Step‑by‑Step Instructions for Brown Butter Biscoff Blondies
Step 1: Preheat the Oven
Start this delightful adventure by preheating your oven to 350°F (175°C). While the oven warms up, line an 8×8 baking dish with parchment paper, allowing for easy removal after baking. This initial step sets the stage for the cozy warmth that will soon fill your kitchen as you make these irresistible Brown Butter Biscoff Blondies.
Step 2: Brown the Butter
In a medium saucepan over medium heat, melt ½ cup of unsalted butter. Keep stirring frequently for about 6-10 minutes until the butter transforms into a rich amber color and releases a nutty aroma. Be vigilant; once you see brown specks forming, remove it from heat to avoid burning. Let the brown butter cool slightly while you gather the next ingredients.
Step 3: Combine Wet Ingredients
In a mixing bowl, combine the slightly cooled brown butter and 1 cup of packed brown sugar, mixing until the mixture is smooth and glossy. Next, add in 1 egg and 1 egg yolk along with ½ cup of Biscoff spread. Stir everything together until well combined, creating a luscious, flavorful base for the blondies.
Step 4: Add the Dry Ingredients
To the wet mixture, gently incorporate a pinch of salt and 1 cup of all-purpose flour. Stir until just combined; be careful not to over-mix. The texture should remain thick and gooey, perfect for those chewy Brown Butter Biscoff Blondies you crave. Then, fold in ½ cup of chopped chocolate, allowing lush melted pockets in each bite.
Step 5: Prepare for Baking
Pour the decadent batter into the lined baking dish, smoothing the top for even baking. Optionally, sprinkle additional chocolate and crushed Biscoff cookies on top for that perfect finishing touch. This step not only enhances the flavor but also adds a delightful crunch that everyone’s sure to love.
Step 6: Bake to Perfection
Bake your Blondies in the preheated oven for 20-25 minutes. Look for the edges to turn light brown, while the center remains slightly soft—it will continue to set as it cools. To ensure doneness, insert a toothpick; if it comes out clean, you know your Brown Butter Biscoff Blondies are ready for cooling.
Step 7: Cool and Slice
Once baked, allow the blondies to cool in the pan for at least 30 minutes before slicing. For best results, consider letting them set for a few hours. This waiting period enhances the chewy texture and deepens the flavor, giving you the most satisfying finish to these delightful treats.

Expert Tips for Brown Butter Biscoff Blondies
-
Brown Butter Mastery: Watch closely as butter browns; it should smell nutty and have small brown specks. Remove from heat promptly to avoid burning.
-
Avoid Over-Mixing: Stir the batter gently with a spatula until just combined; over-mixing can lead to dense blondies instead of the desired chewy texture.
-
Check for Doneness: Start checking at 20 minutes; the edges should be light brown and the center slightly soft. This ensures your Brown Butter Biscoff Blondies remain gooey.
-
Use Proper Pans: Light-colored metal baking dishes promote even baking, preventing the edges from browning too quickly compared to darker pans.
-
Let Them Cool: Allow the blondies to cool for at least 30 minutes before slicing, or up to a few hours for the best texture and flavor development.

Room Temperature: Store your blondies in an airtight container at room temperature for up to 5 days to maintain their chewy texture.
Fridge: For extended freshness, refrigerate the blondies in an airtight container for up to 7 days, allowing them to retain their moistness.
Freezer: If you want to save some for later, freeze the blondies wrapped tightly in plastic wrap and then in foil for up to 3 months. Thaw at room temperature or warm them slightly in the microwave.
Reheating: To enjoy your Brown Butter Biscoff Blondies warm, microwave individual pieces for about 10-15 seconds until gooey and delightful!

Brown Butter Biscoff Blondies Recipe FAQs
What’s the best way to choose ripe ingredients for this recipe?
Absolutely! For the best flavor, use fresh, high-quality unsalted butter and pack your brown sugar tightly to ensure sweetness. When selecting Biscoff cookies, choose those that are not broken or excessively crumbled, as they should hold up as a crunchy topping.
How should I store my Brown Butter Biscoff Blondies?
To keep your blondies fresh, store them in an airtight container at room temperature for up to 5 days. If you want to prolong their shelf life, refrigerate them for up to 7 days. Always allow them to cool completely before sealing to avoid moisture buildup.
Can I freeze the blondies for later enjoyment?
Yes! These blondies freeze beautifully. Wrap them tightly in plastic wrap, then place them in a heavy-duty freezer bag. They can be frozen for up to 3 months. When you’re ready to enjoy, simply thaw them at room temperature or warm them in the microwave for about 10-15 seconds.
What should I do if my blondies turn out too cakey?
No problem! If your blondies are cakey, it’s likely due to over-mixing the batter or using the wrong flour measurement. To remedy this in future batches, gently fold in ingredients just until combined to maintain the chewy texture. Additionally, using a kitchen scale for precise measurements can help achieve that perfect fudgy consistency you desire.
Are these blondies safe for those with nut allergies?
Good question! While the Brown Butter Biscoff Blondies themselves don’t contain nuts, be cautious about the Biscoff spread and chocolate you use, as they might be processed with nuts. Always check labels carefully if you or someone you’re serving has a nut allergy to ensure safety.
What can I do if I don’t have chocolate chips?
Very! If you don’t have chocolate chips on hand, you can substitute them with chopped chocolate bars, cocoa nibs, or even leave them out entirely if you prefer a lighter version. Alternatively, consider adding chopped nuts or extra Biscoff cookies for added texture and flavor!
