The first time I baked these Delicious Biscoff Blondies with Cookie Butter Topping, I was instantly hooked. It was one of those moments where you pause, take a deep breath, and just smile because you know you’re onto something truly special.

Years ago, when I was knee-high to a grasshopper, my grandma used to make simple butter cookies that filled the house with warmth. But these blondies? They’re like a grown-up, richer cousin that I wish I’d discovered sooner. I stumbled upon the idea during a rainy weekend, trying to recreate that comfort with a modern twist—cookie butter on top, no less! Honestly, my family couldn’t stop sneaking them off the cooling rack (and I can’t really blame them). It’s dangerously easy to eat one after another.

These blondies are perfect for potlucks, a sweet treat for your kids, or just a little something to brighten up your Pinterest cookie board.

What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these you’ll find in your pantry, and substitutions are easy if you need them.

• Unsalted butter, 1 cup (227g), melted (adds richness and moisture)
• Light brown sugar, 1 cup (200g), packed (for that deep caramel flavor)
• Granulated sugar, ¼ cup (50g) (balances sweetness and texture)
• Large eggs, 2, room temperature (helps bind and create that chewy texture)
• Pure vanilla extract, 2 teaspoons (boosts flavor)
• All-purpose flour, 1 ½ cups (190g) (for structure)
• Baking powder, 1 teaspoon (for a slight lift)
• Ground cinnamon, ½ teaspoon (enhances the warm spice profile)
• Salt, ¼ teaspoon (balances the sweetness)
• Biscoff cookie butter, ½ cup (125g) (for that signature topping; use Lotus brand if you want the classic flavor)

Ingredient tips: Use unsalted butter so you can control the salt level precisely. For the cookie butter, Lotus is my personal favorite—creamy, with just the right amount of spice. If you want to try a dairy-free version, swap the butter for coconut oil and use a dairy-free cookie butter alternative.

For a gluten-free twist, you can substitute the flour with a 1:1 gluten-free baking flour. In summer, fresh berries make a great addition stirred into the batter for a fruity surprise.

Equipment Needed

• 8×8-inch (20×20 cm) baking pan (preferably non-stick or lined with parchment paper for easy removal)
• Mixing bowls (medium and large size)
• Whisk and rubber spatula (for mixing and folding)
• Measuring cups and spoons (for precise ingredient amounts)
• Electric mixer (optional, but handy for beating eggs and sugar)
• Microwave-safe bowl or small saucepan (to melt butter and cookie butter topping)

If you don’t have an electric mixer, a sturdy whisk and some elbow grease will do just fine. I’ve baked these blondies in glass and metal pans—just watch your baking time as glass can take a little longer. For budget-friendly equipment, parchment paper is a game-changer, and you can reuse it multiple times.

Preparation Method

1. Preheat your oven to 350°F (175°C). Line your 8×8-inch pan with parchment paper, letting some overhang for easy blondie removal later. This usually takes about 10 minutes total including prep.
2. Melt the butter. In a microwave-safe bowl or over low heat on the stove, melt 1 cup (227g) unsalted butter until smooth. Let it cool slightly while you prep other ingredients.
3. Mix sugars and eggs. In a large bowl, whisk together 1 cup (200g) light brown sugar and ¼ cup (50g) granulated sugar. Add 2 large eggs, one at a time, whisking well after each addition. Then stir in 2 teaspoons pure vanilla extract. This step should take 3-5 minutes to get a smooth, glossy mixture.
4. Add melted butter. Slowly pour in the slightly cooled melted butter, whisking continuously to combine. The batter will be thick and shiny—if it looks curdled, don’t worry, just keep whisking gently until smooth.
5. Combine dry ingredients. In a separate bowl, sift together 1 ½ cups (190g) all-purpose flour, 1 teaspoon baking powder, ½ teaspoon ground cinnamon, and ¼ teaspoon salt. Sifting helps avoid lumps and ensures even distribution.
6. Fold dry into wet. Gradually add the dry ingredients into the wet mixture using a rubber spatula. Fold gently until just combined—don’t overmix or the blondies can get tough. The batter should be thick with no visible flour patches.
7. Pour batter into the pan. Spread the batter evenly in the prepared pan, smoothing the top with your spatula.
8. Prepare cookie butter topping. In a microwave-safe bowl, warm ½ cup (125g) Biscoff cookie butter for 20-30 seconds until soft enough to drizzle but not liquid. Drizzle or spoon the cookie butter over the blondie batter. Using a knife or skewer, gently swirl the cookie butter through the batter for a marbled effect.
9. Bake. Place the pan in the oven and bake for 25-30 minutes. Start checking at 25 minutes by inserting a toothpick in the center—it should come out with a few moist crumbs but not wet batter. The edges will be golden and slightly pulling away from the pan.
10. Cool completely. Let the blondies cool in the pan on a wire rack for at least 1 hour before cutting. This helps them set perfectly and keeps the texture chewy and tender.

Pro tip: If you notice the cookie butter topping gets too firm to swirl, just pop it back in the microwave for 10 seconds. Also, don’t rush cooling—warm blondies can be crumbly when cut.

Cooking Tips & Techniques

One thing I’ve learned over countless batches is the importance of temperature—eggs and butter at room temperature mix more evenly, giving you that smooth, chewy texture. If your eggs are cold, give them a quick warm water bath before mixing.

Don’t be tempted to overmix the batter once the flour is added. Overworking gluten is the enemy of tender blondies, and you’ll end up with something cakier and less chewy.

Swirling the cookie butter topping is a fun step but tricky if it’s too cold or too hot. I’ve found warming it gently in short bursts keeps it pliable without melting completely, which gives you a gorgeous marbled look and a perfect balance of flavor in every bite.

Timing is everything here. Keep an eye on your oven since every oven heats differently. I usually set a timer for 25 minutes but check early to avoid overbaking. The blondies should feel set but still soft in the center.

When multitasking, prepare your cookie butter topping while the blondie batter rests for a minute—that way you won’t be scrambling at the last second.

Variations & Adaptations

• Nutty Twist: Fold in ½ cup chopped pecans or walnuts into the batter for extra crunch and depth.
• Chocolate Lover’s: Add ¾ cup chocolate chips or chunks for melty pockets of chocolate goodness.
• Gluten-Free: Use a 1:1 gluten-free baking flour blend. The texture will be slightly softer but just as delicious.
• Dairy-Free: Swap butter for coconut oil and use a dairy-free cookie butter alternative. The flavor shifts but stays delightfully rich.
• Seasonal Flair: In autumn, add a pinch of nutmeg and cloves to the batter. In summer, try adding fresh raspberries or chopped strawberries for bursts of freshness.

Personally, I once tried a version with a swirl of peanut butter and a sprinkle of sea salt on top—it was an unexpected hit that added a salty-sweet edge. Don’t be afraid to get creative with your toppings and mix-ins!

Serving & Storage Suggestions

These blondies are best served at room temperature, allowing the cookie butter topping to be soft and luscious. For a little extra indulgence, warm a piece slightly and add a scoop of vanilla ice cream—dangerously good!

Pair these blondies with a cup of coffee or a glass of cold milk for a nostalgic treat. They’re great for dessert tables, afternoon snacks, or as a sweet finish to casual dinners.

To store, keep them in an airtight container at room temperature for up to 3 days or in the fridge for up to a week. I like chilling leftovers for a denser, fudgier bite. For longer storage, wrap tightly and freeze for up to 2 months. Thaw overnight in the fridge and warm slightly before serving.

Flavors actually deepen after a day or two—if you can wait that long! Just be sure to keep them well covered to prevent drying out.

Nutritional Information & Benefits

Each serving of these Biscoff blondies packs roughly 280-320 calories, depending on portion size and mix-ins. They provide a comforting source of quick energy from sugars and butter, making them a delightful occasional treat.

Key ingredients like cinnamon add antioxidants, while the modest egg content contributes protein. Using real butter brings in some fat-soluble vitamins, but keep portions moderate to enjoy guilt-free.

For those with dietary needs, this recipe can be adapted to gluten-free or dairy-free versions without sacrificing much in flavor or texture. Just be mindful of nut allergies if adding mix-ins.

From a wellness perspective, I see these blondies as a joyful indulgence—sometimes nourishing the soul is just as important as the body!

FAQs About Biscoff Blondies Recipe

Can I make these blondies vegan?

Yes! Replace butter with coconut oil and use flax eggs (1 tablespoon ground flaxseed + 3 tablespoons water per egg) instead of regular eggs. Use a vegan cookie butter to keep the flavor on point.

How do I store leftover blondies?

Store in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week. For longer storage, freeze wrapped tightly for up to 2 months.

Can I use crunchy Biscoff cookie butter instead of smooth?

You can, but the topping might be a bit chunkier and harder to swirl. I recommend smoothing it first or warming it gently to help with spreading.

Make sure they are completely cooled (ideally chilled) before cutting. Use a sharp knife and wipe it clean between cuts for clean edges.
