How to Make Biscoff White Chocolate Blondies Recipe

Step 1: Prepare Your Oven and Pan

Start by preheating your oven to 170°C (160°C fan). Lightly grease a baking tin and line it with baking paper, making sure to leave plenty of overhang for easy removal later. This prep ensures your blondies won’t stick and will come out beautifully every time.

Step 2: Crush the Biscoff Biscuits

Set aside 10-12 whole Biscoff biscuits for garnish and roughly break the rest into smaller pieces. These crushed biscuits will add that signature texture and flavor throughout your blondies, giving amazing bursts of spiced crunch in every bite.

Step 3: Cream Butter and Sugars

In the bowl of an electric mixer, beat together the softened butter, caster sugar, and light soft brown sugar until the mixture looks pale and fluffy—this usually takes around 3 minutes. This process is key for creating light, tender blondies with perfect sweetness.

Step 4: Add Vanilla and Eggs

Add the vanilla extract followed by the eggs one at a time, mixing well after each addition. Scrape down the sides of your bowl to ensure everything incorporates smoothly. This step builds the structure and richness that will hold your blondies together.

Step 5: Fold in Flour, Salt, White Chocolate, and Biscuits

Using a spatula or wooden spoon, gently mix in the flour and salt until just combined. Then fold in the chopped white chocolate pieces and the crushed Biscoff biscuits. Be careful not to overmix to keep your blondies delightfully tender and chewy.

Step 6: Spread Batter and Add Biscoff Spread

Transfer the batter into your prepared tin and smooth the top. Reserve about a tablespoon of Biscoff spread for drizzling after baking, then dollop the remaining spread over the batter and gently spread it. This step adds an irresistible, gooey layer of caramelized spice that makes these blondies special.

Step 7: Top and Bake

Top your blondie batter with the reserved whole Biscoff biscuits. Bake for 25 to 30 minutes until golden and just set in the middle. The center should still have a slight wobble and a toothpick inserted will come out with moist crumbs – this guarantees they stay soft and perfectly chewy once cooled.

Step 8: Chill and Finish

Let the blondies cool completely in the tin before transferring them to the fridge for at least a couple of hours or ideally overnight. Only cut the blondies when chilled—that way they hold their shape beautifully without being too gooey. Just before serving, warm the reserved Biscoff spread and drizzle it over the top for an extra glossy, flavorful flourish.

Garnishes

To elevate your blondies, sprinkle with a dusting of crushed Biscoff biscuits or white chocolate shavings. Adding a few whole biscuits on top not only looks stunning but amplifies the delightful crunchy texture contrast.

Side Dishes

Pair these blondies with a scoop of vanilla ice cream or a drizzle of warm caramel sauce for an extra indulgent dessert experience. A cup of rich coffee or creamy latte also makes a perfect companion, balancing the sweetness with bold coffee notes.

Creative Ways to Present

Make Ahead and Storage

Storing Leftovers

Keep leftover Biscoff White Chocolate Blondies in an airtight container at room temperature for up to three days or in the fridge for up to a week. This will maintain their chewy texture and rich flavor, ensuring every bite still tastes fresh and delicious.

Freezing

You can freeze these blondies by wrapping individual portions tightly in cling film and placing them in a freezer-safe container. They’ll keep beautifully for up to two months. When you’re ready to enjoy, just thaw at room temperature or microwave briefly to revive that fresh-baked taste.

Reheating

To bring your blondies back to life, warm them gently in the microwave for about 15 seconds or heat in a warm oven for 5 minutes. This makes the white chocolate melty and the Biscoff spread ooze slightly, making every bite utterly irresistible again.

FAQs

Can I use crunchy Biscoff spread instead of smooth?

Absolutely! Using crunchy Biscoff spread will add an extra lovely texture to your blondies, giving little pockets of crunch that complement the biscuits and white chocolate perfectly.

What is the best pan size for this recipe?

A 20×20 cm (8×8 inch) tin works best to achieve that perfect thickness and cook time. Using a larger pan may result in thinner blondies that bake faster, so adjust baking time accordingly if needed.

Can I substitute white chocolate for milk or dark chocolate?

Yes, but keep in mind it will change the flavor profile. White chocolate adds creamy sweetness that balances beautifully with the cinnamon spice of Biscoff, while milk or dark chocolate will bring a richer, deeper chocolate taste.

How long should I chill the blondies?

Chilling for at least a couple of hours is essential, but overnight is ideal to let the bars firm up and develop a better texture. Cutting them too soon will make them fall apart because they are still warm and gooey.

Can I make these vegan?

To make a vegan version, substitute butter with a vegan spread, use flax eggs instead of regular eggs, and check that your white chocolate is dairy-free. The Biscoff biscuits and spread are typically vegan, making this an easy swap!
