FAQ

What do I do if my brownies are still undercooked after the suggested baking time?

If your brownies are too wobbly in the centre, return them to the oven for a few more minutes. Keep checking until a toothpick comes out with a few moist crumbs.

Can I use chunky Biscoff spread instead of the smooth one for swirling?

Absolutely, using chunky Biscoff spread can provide an extra crunchy element to your brownies and create a unique texture.

Why is it important to cool the brownies before cutting them?

Cooling allows the brownies to set and results in clean, neat slices. Cutting them too soon can lead to a messy appearance.

Pro Tips and Guidance

Use High-Quality Chocolate: Choose good-quality dark chocolate as it significantly influences the richness and depth of flavour in your brownies.

Properly Melt the Chocolate and Butter: When melting the chocolate and butter, do it gently over low heat or in short 10-second bursts in the microwave. Stir frequently to avoid overheating, which can cause the mixture to seize.

Sift the Dry Ingredients: Sifting the flour and cocoa powder together helps ensure they are well combined and prevents lumps in your batter.

Fold, Don’t Overmix: When incorporating the dry ingredients into the wet mixture, fold them gently. Overmixing can lead to tough brownies. Stop once the ingredients are just combined.

Don’t Overbake: Keep a close eye on your brownies, as overbaking can result in dry and crumbly brownies.

Cool Before Cutting: Allow the brownies to cool in the tin for about 30 minutes before cutting. This cooling period helps them set and makes slicing easier.

Warm Knife for Clean Slices: To achieve clean, neat slices, dip a sharp knife in hot water before cutting the brownies. Wipe the knife clean between each cut to maintain a polished appearance.

Storage

Storage:

These Swirled Lotus Biscoff Brownies are best when enjoyed fresh. Store any leftover brownies in an airtight container at room temperature for up to 2-3 days. Placing a sheet of parchment paper between the layers helps prevent them from sticking together.

Reheating:

To restore that warm, gooey texture, gently reheat individual brownie servings in the microwave for 10-15 seconds. Be cautious not to overheat, as it can cause the brownies to become dry.

Defrosting:

Since these brownies don’t contain ingredients prone to freezer burn, you can freeze them for longer storage. Place them in an airtight container or wrap them tightly in plastic wrap, then store in the freezer for up to 3 months. When you’re ready to enjoy them, allow the brownies to thaw at room temperature for a couple of hours or overnight in the fridge.
