Step‑by‑Step Instructions for Biscoff Brownies
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (180°C). While the oven is warming up, line an 8-inch square pan with parchment paper, allowing some overhang for easy lifting later. This simple lining technique will ensure that your gooey Biscoff brownies release effortlessly after baking.
Step 2: Melt the Chocolate and Butter
In a heatproof bowl, combine the butter and chocolate, placing it over a pot of simmering water to create a double boiler. Stir continuously until melted and smooth, about 5-7 minutes. If using a microwave, heat in 30-second intervals, stirring in between. Allow the mixture to cool slightly before moving to the next step, ensuring the chocolate stays glossy.
Step 3: Whisk the Wet Ingredients
In a large mixing bowl, whisk together eggs, granulated sugar, and vanilla extract until light in color and slightly fluffy, about 2-3 minutes. This process incorporates air into the batter, helping achieve a delightful texture in your Biscoff brownies.
Step 4: Combine the Mixtures
Gently stir the cooled melted chocolate mixture into the egg mixture using a rubber spatula. Ensure everything is well combined without overmixing. The glossy chocolate should blend seamlessly with the wet ingredients, creating a rich, decadent base for your batter.
Step 5: Fold in the Dry Ingredients
Sift in the all-purpose flour, cocoa powder, and salt. Carefully fold these dry ingredients into the wet mix until just combined—this creates the fudgy texture you’re looking for. Be cautious not to overmix; small lumps are perfectly fine. Finally, fold in the crushed Biscoff cookies for added flavor and crunch.
Step 6: Prepare for Baking
Pour the brownie batter into the prepared pan, using a spatula to level the top. For an extra treat, dollop spoonfuls of cookie butter on top, then gently swirl it into the batter with a knife to create beautiful marbled patterns. For added crunch, sprinkle additional crushed Biscoff cookies over the top if desired.
Step 7: Bake to Perfection
Place your pan in the preheated oven and bake for 30-35 minutes. Keep an eye on it; the edges should be set with a slightly soft center. You can check for doneness by inserting a toothpick; it should come out with a few moist crumbs for that perfect gooey brownie texture.
Step 8: Cool Before Serving
Once baked, allow the brownies to cool in the pan on a wire rack. For cleaner cuts, refrigerate for about 1 hour after cooling. This step will help the Biscoff brownies firm up a bit, making them easier to slice and serve, showing off those delicious cookie butter swirls.
