How to Make Brown Butter Biscoff Blondies
Step 1: Preheat the Oven
Preheat your oven to 350° F. This ensures it’s ready to bake your blondies perfectly.
Step 2: Prepare the Baking Dish
Line an 8×8 baking dish with parchment paper. This will make it easier to lift out the blondies once they are baked.
Step 3: Brown the Butter
In a saucepan over medium heat, melt the unsalted butter until it starts to foam. Stir continuously until it turns golden brown and develops a nutty aroma. Remove from heat and let cool slightly.
Step 4: Mix Wet Ingredients
In a mixing bowl, combine the brown sugar with the brown butter. Whisk until smooth. Add in the egg and egg yolk along with the Biscoff cookie butter. Mix until fully combined.
Step 5: Combine Dry Ingredients
In another bowl, whisk together flour and salt. Gradually fold this mixture into the wet ingredients using a rubber spatula. Be careful not to overmix.
Step 6: Add Chocolate
Gently fold in the chopped chocolate until evenly distributed throughout the batter.
Step 7: Bake
Pour the batter into your prepared baking dish and sprinkle some crushed Biscoff cookies on top. Bake in the preheated oven for about 20 minutes or until a toothpick inserted comes out clean.
Step 8: Cool and Serve
Let your Brown Butter Biscoff Blondies cool in the pan before lifting them out using the parchment paper. Cut into squares and enjoy!

How to Perfect Brown Butter Biscoff Blondies
To ensure your Brown Butter Biscoff Blondies turn out perfectly every time, consider these helpful tips.
-
Brown the Butter Carefully: Cook the butter until it turns golden brown, but watch closely to avoid burning. This enhances the nutty flavor.
-
Use Room Temperature Ingredients: Ensure your egg and Biscoff spread are at room temperature. This helps create a smoother batter.
-
Don’t Overmix: Mix just until combined to keep your blondies chewy. Overmixing can lead to a dense texture.
-
Check for Doneness: Insert a toothpick in the center; it should come out with a few moist crumbs for perfect fudginess.
-
Cool Completely Before Cutting: Allow the blondies to cool in the pan before cutting. This helps them set and makes slicing easier.

Common Mistakes to Avoid
When making Brown Butter Biscoff Blondies, it’s easy to overlook some key steps that can affect the outcome. Here are some common mistakes to watch out for.
- Ignoring butter temperature: Using cold butter can result in uneven mixing and texture. Always use room temperature butter for a smooth batter.
- Not measuring ingredients accurately: Improper measurements can lead to dry or overly wet blondies. Use a kitchen scale or proper measuring cups for accuracy.
- Overmixing the batter: Overmixing can cause tough blondies. Mix just until the flour is incorporated for a chewy texture.
- Skipping the parchment paper: Not lining your baking dish can cause sticking and make cleanup difficult. Always line with parchment paper for easy removal.
- Underbaking or overbaking: Both can lead to undesirable texture. Check for doneness a few minutes before the timer goes off.
