Ingredients
Cookie butter meets blondies in these soft and chewy Biscoff Blondies, sprinkled with white chocolate throughout. They are sweet, spiced, and indulgent.
For the Blondies Base
- ¾ cup (1½ sticks or 170g) unsalted butter
- ½ cup (140g cookie) butter spread (I used Biscoff brand)
- 1 cup (200g) brown sugar
- ½ cup (100g) granulated sugar
- 2 large eggs (at room temperature)
- 1 teaspoon vanilla extract
For the Dry Ingredients
- 2 cups (240g) all-purpose flour
- 1¼ teaspoons baking powder
- ½ teaspoon salt
- ¼ teaspoon cinnamon
For the Mix-ins
- ⅔ cup (130g) white chocolate chips
- 6-8 Biscoff cookies
- 2 Tablespoons (35g) cookie butter spread
How to Make Biscoff Blondies
Step 1: Preheat the Oven
Preheat oven to 350°F. Lightly grease a 9” x 9” square pan with cooking spray. Line the pan with parchment paper to create a sling that overhangs on all four sides.
Step 2: Prepare the Batter
Melt the butter and allow it to cool slightly. In a large mixing bowl, add:
1. Melted butter
2. Cookie butter spread
3. Brown sugar
4. Granulated sugar
Whisk well until combined.
Step 3: Add Eggs and Vanilla
Add in the eggs and vanilla extract, mixing together for about 30 seconds until fully incorporated.
Step 4: Combine Dry Ingredients
Add the flour, baking powder, salt, and cinnamon. Mix with a spatula until only a few streaks of flour remain. Gently fold in the white chocolate chips.
Step 5: Bake
Pour the batter into the prepared pan. Spread it evenly using an offset spatula. Top with broken and crushed Biscoff cookie pieces. Bake for 30-35 minutes until the center is just set and edges are golden brown. A toothpick inserted should come out with a few moist crumbs.
Step 6: Cool & Serve
Allow the blondies to cool completely. Melt the additional cookie butter spread and drizzle it over the top of the blondies. Cut into 16 equal squares, serve, and enjoy!
How to Serve Biscoff Blondies
Biscoff Blondies are a delightful treat that can be enjoyed in various ways. Here are some serving suggestions to elevate your dessert experience.
With a Scoop of Ice Cream

- Try adding a drizzle of caramel sauce on top for extra sweetness.
Topped with Whipped Cream
- A dollop of whipped cream adds a light and airy texture that complements the rich blondies.
- Consider sprinkling some crushed Biscoff cookies on the whipped cream for added flavor and crunch.
Dipped in Milk
- Serve your blondies with a side of cold milk for dunking, enhancing their chewy texture.
- Use flavored milk, like chocolate or almond, for a twist on this traditional pairing.
Served with Fresh Fruit

How to Perfect Biscoff Blondies
To achieve the ultimate Biscoff Blondies, consider these helpful tips.
- Use room temperature ingredients – This helps create a smoother batter and ensures even mixing.
- Do not overmix – Stop mixing as soon as you see no flour streaks. Overmixing can lead to tough blondies.
- Check for doneness – Insert a toothpick; it should come out with some moist crumbs but not wet batter.
- Cool completely before cutting – Allowing them to cool helps maintain their structure when you slice them.
- Store properly – Keep leftovers in an airtight container at room temperature for up to four days to retain freshness.
- Experiment with mix-ins – Feel free to add nuts or additional chocolate chips for added texture and flavor variations.

Common Mistakes to Avoid
Baking Biscoff Blondies can be a delightful experience, but there are some common mistakes to watch out for. Here’s how to ensure your blondies turn out perfectly.
-
Skipping the Cooling Step: Allow the melted butter to cool slightly before mixing. This prevents the eggs from cooking prematurely when added.
-
Overmixing the Batter: Mixing too much after adding flour can lead to dense blondies. Stop mixing as soon as you see a few streaks of flour.
-
Incorrect Baking Time: Check your blondies a few minutes before the recommended time. Overbaking can dry them out; they should be golden with a slight jiggle in the center.
-
Not Using Parchment Paper: Always line your baking pan with parchment paper. This makes it easier to remove the blondies without sticking.
-
Ignoring Ingredient Temperature: Make sure your eggs are at room temperature. Cold eggs can affect the batter’s consistency and rise.
