This spreadable goodness tastes just like those caramelized speculoos cookies you got on flights. The sweet, spiced aroma fills the kitchen, and just like that, your home smells as inviting as a bakery.

Ingredients

1 cup unsalted butter: This adds moisture and richness, giving the blondies that “just melted” texture we crave.
1 cup Biscoff cookie butter: This is the star of the show! It brings that caramelized flavor to the blondies and a subtle spice that is simply irresistible.
1 cup brown sugar: It adds that perfect touch of sweetness while giving our blondies a chewy texture.
2 large eggs: Essential for binding the ingredients and creating a lovely, soft crumb.
1 teaspoon vanilla extract: Because nothing beats the classic flavor of vanilla swirling through baked goods.
2 cups all-purpose flour: This is the backbone of our recipe, providing structure to the blondies.
1 teaspoon baking powder: Helps the blondies rise just a tad, so they’re not too dense.
1/2 teaspoon salt: Balances out the sweetness and enhances all those flavors.
1/2 cup white chocolate chips: Because we weren’t sweet enough already! These little gems add creamy pockets of happiness.
1/2 cup crushed Biscoff cookies: More texture and all the Biscoff flavor in delightful little crunches.

Pro Tip: Use fresh, high-quality ingredients for the best results. Old flour or stale baking powder? No thanks! And don’t you dare skimp on the cookie butter—let’s be real, it’s what makes this recipe shine!

How to Make It Step-by-Step

Now, put on your favorite music, pour yourself a nice cup of tea (or coffee, if you prefer), and let’s get our bake on!

Preheat Your Oven: Start by preheating your oven to 350°F (175°C). This is crucial, buddy; we want those blondies to rise beautifully!
Prep Your Baking Pan: Grab a 9×9-inch square baking pan and grease it, or line it with parchment paper. This will help ensure our blondies glide out of the pan without any drama.
Melt Butter and Biscoff: In a medium-sized saucepan, melt the unsalted butter and Biscoff cookie butter together over low heat. Stir occasionally until it’s all smooth and together, like a delightful team of superheroes. The aroma? Honestly, it’s heavenly.
Mix in Brown Sugar: Once melted, remove the saucepan from heat and let it cool slightly for about 5 minutes. Then, add that brown sugar in and whisk until everything looks velvety smooth.
Add Eggs and Vanilla: Crack those two large eggs right into the mixture and whisk until they’re fully incorporated. Smack of raw eggs aside, add in the vanilla extract and give it another good stir. How does it smell? If your kitchen is anything like mine, it smells divine about now!
Combine Dry Ingredients: In a separate large bowl, sift together the all-purpose flour, baking powder, and salt. This step prevents clumping and ensures a smooth batter. Seriously, don’t skip it!
Mix Wet and Dry Ingredients: Slowly add your sifted dry ingredients into the wet ingredients. Use a spatula or wooden spoon to gently combine them. Be careful not to overmix—no one wants dense blondies! We want them nice and soft.
Fold in Chocolate and Cookies: Once combined, lovingly fold in the white chocolate chips and crushed Biscoff cookies. Oh boy, you’re in for a treat! The texture of the cookie bits and the creaminess of the white chocolate is out of this world.
Pour into the Pan: Pour the blondie batter into the prepared baking pan, spreading it evenly with a spatula. Make sure it reaches all the corners, friends!
Bake: Pop that pan in the preheated oven and bake for about 25 to 30 minutes. Set a timer and try not to obsessively check while they bake. If you gently insert a toothpick into the center, it should come out clean or with just a few crumbs.
Cool Down: Allow the blondies to cool in the pan on a wire rack for about 10 minutes before gently removing them from the pan. Let them cool completely on the rack. Take a moment to breathe in that warm, sweet smell!
Slice and Serve: Once cooled, cut the blondies into squares. Trust me, you won’t be able to resist trying a piece immediately! Enjoy!

Tips for Best Results

Don’t Overmix: A gentle touch is key! Overmixing can lead to tough blondies rather than the soft, chewy delights we’re after.
Quality Ingredients: Choose high-quality butter and Biscoff cookie butter for the best flavor.
Cool Completely Before Cutting: If you dive in too soon, they might fall apart. Patience pays off in the form of clean slices!

Ingredient Substitutions & Variations

Nutty Addition: Feel free to throw in some chopped nuts like walnuts or pecans for an extra crunch.
Different Chocolate: Dark chocolate chips can replace white chocolate if that’s more your style. Because, why not?
Flipped Script: If you want a healthier spin, consider using whole wheat flour for a slight nutty flavor and increased fiber.
Vegan Option: Substitute the butter with coconut oil and use flax eggs instead of regular eggs (1 tablespoon ground flax mixed with 2.5 tablespoons water per egg).

Directions

Best served warm, these blondies pair wonderfully with a scoop of vanilla ice cream. Just imagine that delightful contrast of warm and cold! And if you ask me, these blondies and a rom-com? That’s perfection in a cozy evening right there.

How to Store and Reheat Leftovers

Remaining blondies can be stored in an airtight container at room temperature for 3-5 days (if they last that long!). If you love a warm treat, just pop them back in the microwave for about 10-15 seconds. The sugar will melt a bit, and you’ll have that gooey goodness again. If they start feeling too dry over time, a quick drizzle of cream can save the day!

Make-Ahead and Freezer Tips

These blondies can be made ahead of time! Just bake, let them cool, and then store them in the freezer for up to 3 months. When you’re ready to indulge, thaw them in the fridge overnight and warm them up when you’re ready to enjoy them.

Common Mistakes to Avoid

Baking Time: Don’t just set the timer and forget about them! Check for doneness around the 25-minute mark. Nobody wants overbaked blondies.
Greasing the Pan: Ensure you grease the pan well or use parchment paper, or you’ll be anxiously prying the blondies out.
Melted Butter: Remove from heat and allow to cool slightly before adding the eggs. If not, you risk scrambling the eggs—oops!

Frequently Asked Questions (FAQ)

Can I double this recipe?
Absolutely! Just bake in a larger pan and adjust the baking time accordingly. Start checking around the 30-35 minute mark.

Can I use regular butter instead of unsalted?
You can, but be mindful of your salt levels. If using salted butter, reduce the added salt to 1/4 teaspoon.

What’s the best way to crush Biscoff cookies?
You could use a food processor, but honestly, crushing them in a zip-top bag with a rolling pin can also be therapeutic!
