Step‑by‑Step Instructions for Biscoff Blondies Chewy Cookie Butter Dessert Bars
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C) and grease a 9x13 inch baking pan, or line it with parchment paper, allowing some overhang. This will help you lift the blondies out easily once baked. As the oven warms up, you can start combining your ingredients for the Biscoff Blondies.
Step 2: Mix Sugars and Butter
In a large mixing bowl, pour in the melted unsalted butter, packed brown sugar, and granulated sugar. Using a whisk, mix everything until the blend is completely smooth and glossy, which should take about a minute. This step creates a sweet and rich base for your chewy cookie butter dessert bars.
Step 3: Add Eggs and Vanilla
Next, crack in two large eggs, adding them one at a time. Whisk between each addition until they are fully incorporated into the mixture. Stir in a tablespoon of vanilla extract for an aromatic boost, ensuring it mingles well with the other ingredients. You'll see the batter becoming creamy and luscious.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. This dry mixture is essential for creating the structure of the blondies. After it’s well blended, you’re ready to unify the wet and dry components to create a beautiful batter that forms the heart of your Biscoff Blondies.
Step 5: Combine Wet and Dry Mixtures
Slowly fold the dry mixture into the wet ingredients using a spatula or wooden spoon, mixing until just combined. Be careful not to overmix; some flour pockets are okay. This gentle folding ensures your Biscoff Blondies will be light yet chewy—just how we like them!
Step 6: Fold in Biscoff Cookie Butter
Now, gently fold in one cup of Biscoff cookie butter until the batter is smooth but still has swirls of the cookie butter for that marbled look. The cookie butter adds a unique flavor and richness to your blondies that truly stands out. You’ll love the aroma that fills your kitchen as you mix!
Step 7: Add Crushed Cookies
Incorporate the crushed Biscoff cookies into the batter with care, making sure they are evenly distributed. Reserve a handful of cookies to sprinkle on top later for added texture and flavor. This step will turn your dessert bars into an indulgent treat that everyone will adore.
Step 8: Transfer to Pan
Pour the thick batter into your prepared baking pan, spreading it evenly. Use an offset spatula to smooth the surface if needed. Sprinkle the reserved crushed Biscoff cookies generously on top. This will create a crispy topping that contrasts beautifully with the chewy center of your blondies.
Step 9: Bake for Perfection
Place the baking pan in your preheated oven and set a timer for 25-30 minutes. Keep an eye on them; they should be lightly golden around the edges. To check doneness, insert a toothpick in the center—aim for a few moist crumbs on it, avoiding overbaking to maintain the chewy texture of your Biscoff Blondies.
Step 10: Finish and Salt
Once baked, remove the blondies from the oven and sprinkle a pinch of sea salt over the top while they're still warm. The salt will enhance the sweetness and provide a lovely contrast. Let them rest in the pan, soaking in that rich flavor while cooling slightly.
Step 11: Cool and Cut
Allow the blondies to cool in the pan for about 15 minutes before using the parchment paper overhang to lift them out. Transfer the bars to a wire rack and allow them to cool completely. Once cool, cut them into squares and get ready to indulge in your freshly baked Biscoff Blondies Chewy Cookie Butter Dessert Bars!
