Make It Your Way

I love sharing this fudge just as it is, but don’t hesitate to tweak things to fit your taste or occasion. This recipe’s straightforward base is perfect for your own creative spin.

Variation: Once, I swapped half the white chocolate for milk chocolate to create a creamier, less sweet profile—perfect if you prefer something a tad more mellow.
Dietary Swap: Using dairy-free white chocolate and condensed coconut milk lets you make a vegan-friendly version that’s just as yummy.
Seasonal Touch: Adding a sprinkle of cinnamon or nutmeg on top takes this fudge from everyday treat to holiday showstopper.

Step-by-Step: How I Make Biscoff Fudge Squares Recipe

Step 1: Prep Your Pan for Easy Release

I always line my 8-inch square baking pan with parchment paper before starting. It’s a small step but makes lifting out the fudge squares a breeze — no sticky fingers or broken bits!

Step 2: Melt the Ingredients Gently

Combine white baking chocolate, sweetened condensed milk, Biscoff spread, and salt in a large microwave-safe bowl. I microwave in 30-second bursts, stirring in between to keep everything silky. Watch closely — you want everything melted smoothly without overheating.

Step 3: Fold in Cookies and Layer

Stir half the chopped Biscoff cookies right into the warm fudge mixture — it adds that lovely crunch inside. Pour the mixture into your prepared pan, smooth the top, then sprinkle the rest of the cookie pieces on top. Press down gently so they stick.

Step 4: Chill Until Firm

Pop the fudge in the fridge and let it set for at least 2 hours. It’s hard to wait, but trust me, patience means perfect creamy, sliceable squares!

Top Tip

After making this fudge a bunch of times, I’ve picked up a few tricks to get it just right every time.

Gentle Melting: Avoid rushing the melting process. Low and slow (or short microwave intervals) keeps the chocolate smooth and prevents seizing.
Cookie Texture: Don’t over-chop the Biscoff cookies—they should be chunky enough to add texture, not just dust.
Pressing the Topping: Press the cookies on top lightly so they don’t sink but stick well—otherwise, they’ll fall off when you slice.
Using a Double Boiler: If you’re wary of microwaves, I love the double boiler method for better heat control.

How to Serve Biscoff Fudge Squares Recipe

Garnishes

I usually keep it simple with a drizzle of extra melted Biscoff spread on top — it adds a glossy, rich finish and ups the flavor punch. Sometimes I sprinkle a tiny pinch of crushed sea salt for contrast, which is fantastic too.

Side Dishes

These fudge squares are perfect alongside a steaming cup of coffee or chai tea — the spices in the drink and fudge complement each other beautifully. They also make a delightful finish to a casual brunch or holiday dessert platter.

Creative Ways to Present

For parties, I like arranging the fudge squares on a tiered dessert stand or wrapping individual pieces in wax paper tied with twine for cute giveaways. Adding fresh edible flowers or cinnamon sticks as accents really makes them pop visually.

Make Ahead and Storage

Storing Leftovers

The key to keeping these fudge squares fresh is an airtight container in the fridge. They stay perfectly soft yet firm, and I usually enjoy them for up to a week — if they last that long!

Freezing

I’ve frozen these fudge squares several times without sacrificing texture or flavor. My trick is to freeze them first laid out individually on a baking sheet, then transfer to a sealed container or Ziploc bag. That way they don’t stick together, and you can grab just the amount you want later.

Reheating

When you’re ready to enjoy frozen fudge, let the squares thaw in the fridge for a few hours or simply sit at room temperature for about 20 minutes. I find microwaving gently for a few seconds helps soften them if desired, but be careful not to melt them completely.

Frequently Asked Questions:

Can I make these Biscoff fudge squares without white chocolate?

You can, but it will change the flavor and texture. White chocolate provides a creamy sweetness that balances the spiced Biscoff spread. If you prefer, substitute with milk chocolate—just expect a slightly richer and less sweet fudge.

What if I don’t have Biscoff spread?

No worries! Speculoos spread is a great substitute as it has similar flavors. Alternatively, you can try making your own by blending ground Biscoff cookies with a little oil, although it won’t be quite as smooth.

How thick will the fudge be if I use a 9-inch pan instead of an 8-inch one?

Using a 9-inch pan will result in thinner fudge squares as the same amount of mixture spreads out more. If you prefer thicker squares, stick with the 8-inch pan or consider increasing the batch size slightly.

Can I make this fudge recipe without salt?

Yes! The salt just helps enhance the sweetness and depth of flavor, but leaving it out won’t ruin your fudge. It’ll still taste delicious, especially with the natural caramel notes of Biscoff.
