatter the remaining ¼ cup white chocolate chips on top.
7. Bake for 25-30 minutes, until the edges are golden and a toothpick inserted in the center comes out with a few moist crumbs (not wet batter, but not totally clean—that’s the chewy sweet spot!).
8. Let cool in the pan for at least 30 minutes before lifting out and slicing—this step is crucial for clean cuts and the right texture!

Substitutions for Common Ingredients
No Biscoff spread? Use speculoos cookie butter, Trader Joe’s cookie butter, or even Nutella (though flavor will change).
No white chocolate chips? Try milk chocolate chips, butterscotch chips, or chopped white chocolate bars.
No brown sugar? Use 1 cup of granulated sugar and one tablespoon of molasses, or just granulated sugar (the texture will be slightly less chewy).
Gluten-free? Swap all-purpose flour for 1:1 gluten-free baking flour (Bob’s Red Mill works great!).
Dairy-free? Use vegan butter and dairy-free white chocolate chips (Enjoy Life brand is excellent).
No eggs? Try two flax eggs (2 tablespoons ground flaxseed + 6 tablespoons water, let sit for 5 minutes)—the texture will be slightly denser.
Additional Tips for Chewy Biscoff Blondies
- Don’t overbake! The toothpick should have moist crumbs, not come out clean—blondies continue cooking as they cool.
- Room-temperature eggs matter – They mix more smoothly and create a better texture (quick hack: place eggs in warm water for 5 minutes).
- For clean cuts, chill the blondies in the fridge for 30 minutes, then use a sharp knife that has been wiped clean between each cut.
- Crush cookies in the bag – Seal Biscoff cookies in a zip-top bag and smash with a rolling pin—no dishes to wash!
- Use an 8×8 pan for thicker blondies (bake 32-35 minutes) or a 9×13 pan for thinner, crispier bars (bake 20-22 minutes).
- Quality matters – Since Biscoff spread is the star, use a fresh jar for the best flavor.
Precautions for Chewy Biscoff Blondies
Allergy Alert: Contains gluten, dairy, eggs, and soy (in most cookie butters and white chocolate). Check labels if you have allergies!
Oven temps vary – Start checking at 25 minutes; some ovens run hot and can dry out blondies quickly.
Let them cool completely before cutting, or they’ll fall apart—patience is hard, we know!
Cookie butter can separate – If your jar has oil on top, stir it back in before measuring.
Store properly – Keep in an airtight container at room temp for up to 5 days, or freeze for up to 3 months.
Choking hazard – White chocolate chips can be a risk for very young children; consider melting them in or omitting them.

People Frequently Ask
Can I use crunchy Biscoff spread instead of the smooth variety?
Absolutely! Crunchy spread adds extra texture and those little cookie bits throughout—it’s delicious either way, so go with your preference!
Why are my blondies dry instead of chewy?
You likely overbaked them! Blondies should come out when a toothpick has moist crumbs, not when it’s spotless. They firm up as they cool, so pull them out a little early.
Can I make these without white chocolate chips?
Yes! You can omit them entirely, double the crushed Biscoff cookies, or substitute with any chips you like—milk chocolate, dark chocolate, or even butterscotch works great.
How do I know when blondies are done baking?
The edges should be golden and set, while the center should appear slightly underdone (it should jiggle just a bit). A toothpick inserted 2 inches from the edge should have moist crumbs—that’s your perfect chewy texture!
Can I double this recipe?
Definitely! Double everything and use a 9×13-inch pan. Bake for 30-35 minutes, checking for doneness with the toothpick test. Perfect for feeding a crowd!
