Ingredients Needed for Biscoff Brownies

Brownie Mix: Use your favorite boxed brownie mix for an easy start. A mix with a rich, fudgy consistency works best for this recipe.
Eggs: Adds richness and structure to the brownies, giving them that perfect balance between cakey and fudgy.
Salted Butter: Instead of oil, butter adds depth and a subtle salty flavor that enhances the chocolate.
Milk: This helps the brownie mix come together and adds a slight creaminess.
Milk Chocolate Chips: These melt into gooey pockets within the brownies. You can substitute semi-sweet if you prefer a less sweet brownie.
Cookie Butter: Adds a layer of creamy, spiced goodness. You’ll spread this over the brownie layer, making every bite a bit indulgent.
Biscoff Cookies: These bring crunch and even more of that caramelized Biscoff flavor to the brownies. Roughly chop them for the best texture.

Tips & Tricks

Use Room Temperature Ingredients: Mixing with room temperature eggs and butter helps the batter come together more smoothly.
Don’t Overbake: These brownies are best when they’re still fudgy in the center, so pull them out when a toothpick comes out with a few moist crumbs.
Layer Carefully: When spreading the final brownie layer, go slow and gentle to avoid disturbing the cookie butter layer.
Let Them Cool Completely: It’s tempting to dig in right away, but letting them cool fully makes slicing cleaner and easier.
Add Extra Crunch: Save a few Biscoff cookies to crush and sprinkle on top just before serving for a little extra crunch.

FAQ

Can I use a homemade brownie mix instead of boxed?
Absolutely! Just make sure the recipe you use yields a fudgy texture rather than cakey for the best result.
Can I substitute something for the cookie butter?
If you can’t find cookie butter, a creamy peanut butter or almond butter will work, but the flavor will be different—less spiced and more nutty.
What’s the best way to layer the cookie butter without making a mess?
Use a spoon to dollop small amounts across the brownie layer, then gently spread it out with a spatula. Starting with small dollops helps keep it even.
Can I make these in an 8×8 pan instead?
You can, but the brownies will be much thicker, and you’ll need to increase the baking time. Keep an eye on them as they bake.
Are there other cookies that would work on top?
Sure! Try graham crackers, chocolate chip cookies, or even chopped Oreos for a twist.
Can I add nuts or other mix-ins?
Yes! Chopped nuts, caramel bits, or extra chocolate chips are all great options.
Why did my brownies turn out crumbly?
If the brownies are too crumbly, they may have been overbaked. Stick to the baking time and look for a few moist crumbs on the toothpick.
Can I double this recipe?
Yes, but you’ll need a much larger pan, or you can bake them in two separate 9×13 pans.
Do I need to refrigerate these?
You can keep them at room temperature for a few days, but refrigerating them will extend their freshness.
