Step‑by‑Step Instructions for Biscoff Blondies
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven heats up, grease an 9×9-inch baking pan with a light coating of cooking spray or line it with parchment paper for easy removal. Ensuring the pan is ready will allow your Biscoff blondies to bake evenly and come out perfectly shaped.
Step 2: Melt the Butters
In a saucepan over low heat, combine the unsalted butter and Biscoff cookie butter. Stir the mixture gently until it melts and becomes smooth, taking about 3-5 minutes. Once melted, remove it from the heat and let it cool for around 5 minutes, allowing it to reach a warm temperature without solidifying before mixing with other ingredients.
Step 3: Combine Sugars
In a mixing bowl, add the slightly cooled melted butter mixture, then whisk in brown sugar until completely smooth and blended. This should take about 1-2 minutes and create a shiny texture. Getting this mixture right is essential for the chewy consistency of your Biscoff blondies, so make sure there are no lumps before moving on.
Step 4: Add Eggs
Incorporate the large eggs, adding one at a time to the mixture. Whisk each egg thoroughly until it is fully incorporated before adding the next. This should take about 1-2 minutes for each egg. This step is crucial for creating a rich texture in your blondies, binding all the ingredients together beautifully.
Step 5: Mix in Vanilla
Stir in the vanilla extract to the egg and sugar mixture, blending well for about 30 seconds. The aroma of vanilla should fill your kitchen, uplifting the entire batter and enhancing the flavors of your Biscoff blondies. It’s a simple addition, but it makes a noticeable difference in taste.
Step 6: Combine Dry Ingredients
In a separate bowl, sift together the all-purpose flour, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, using a spatula to mix gently until just combined, about 1-2 minutes. Avoid overmixing; you want the batter to remain thick yet smooth for that chewy blondie texture.
Step 7: Fold in Add-ins
Gently fold in the white chocolate chips and crushed Biscoff cookies. This should take about 30 seconds, and your batter will start to look delightful and chunky. Each bite of your Biscoff blondies will be filled with creamy chocolate and crunchy cookie pieces, elevating its delightful texture.
Step 8: Spread and Bake
Pour the prepared batter into the greased baking pan, spreading it evenly with a spatula. Place the pan in the preheated oven, baking the Biscoff blondies for 25-30 minutes. They are ready when the edges are lightly golden and a toothpick inserted into the center comes out mostly clean with a few crumbs sticking to it.
Step 9: Cool and Serve
Once baked, remove the pan from the oven and allow the blondies to cool in the pan for about 10 minutes. Then, carefully transfer them to a wire rack to cool completely before cutting them into squares. This cooling process is critical for achieving the perfect texture, ensuring your Biscoff blondies are soft yet firm enough to slice beautifully.

How to Store and Freeze Biscoff Blondies
Room Temperature: Keep your Biscoff blondies in an airtight container at room temperature for up to 3 days to maintain their chewy texture and delicious flavor.
Fridge: Storing them in the fridge can extend their freshness; they’ll last for up to a week. Just remember to wrap them well to prevent drying out.
Freezer: For longer storage, freeze the blondies in a single layer on a baking sheet, then transfer to an airtight container or zip-top bag. They’ll stay good for up to 3 months.

Biscoff Blondies Recipe FAQs
How do I choose ripe ingredients for my Biscoff Blondies?
Absolutely! When selecting your ingredients, pick unsalted butter that is soft but not melted, as this provides the right moisture. For the Biscoff cookie butter, look for a smooth texture without separation; the jar should have an even color and consistency. Fresh large eggs should be free of cracks and have a clean, unblemished shell for the best binding quality.
How should I store my Biscoff Blondies, and for how long?
You can keep your Biscoff blondies in an airtight container at room temperature for up to 3 days. If you want to prolong their freshness, storing them in the refrigerator wrapped well will ensure they last for up to a week. Just be aware that refrigeration may slightly alter their chewy texture.
Can I freeze Biscoff Blondies, and how do I do it?
Absolutely, you can freeze your Biscoff blondies! Start by cutting them into squares and laying them out in a single layer on a baking sheet. Freeze for about 1-2 hours, then transfer them to an airtight container or a zip-top freezer bag. They will keep well for up to 3 months. To defrost, simply leave them in the fridge overnight or microwave for 10-15 seconds to warm back up.
What should I do if my Biscoff Blondies are too dry?
Very! If your Biscoff blondies turn out dry, it may be due to overmixing the batter. To prevent this next time, mix just until incorporated after adding dry ingredients, and be sure to check for doneness a bit earlier than the recommended baking time. If they’re already baked, try serving them with a scoop of ice cream or a drizzle of warm Biscoff spread for added moisture and flavor!
Are there any dietary considerations for Biscoff Blondies for pets or allergies?
For sure! Biscoff cookies typically contain wheat, sugar, and spices that might not be safe for pets; avoid giving them to dogs or other animals. If allergies are a concern, make sure to check the packaging of all ingredients for potential allergens like gluten or soy. For a nut-free option, substitute Biscoff cookie butter with sunflower seed butter, keeping in mind the flavor will change!
