These. Dang. Blondies. SO GOOD! I think we should start a blondie fan club! Blondies are the vanilla version of brownies, and we’re totally obsessed. Especially with these Biscoff cookie butter blondies. This recipe came about after a very long flight with only 2 Biscoff cookies to satisfy our cravings. We wanted more! So why not take these cookies a step further and make the best bars to enjoy whenever and wherever? These Biscoff Cookie Butter Blondies are chewy, soft, buttery, rich in flavor, and super easy to make!

One Bowl Lovin!

All you need is one large bowl for these blondies. We baked them in a square 8×8 pan (lined with parchment paper of course), but you can use a 9×9 pan too! Even though these blondies are so desirable, let these cool in the pan for 10 minutes before cutting into them. Once they settle, we promise you’ll have the best tasting blondie bars that you could’ve ever imagined! (top off with more cookie butter if you’d like!)

the best and easiest cookie Butter Blondie recipe

key ingredients

Nutmeg: Our secret kick in these blondies! This adds a robust and boost of flavor into these bars. If you like this, you’d probably love a chai twist! Add 1 tsp of your favorite chai spice mix & you’ll really groove to these blondies.

Butter: Melted butter is the perfect consistency for these blondies. They make it easier to combine with the rest of the ingredients. For a vegan or dairy-free substitute, use coconut oil!

Cookie Butter: Not only does Biscoff have amazing cookies, but they also have their own cookie butter! Can’t find Biscoff? Nuccina and Trader Joes have amazing substitutes (which tastes exactly the same). Cookie butter isn’t only good for blondies, you can spread this on your banana, toast, oats, yogurt, or even blend this into your favorite smoothie. Although cookie butter can be pretty thick, if you microwave this for 10-15 seconds, you’d have a smooth (easy to mix-in) consistency.

Biscoff Cookies: The star of the show of course! Chop up Biscoff cookies and add them to your batter, or top off your blondies for a sweet crunch. We haven’t made our own biscoff cookies, but if you love epic cookie recipes, you’ll obsess over our Brown Butter Chocolate Chip Cookies!

Additional Toppings: BUTTERSCOTCH. Ever had butterscotch with cookie butter? It’s a sweet treat! Add butter scotch chips or even nuts into this batter.

Now, let’s get into these amazing bars!
