Ingredients
List of Ingredients
- 1 cup unsalted butter, melted
- 1 cup brown sugar
- 1/2 cup granulated sugar
- 2 large eggs
- 2 teaspoons vanilla extract
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon salt

Measurement and Preparation Tips
To make the best Biscoff cookie butter blondies, use a kitchen scale for precise measuring. When measuring flour, spoon it into the cup, then level it off. This method prevents packing and ensures you don't use too much. Melt the butter gently to avoid burning. You can do this in a microwave or on the stove. Let the butter cool slightly before mixing in the sugars.
Key Ingredients and Substitutions
Biscoff cookie butter is the star of this recipe. It adds a rich flavor. If you can't find it, you can use any other cookie spread, like Speculoos or even Nutella. The butter gives moisture, while the eggs help bind the mixture. For a lighter version, you can use unsweetened applesauce in place of half the butter. Brown sugar adds depth and moisture, while granulated sugar gives sweetness and structure. If you're out of eggs, try using flax eggs or applesauce as a substitute.

Step-by-Step Instructions
Prepping the Baking Pan
First, preheat your oven to 350°F (175°C). Grab a 9x9 inch baking pan. Line it with parchment paper. Leave some paper hanging over the edges. This makes it easy to lift out the blondies later.
Mixing Wet Ingredients
In a large mixing bowl, pour in 1 cup of melted unsalted butter. Add 1 cup of brown sugar and 1/2 cup of granulated sugar. Whisk them together until the mixture is smooth. Next, crack in 2 large eggs, one at a time. Mix well after each egg. Finally, stir in 2 teaspoons of vanilla extract for that rich flavor.
Combining Dry Ingredients
In another bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking powder, and 1/2 teaspoon of salt. This helps the blondies rise and adds a nice texture. Gradually mix these dry ingredients into your wet mixture. Stir until just combined. Be careful not to overmix, or your blondies may turn out tough.
Folding in Biscoff and Baking
Now it’s time to fold in 1 cup of Biscoff cookie butter. This will give your blondies a lovely flavor. Use a spatula to mix until the cookie butter is evenly spread throughout the batter. Then, gently fold in 1/2 cup of crushed Biscoff cookies. This adds a crunchy texture. Pour the batter into the prepared baking pan. Smooth the top with your spatula.
Cooling and Cutting the Blondies
Bake the blondies for 25-30 minutes. You will know they are done when the edges are golden brown. Insert a toothpick into the center. If it comes out clean, they are ready. Let the blondies cool in the pan for about 10 minutes. Then, lift them out using the parchment paper. Let them cool completely on a wire rack. Once cool, cut them into squares and serve. Enjoy your sweet treat!
Tips & Tricks
Achieving the Perfect Texture
To get that soft and chewy texture, use room temperature eggs. Cold eggs may not mix well with the butter and sugars. Also, don't overmix the batter after adding the flour. Stir just until combined. This helps keep your blondies light and fluffy.
Baking Time Adjustments
The baking time for Biscoff cookie butter blondies can vary. Use a toothpick to check if they are done. If it comes out clean, they’re ready. If you like a gooey center, take them out a bit early. Just remember, they will firm up as they cool.
Serving Suggestions
These blondies are great on their own, but you can elevate them. Try drizzling extra Biscoff cookie butter on top. For added flair, sprinkle crushed Biscoff cookies or even nuts. Serve them warm with a scoop of vanilla ice cream for a tasty treat. Enjoy every bite!
Pro Tips
- Use Room Temperature Ingredients: Bringing eggs and butter to room temperature helps them blend better, creating a smoother batter.
- Don't Overmix the Batter: Mix until just combined to keep the blondies soft and chewy. Overmixing can lead to tough blondies.
- Check for Doneness: Insert a toothpick into the center; it should come out with a few moist crumbs, not wet batter, for perfect blondies.
- Customize Your Toppings: Feel free to add nuts or chocolate chips for extra flavor and texture, tailoring the blondies to your taste.
Variations
Adding Nuts or Chocolate Chips
You can boost the flavor and texture of your blondies by adding nuts or chocolate chips. Just fold in 1/2 cup of your favorite nuts, like walnuts or pecans, into the batter. If you love chocolate, add 1/2 cup of chocolate chips instead. This adds a rich taste and a delightful crunch. Both options make the blondies even more fun to eat.
Gluten-Free Adaptations
Want to make gluten-free blondies? You can swap the all-purpose flour for a gluten-free flour blend. Look for a blend that includes xanthan gum. This helps the blondies keep their structure. You can use the same amount of gluten-free flour as regular flour. Your blondies will still be soft and tasty.
Flavor Infusions with Different Spreads
Biscoff cookie butter is amazing, but you can try other spreads too. Nut butters like almond or peanut butter can add a nutty twist. Chocolate spreads give your blondies a rich flavor. Just replace the Biscoff cookie butter with the spread of your choice. This way, you can create new flavors with every batch.
Storage Info
Best Practices for Storing Blondies
To keep your Biscoff cookie butter blondies fresh, store them in an airtight container. This step protects them from air and moisture. You can place parchment paper between layers to keep them from sticking. Keep the container at room temperature for the best taste. Avoid the fridge, as cold can alter their texture.
Freezing Instructions
If you want to save some blondies for later, freezing is easy. Wrap each blondie in plastic wrap tightly. Then, place them in a freezer bag or container. Be sure to label the bag with the date. They can stay in the freezer for up to three months. When you’re ready to enjoy them, let them thaw at room temperature.
How Long Do They Last?
Biscoff cookie butter blondies last about five days at room temperature. Make sure they stay covered to keep them soft and chewy. If you freeze them, they can last much longer, as mentioned before. Enjoy them fresh for the best flavor, but they still taste great even after a few days!
FAQs
Can I use a different nut butter?
Yes, you can use other nut butters. Try almond or peanut butter. Each type gives a unique taste. Make sure it's smooth for the best results. If you pick a flavored nut butter, adjust the sugar as needed.
How do I know when my blondies are done?
Check the edges of the blondies. They should be golden brown. Insert a toothpick in the center. If it comes out clean, they are ready. If there is wet batter, they need more time. Typically, they bake for 25 to 30 minutes.
Can I make these ahead of time?
Absolutely! You can bake them a day or two in advance. Store them in an airtight container to keep them fresh. You can also freeze them for up to three months. Just thaw them at room temperature before serving.
What are some fun serving ideas?
Serve blondies on a wooden board for a rustic touch. Drizzle more Biscoff cookie butter on top for extra flavor. You can also crumble whole Biscoff cookies over them. For a fun twist, add a scoop of vanilla ice cream on the side.
