Key Ingredients
Before you begin, gather these simple pantry staples that come together to create a chewy, spiced masterpiece:
- 1 cup unsalted butter, melted: Rich fat that keeps the blondies soft and adds buttery depth.
- 1 cup packed brown sugar: Provides moisture, caramel notes, and that signature chewiness.
- 1/2 cup granulated sugar: Balances sweetness and helps create a tender crumb.
- 2 large eggs: Binds the ingredients and contributes to the dense, fudgy texture.
- 1 tablespoon vanilla extract: Infuses a warm, aromatic flavor throughout the batter.
- 1 1/2 cups all-purpose flour: The base structure for the bars, ensuring they hold together.
- 1/2 teaspoon baking powder: Gives a gentle lift without compromising the chewy quality.
- 1/4 teaspoon salt: Enhances overall flavor and balances the sweetness.
- 1 cup Biscoff cookie butter: Swirled throughout for that irresistible spiced cookie flavor.
- 1/2 cup Biscoff cookies, crushed (plus more for topping): Adds crunchy texture and extra cookie taste.
How To Make Biscoff Blondies Chewy Cookie Butter Dessert Bars
These step-by-step instructions will guide you through turning ingredients into warm, chewy bars with spiced swirls and cookie crunch. From preheating the oven to the final slice, each move is designed to maximize flavor and texture—no advanced techniques required!
1. Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper, leaving some overhang for easy removal.
2. In a large mixing bowl, whisk together the melted butter, brown sugar, and granulated sugar until well combined and smooth.
3. Add the eggs one at a time, mixing well after each addition, followed by the vanilla extract. Ensure everything is thoroughly blended.
4. In a separate bowl, whisk together the all-purpose flour, baking powder, and salt to create a uniform dry mix.
5. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix or you’ll lose that tender chew.
6. Gently fold in the Biscoff cookie butter until it’s evenly distributed throughout the batter.
7. Carefully stir in the crushed Biscoff cookies until they are incorporated into the mixture, ensuring every bite has a bit of crunch.
8. Pour the batter into the prepared baking pan, spreading it evenly. Sprinkle additional crushed Biscoff cookies on top for extra texture.
9. Bake in the preheated oven for 25–30 minutes, or until the top is lightly golden and a toothpick inserted into the center comes out with a few moist crumbs.
10. Remove from the oven and allow the blondies to cool in the pan for about 15 minutes. Then, use the parchment overhang to lift them out to a wire rack to cool completely.
11. Once cool, cut the blondies into squares or bars and serve!

Frequently Asked Questions
Here are answers to some common questions about these chewy cookie butter bars:
- How long does it take to prepare and bake these Biscoff Blondies?
It takes about 15 minutes to prepare the batter—this includes melting the butter, whisking sugars, adding eggs and vanilla, and combining dry ingredients—then 25–30 minutes to bake. Allow 15 minutes cooling in the pan before transferring to a wire rack, for a total of roughly 1 hour from start to finish.
- Can I use salted butter instead of unsalted, and should I adjust the salt in the recipe?
Yes, you can use salted butter. If you do, reduce or omit the 1/4 teaspoon of added salt in the dry ingredients to prevent the blondies from tasting overly salty. The salted butter will still produce a rich flavor without compromising texture.
- How can I ensure a chewy texture rather than cakey blondies?
For maximum chewiness, avoid overmixing once the flour is added—mix only until the ingredients are just combined. Bake until a toothpick comes out with a few moist crumbs rather than completely clean. Slight underbaking and letting the blondies rest in an airtight container overnight will further enhance chewiness.
- What’s the best way to store leftover blondies, and how long will they stay fresh?
Store cooled blondies in an airtight container at room temperature for up to 3 days. For up to a week, keep them in the refrigerator. You can also freeze individual squares in a sealed freezer bag for up to 3 months; just thaw at room temperature or warm briefly in the microwave before serving.
- Can I substitute any of the ingredients, like using gluten-free flour or different types of sugar?
To make them gluten-free, swap in a 1:1 gluten-free baking flour blend—ensure it contains xanthan gum for structure. You can replace granulated sugar with coconut sugar for a deeper flavor, but note that it may darken the blondies. Brown sugar is essential for moisture and chewiness, so keep that measurement intact.
- How do I create extra cookie butter swirls on top without making a mess?
Dollop small spoonfuls of cookie butter evenly across the top of the batter, then use a butter knife or skewer to gently swirl it into the surface in a figure-eight motion. Be careful not to overmix the swirl into the entire batter—this technique creates attractive ribbons and concentrated pockets of cookie butter.
- Is it possible to add mix-ins like chocolate chips or nuts, and what’s the ideal amount?
Absolutely. Stir in up to 1/2 cup of semi-sweet chocolate chips or chopped nuts (such as pecans or walnuts) along with the crushed Biscoff cookies. Keeping the total mix-ins to about 1 cup ensures the batter holds together well and bakes evenly without sinking or spreading excessively.
