Step‑by‑Step Instructions for Biscoff Blondies
Step 1: Preheat and Prepare the Pan
Begin by preheating your oven to 350°F (175°C). While the oven heats, prepare your 9×9-inch baking pan by greasing it lightly or lining it with parchment paper for easy removal later. This step ensures you have a non-stick surface for your Biscoff Blondies.
Step 2: Melt Butter and Cookie Butter
In a medium saucepan, melt ½ cup of unsalted butter along with ½ cup of Biscoff cookie butter over low heat. Stir the mixture continuously until it becomes smooth and glossy, showing that the two have fully combined. This should take about 3-5 minutes, releasing a warm, inviting aroma in your kitchen.
Step 3: Mix in Brown Sugar
Remove the saucepan from the heat and let the mixture cool slightly for about 5 minutes. Once it has cooled, whisk in 1 cup of brown sugar until the mixture is smooth and shiny. This adds a lovely caramel flavor to your Biscoff Blondies and will create a luxurious texture.
Step 4: Incorporate Eggs and Vanilla
Next, add two large eggs to the mixture one at a time, whisking well after each addition until fully combined. Then, pour in 1 teaspoon of pure vanilla extract. These ingredients will provide richness and enhance the flavor, contributing to the overall delightful taste of your blondies.
Step 5: Combine Dry Ingredients
In a separate bowl, sift together 1 ½ cups of all-purpose flour, 1 teaspoon of baking powder, and a pinch of salt. This step ensures there are no clumps in your dry ingredients and allows for even distribution when mixed with the wet ingredients, resulting in light and fluffy Biscoff Blondies.
Step 6: Bring Wet and Dry Ingredients Together
Gradually add the dry ingredient mixture into the wet ingredients, stirring gently with a spatula until just combined. Be careful not to overmix; a few flour streaks are perfectly fine. This careful approach maintains the chewy texture that makes these Biscoff Blondies so irresistible.
Step 7: Fold in Chocolate and Cookies
Gently fold in 1 cup of white chocolate chips and ½ cup of crushed Biscoff cookies into the batter. This adds delightful pops of sweetness and texture. Ensure the mix is uniform, so every bite of the blondies is filled with chocolate and delicious cookie bits.
Step 8: Bake the Blondies
Pour the batter into the prepared baking pan and spread it evenly. Bake in the preheated oven for 25-30 minutes. To check for doneness, insert a toothpick into the center; it should come out clean or with a few moist crumbs. This indicates that your Biscoff Blondies are perfectly baked.
Step 9: Cool and Slice
Once baked, remove the pan from the oven and let the blondies cool in the pan for about 10 minutes. Then, carefully transfer them to a wire rack using the edges of the parchment paper. Allow them to cool completely before cutting into delightful squares to enjoy.

Expert Tips for Biscoff Blondies
Avoid Overmixing: Keep it light; overmixing can lead to dense blondies rather than the soft, chewy texture we all love.
Perfect Doneness Check: Insert a toothpick into the center; it should come out with a few moist crumbs for that ideal, soft consistency in your Biscoff blondies.
Parchment for Easy Removal: Use parchment paper to line the pan; it makes transferring and slicing your blondies a breeze without sticking.
Storing the Bliss: Store in an airtight container for up to 3-4 days, so you can enjoy this sweet treat without sacrificing freshness!
Dress Them Up: For an extra gourmet touch, serve warm with a scoop of vanilla ice cream or a drizzle of caramel sauce for that decadent finish.

Biscoff Blondies Recipe FAQs
How do I choose ripe ingredients for my Biscoff Blondies?
When selecting ingredients like unsalted butter and eggs, ensure the butter is fresh and not overly soft or melted as it can affect the texture. Eggs should be at room temperature, which helps them blend more smoothly into your batter.
How should I store Biscoff Blondies?
Store your Biscoff blondies in an airtight container at room temperature for up to 3-4 days to maintain their chewy texture. If it’s particularly warm, refrigerating them can extend freshness to about a week. Just make sure to bring them back to room temperature before serving for the best flavor!
Can I freeze my Biscoff Blondies?
Absolutely! To freeze, wrap each blondie square individually in plastic wrap, then place them in a freezer-safe bag. This will help prevent freezer burn and keep them fresh for up to 2-3 months. Whenever you’re ready to enjoy, simply thaw at room temperature or reheat in the microwave for about 10-15 seconds.
What should I do if my blondies turned out too dense?
If you find your Biscoff blondies have a dense texture, it may be due to overmixing the batter. To prevent this next time, mix the wet and dry ingredients just until they are combined—it’s okay if there are a few flour streaks remaining. Also, ensure you’re measuring your flour correctly; spoon it into your measuring cup rather than scooping directly can help maintain lightness.
Are Biscoff Blondies safe for my pets or people with allergies?
Biscoff blondies contain ingredients like butter, eggs, and chocolate, which are unsafe for pets and may not be suitable for individuals with dairy, egg, or nut allergies. Always consider your guests’ dietary restrictions and preferences. If you’re looking to make them allergy-friendly, consider swapping with vegan butter and egg replacements while carefully substituting each ingredient for a similar texture.
