For the Brownie Batter

Biscoff Butter – Adds a creamy, spiced flavor that pairs perfectly with chocolate. Note: Can substitute with cookie butter if needed.
Melted Butter – Provides richness and moisture to the batter. Prep Note: Ensure it is melted but not hot when mixing with chocolate.
Granulated Sugar – Sweetens the brownies while helping to achieve a fudgy texture.
Eggs – Acts as a binder and provides structure. Note: Use large eggs for best results.
All-Purpose Flour – Creates the brownie structure; do not overmix after adding. Substitution: Gluten-free all-purpose flour may be used for a gluten-free version.
Baking Soda – A leavening agent that aids in rising but is used sparingly to maintain a dense texture.
Vanilla Extract – Enhances the flavor; pure vanilla extract is preferred for depth.
Salt – Balances sweetness and intensifies the flavors. Note: Sea salt on top enhances the final product.
Chopped Chocolate – Adds rich chocolate flavor and texture. Substitution: Chocolate chips can replace chopped chocolate.

How to Make Decadent Biscoff Brownies

Preheat the oven to 350°F (175°C) and line a 9x9 inch square baking pan with parchment paper. This ensures easy removal and clean-up after baking.
Melt the chopped chocolate with the melted butter in a microwave, using intervals of 30 seconds. Stir until the mixture is smooth and velvety, creating a rich base for your brownies.
Combine sugar, eggs, and vanilla extract into the chocolate mixture. Stir until the mixture becomes glossy, signifying a well-blended batter full of flavor.
Sift in the all-purpose flour, baking soda, and salt. Mix until just combined, being careful not to overmix to maintain that fudgy texture everyone loves.
Pour the batter into the prepared baking pan, spreading it evenly. Drop spoonfuls of Biscoff butter on top and gently swirl with a toothpick to create a marbled effect, adding beauty to your brownies.
Bake for 30 minutes or until a toothpick inserted into the center comes out with a few moist crumbs, which means they’re perfectly done.
Cool the brownies completely in the pan. Once cool, lift them out using the parchment paper and slice into squares. This cooling step helps achieve the ideal texture and prevents crumbling.

Optional: Dust with powdered sugar before serving for an extra touch of sweetness.

Decadent Biscoff Brownies Recipe FAQs

What should I look for when selecting Biscoff butter?
When choosing Biscoff butter, look for a creamy texture without any dark spots or separation. It should have a pleasant spiced aroma and color. Ensure that it’s not too old; the shelf life is usually about 12 months from the production date. If you can only find cookie butter instead, that's perfectly fine as a substitute!

How should I store the brownies, and how long do they last?
Store your Decadent Biscoff Brownies in an airtight container at room temperature for about 4 days. If you want them to last longer, you can refrigerate them for up to 1 week. Be sure to wrap them well to prevent them from drying out.

Can I freeze these brownies? If so, how?
Absolutely! To freeze your brownies, first, let them cool completely after baking. Then slice them into individual squares, wrap each piece tightly in plastic wrap, and place them in a freezer-safe bag or container. They will keep well for up to 3 months. To enjoy, simply thaw them at room temperature for a few hours or microwave them for 10-15 seconds for a fresh-baked taste!

What do I do if my brownies turn out too cake-like?
If your brownies come out too cake-like, there are a few possible reasons: you might have overmixed the batter after adding the flour, or baked them for too long. For a fudgy texture, ensure you mix until just combined and always check for moist crumbs with a toothpick rather than a clean one, signaling they’re done baking.

Are these brownies suitable for my gluten-sensitive friends?
Yes! You can easily make these Decadent Biscoff Brownies gluten-free by substituting the all-purpose flour with a gluten-free all-purpose blend. Just ensure that all other ingredients, especially baking soda and chocolate, are gluten-free as well.

Can I use other types of chocolate for these brownies?
Certainly! While I recommend using high-quality dark chocolate (60% cocoa or higher) for depth of flavor, you can use semi-sweet chocolate or even milk chocolate for a sweeter treat. If you prefer chocolate chips, they will work just as well; just keep in mind that the melting process will differ from using chopped chocolate.
