Step‑by‑Step Instructions for Fudgy Biscoff Brownies with Cookie Butter Center
Step 1: Prepare Cookie Butter
Begin by slightly melting the Biscoff cookie spread in the microwave for about 15-20 seconds, making it easier to work with. Spread it onto a piece of parchment paper in a thin layer and place it in the freezer for at least 2 hours to firm up, ensuring a beautifully gooey center for your fudgy Biscoff brownies.
Step 2: Preheat Oven
While the cookie butter is chilling, preheat your oven to 325°F (160°C). Grease an 8×8 inch baking pan with butter or line it with parchment paper, allowing for easy removal later. This step is crucial to ensure your fudgy brownies cook evenly and lift out perfectly.
Step 3: Melt Chocolate
In a medium saucepan, combine the chopped semi-sweet chocolate and unsalted butter over low heat. Stir continuously for about 5 minutes until everything is melted and smooth. Remove from heat and let it cool slightly before incorporating it into the brownie mixture for that rich chocolatey goodness.
Step 4: Mix Wet Ingredients
In a large mixing bowl, whisk together the large eggs, egg yolk, and white granulated sugar for about 5 minutes until the mixture is light and fluffy. Add in the pure vanilla extract and canola oil, mixing until fully combined. This fluffy mixture will give your fudgy Biscoff brownies their delightful texture.
Step 5: Combine Mixtures
Carefully fold the cooled chocolate mixture into the egg mixture using a spatula until just combined. Then, gradually add the all-purpose flour, cocoa powder, cornstarch, and salt, stirring gently until no dry ingredients remain. Finally, fold in the Biscoff cookie pieces and mini chocolate chips, ensuring an even distribution.
Step 6: Layer Brownies
Pour half of the brownie batter into your prepared baking pan, smoothing it out evenly. Carefully place the frozen Biscoff cookie butter layer on top, then spoon the remaining batter over it. Gently spread the batter to cover the cookie butter entirely. Top with crushed Biscoff cookies for that extra crunch and flavor.
Step 7: Bake
Bake the fudgy Biscoff brownies in the preheated oven for 40-50 minutes, or until the edges are set but the center is slightly underbaked. A toothpick should come out with a few moist crumbs. Let them cool completely in the pan on a wire rack before slicing, allowing all those delicious layers to meld together perfectly.

Storage Tips for Fudgy Biscoff Brownies
- Room Temperature: Store your fudgy Biscoff brownies in an airtight container at room temperature for up to 4 days to maintain their deliciously soft texture.
- Refrigerator: If you prefer a firmer brownie, chill them in the fridge for up to a week, making sure to seal them securely to prevent drying out.
- Freezer: For longer storage, freeze the brownies in a single layer in an airtight container for up to 30 days. Thaw them at room temperature for about an hour before enjoying.
- Reheating: To enjoy warm brownies again, gently heat individual pieces in the microwave for 10-15 seconds, just until they’re warmed through, allowing that gooey cookie butter center to shine!
Expert Tips for Fudgy Biscoff Brownies
- Freeze Cookie Butter: Ensure the Biscoff cookie spread is frozen for easier layering; it melts rapidly during baking.
- Don’t Overmix: Gently fold the batters to avoid tough brownies; overmixing can lead to a dense texture instead of fudgy.
- Check Baking Time: Monitor closely towards the end; the brownies should be slightly underbaked in the center for that gooey texture.
- Spoon Flour Correctly: Remember to spoon flour into the measuring cup instead of scooping to prevent compacting, leading to denser brownies.
- Let Them Cool: Allow the brownies to cool completely in the pan before slicing; this helps them set up perfectly for that ideal fudgy experience.
- Customize Flavors: Feel free to mix in different types of chocolate chips or even a dash of sea salt on top for a delightful contrast in flavors!
Make Ahead Options
These fudgy Biscoff brownies are perfect for busy home cooks looking to save time on dessert prep! You can prepare the brownie batter and refrigerate it up to 3 days in advance, ensuring fresh brownies whenever you crave them. Simply mix everything together and store it in an airtight container. For the cookie butter center, freeze the prepared layer on parchment paper for up to 24 hours. When you’re ready to bake, just pour half the batter into your pan, layer it with the frozen cookie butter, cover with the remaining batter, and bake as instructed. This way, you’ll enjoy deliciously fudgy brownies with all the wonderful Biscoff flavors without the last-minute rush!

Fudgy Biscoff Brownies Recipe FAQs
How do I know if the Biscoff cookie spread is ripe or good to use?
Absolutely! Look for a smooth, creamy texture and a warm, spiced aroma. If you see any dark spots or an unusual separation, it’s best to replace it. Fresh Biscoff cookie spread should be a uniform color and the flavors should be vibrant and enticing!
What’s the best way to store leftover brownies?
Very! Store your fudgy Biscoff brownies in an airtight container at room temperature for up to 4 days. If you want to keep them longer, pop them in the fridge where they can last up to a week while remaining soft and delicious. Just remember, they love to stay cozy and sealed!
Can I freeze Biscoff brownies? If so, how?
For sure! To freeze, allow the brownies to cool completely. Then cut them into squares and arrange them in a single layer in an airtight container, separating layers with parchment paper. They can be frozen for up to 30 days. When ready to enjoy, let them thaw at room temperature for about an hour, or warm them gently in the microwave for a delicious treat!
What if my brownies come out too dry or crumbly?
Don’t fret! If your brownies turn out dry, it might be due to overbaking. Aim for that slightly underbaked center; they will continue to cook in the pan afterward. Keep an eye on the baking time, especially towards the end—about 40-50 minutes should do the trick! Another tip is to ensure all ingredients are at room temperature and properly measured.
Are these brownies safe for people with allergies?
Great question! These fudgy Biscoff brownies contain eggs, dairy, and gluten. If you have allergies or dietary restrictions, consider substitutions—like using a gluten-free flour blend or an egg replacer. Always check the labels on your Biscoff cookie spread to ensure it aligns with any dietary needs. For dog lovers, be sure to keep these treats away from your furry friends as chocolate is harmful to them!
