Ingredients
- Butter: Choose high quality unsalted butter for the right base flavor Browning the butter makes the blondies extra nutty and rich
- Brown sugar: The subtle molasses flavor pairs perfectly with Biscoff and makes the bars extra chewy Go for dark brown sugar if possible
- Eggs: Large eggs hold everything together and add moisture Room temperature eggs mix more evenly
- Biscoff spread: Smooth and creamy this is the backbone of the recipe Use the name brand for maximum spiced flavor
- Crushed Biscoff cookies: These bring in a surprise crunch in every bite Aim for some bigger chunks for texture
- All purpose flour: Standard flour keeps things chewy not cakey Sift it if lumpy
- Baking powder: This leavening agent helps the blondies rise just enough Make sure yours is fresh for fluffy results
- Salt: Just a little balances the sweetness Use fine sea salt for even seasoning
- White chocolate chips: These deliver creamy sweetness in every bite Always pick real white chocolate made with cocoa butter for best flavor
- Extra crushed Biscoff cookies: Adds a decorative finish and a final punch of spice on top
Step by Step Instructions
- Melt the Butter:
- Gently melt the butter in a small saucepan over medium heat For a deeper caramel flavor keep an eye on it as it sizzles and turns golden brown Swirl the pan often to avoid burning Cool for a few minutes before moving on
- Mix the Wet Ingredients:
- Pour the melted butter into a large bowl Add brown sugar and crack in the eggs Whisk vigorously until the mixture looks glossy and thick This helps dissolve the sugar and get a shiny top on your blondies Next spoon in the Biscoff spread and mix until smooth Fold in the roughly crushed Biscoff cookies
- Combine with Dry Ingredients:
- In a separate bowl whisk together flour baking powder and salt Slowly add this dry mix to the wet ingredients stirring gently Do not overmix or the blondies might turn dense Stop when you see just a streak of flour left
- Stir in White Chocolate:
- Now fold in the white chocolate chips They should be evenly spread throughout the batter saving a handful to sprinkle on top if you like
- Prepare the Pan:
- Line an 8 by 8 inch baking pan with parchment paper or grease it for easy release Scoop the thick batter into the pan using a spatula to level it out Sprinkle more crushed Biscoff cookies across the top for crunch and looks
- Bake:
- Heat your oven to 350 degrees Fahrenheit Place the pan on the middle rack and bake for about twenty eight minutes You are looking for a golden top and a tester inserted in the center to come out with moist crumbs not wet batter
- Cool and Slice:
- Once baked cool the blondies in the pan for at least fifteen minutes This helps set the bars so they slice neatly For cleaner edges use a sharp knife and wipe between cuts

Maybe my favorite touch here is the handful of Biscoff cookies folded in Their surprise crunch always reminds me of my childhood snack time with my grandma We would savor each bite and giggle over Cookie Butter fingers
Storage Tips
Keep your blondies in an airtight container at room temperature and they stay chewy for three to four days For longer storage pop them in the fridge and enjoy chilled If you want to freeze wrap bars individually and thaw as needed
Ingredient Substitutions
No white chocolate chips Milk or dark chocolate work just as well Got peanut butter instead of Biscoff Try it for a nutty variation If you are out of brown sugar make your own by mixing granulated sugar with a spoonful of molasses
Serving Suggestions
These blondies are perfect straight up but you can warm them briefly and add a scoop of vanilla ice cream or a swirl of whipped cream For special occasions drizzle with melted Biscoff spread or dip in melted white chocolate
