With their golden crust and soft, gooey center, Biscoff Blondies are a modern dessert favorite, and their popularity continues to grow as people search for new ways to enjoy the distinct, spiced taste of Biscoff in classic baked goods.
Whether baked for a special occasion or whipped up as a comforting treat, these blondies deliver sweet satisfaction in every bite.
Ingredients
- 1 cup (225g) unsalted butter, melted and cooled slightly
- 1 and 1/4 cups (250g) light brown sugar, packed

- 1/2 cup (90g) white chocolate chips (optional)

- Spread the batter evenly into the prepared baking pan. Drop spoonfuls of additional Biscoff spread on top, if desired, and swirl with a knife.
- Bake for 25-30 minutes, or until the edges are golden brown but the center is still slightly soft to ensure a chewy texture.

- Cut into squares and enjoy. Store any leftovers in an airtight container at room temperature for up to 4 days.

Nutritional Information
Biscoff Blondies, while undeniably delicious, are a decadent treat best enjoyed in moderation. A typical serving (one square, when cut into 20 pieces) contains approximately 250-300 calories, with about 14 grams of fat, 35 grams of carbohydrates, and 3 grams of protein.
The rich flavor comes from the combination of melted butter, Biscoff spread, and brown sugar, offering a substantial amount of both fats and sugars. Due to the presence of wheat flour and cookie crumbs, these blondies are not gluten-free and contain a moderate amount of sodium.
The addition of eggs provides a modest protein boost, and white chocolate chips contribute extra carbohydrates and fats if included. While Biscoff Blondies do not provide significant vitamins or minerals, they do offer small amounts of calcium (from eggs), iron (from flour), and a trace of potassium.
Remember that balance is key: enjoying these blondies as an occasional treat as part of a varied diet is a great way to savor their unique flavor without overindulgence.
Wine and Beverage Pairings
Biscoff Blondies pair beautifully with a wide range of beverages, enhancing both the dessert and drink experience. For a cozy afternoon, many enjoy serving their blondies with a steaming mug of coffee or espresso—the caramel notes in both the blondies and coffee are a match made in heaven.
For tea lovers, a spiced chai latte or robust black tea like Assam or English Breakfast balances the sweet richness of the blondies.
If you prefer to serve these at a dinner party, a gently chilled dessert wine such as a Muscat or a late harvest Riesling can highlight the cookie butter’s warm flavors. Non-alcoholic options include a glass of cold milk, oat milk, or even a spiced hot chocolate for chilly evenings.
When planning pairings, choose drinks that echo or complement the Biscoff Blondies’ caramel and cinnamon undertones.
Cooking Tips and Variations
To achieve the perfect Biscoff Blondies, consider these helpful tips and fun variations. Always use room temperature eggs for smoother blending and an even texture. For easier removal from the pan, don’t skip lining the baking dish with parchment paper and leaving an overhang.
If you like your blondies extra gooey, slightly underbake them and let them cool in the pan, as they will continue to firm up as they cool.
For a visual swirl, warm an extra two tablespoons of Biscoff spread and drizzle it on top of the batter before baking, swirling with a toothpick or knife for an attractive marbled effect.
If you’re looking to switch up flavors, consider adding chopped nuts like pecans or walnuts for a crunchy contrast, or replace white chocolate chips with milk or dark chocolate. For a vegan option, substitute eggs with flax eggs and use dairy-free butter.
You can also adapt for gluten-free diets by using a 1:1 gluten-free flour blend, just check that your Biscoff cookies are gluten-free as well. Finally, for extra indulgence, serve the blondies warm with a scoop of vanilla ice cream or a drizzle of melted chocolate.

Serving Suggestions
Biscoff Blondies delight guests whether served at casual gatherings, elegant parties, or as a weekday treat. For a classic presentation, cut the blondies into equally sized squares or rectangles, arranging them on a decorative platter.
If preparing for a celebration, dust the tops with powdered sugar, add a few extra crumbled Biscoff cookies, or drizzle with melted Biscoff spread for an elevated look.
Serving these blondies slightly warm enhances their gooey texture and brings out the caramelized flavors, so consider gently reheating slices in the microwave for 10-15 seconds. For a decadent dessert plate, pair warm Biscoff Blondies with scoops of gelato, ice cream, or a dollop of freshly whipped cream.
At bake sales or coffee mornings, individually wrap blondie squares in parchment or cellophane for easy sharing. If you want to impress, create a blondie sundae station with various toppings—including chocolate chips, nuts, sprinkles, and fresh berries.
However you choose to enjoy or present them, Biscoff Blondies will always be a crowd-pleasing centerpiece.
Health Benefits
While Biscoff Blondies are primarily a sweet treat enjoyed for their flavor and texture, there are a few subtle health benefits to consider when enjoyed occasionally as part of a balanced diet.
Biscoff spread contains a moderate amount of unsaturated fats, which are healthier for your heart than their saturated counterparts. The eggs provide a source of protein and essential nutrients, such as vitamin D, choline, and selenium.
Making your own blondies at home allows you to control the ingredients, potentially reducing the amount of sugar or using alternative sweeteners as desired.
For those interested in boosting the health factor, substituting part of the all-purpose flour with whole wheat flour can add dietary fiber, aiding digestion and providing longer-lasting energy. Adding chopped nuts for texture introduces healthy fats and micronutrients such as magnesium and vitamin E.
Nevertheless, Biscoff Blondies are best enjoyed in moderation, as they are calorie-dense and high in sugar. Enjoying them as an occasional treat aligns with maintaining a healthy, well-rounded diet.
