How to Make Biscoff Blondies with Biscoff Ganache and Cookie Crumble Recipe

Step 1: Preparing Your Pan and Oven

Begin by preheating your oven to 350ºF, or 325ºF if your oven runs hot or uses convection or gas. Grease and line an 8×8-inch square pan with parchment paper, avoiding glass pans to get the best texture. This prep step is simple but crucial for even baking and easy blondie removal.

Step 2: Melting the Butter and White Chocolate

In a heatproof bowl, combine the unsalted butter, Biscoff butter, and chopped white chocolate. Melt them together carefully either in short bursts in the microwave or over a double boiler. Stir frequently until the mixture is smooth and velvety, perfectly melding those creamy, buttery notes that are the heart of your blondies.

Step 3: Adding the Sugar and Eggs

Stir in the granulated sugar to the melted mixture, whisking lightly. It might look separated—don’t worry, this is normal. Then, add the eggs one by one, whisking thoroughly after each addition. Follow by mixing in the extra egg yolk and vanilla extract, which tangibly enrich the batter’s flavor and texture.

Step 4: Incorporating the Dry Ingredients and Cookies

Gently fold in the flour and salt with a spatula, taking care not to overmix to keep your blondies tender. Next, fold in the chopped filled Biscoff cookies. These chunks are what bring delightful surprise crunch and that warm Biscoff character inside every square.

Step 5: Baking the Blondies

Pour the batter into your prepared pan, smoothing the top with a spatula for an even bake. Bake for 30-35 minutes until the edges are set and the center is done but still moist—you can test with a toothpick to ensure it doesn’t come out with wet batter. If the top browns too quickly, tent with foil and finish baking to perfection.

Step 6: Preparing the Biscoff Ganache

While the blondies cool, warm the heavy cream and Biscoff butter in a microwave or on the stove just until very hot but not boiling. Pour this over the chopped white chocolate, cover, and let it sit for a minute. Whisk until the ganache is silky smooth. If it’s too thick, add small amounts of warm cream until it reaches a spreadable consistency.

Step 7: Assembling the Final Touches

Spread the ganache evenly over the cooled blondies. Sprinkle the crumbled Biscoff cookies liberally on top to add a crunchy finish. Let the whole masterpiece set for at least 30 minutes before slicing and serving, to ensure clean cuts and perfect texture.

How to Serve Biscoff Blondies with Biscoff Ganache and Cookie Crumble Recipe

A square, thick cake sits on a round wooden board with a white marbled surface underneath covered partly by sheet music. The cake has two main layers: a dark brown base and a smooth, light brown caramel-like frosting layer that covers the top and drips slightly over the edges. The frosting is sprinkled with crumbled golden-brown biscuit bits evenly across the surface. Around the wooden board, there are whole round sandwich biscuits with a dark filling, a jar of caramel spread with a red lid, a white container with a wooden lid and spoon, and a white pitcher with a small red heart on it, all against a clean white marbled background.

Garnishes

A simple dusting of powdered sugar or a few extra Biscoff cookie crumbs can make these blondies look as irresistible as they taste. If you want to go all out, top each piece with a small dollop of whipped cream or a drizzle of caramel sauce for an elegant touch that complements the spiced flavors.

Side Dishes

Pair these blondies with a scoop of vanilla ice cream or a cup of rich, dark coffee to balance their sweetness. Fresh fruit like raspberries or sliced pears can also add a refreshing contrast to the sweet, buttery notes of the Biscoff blondies.

Creative Ways to Present

Consider serving these blondies as part of a dessert platter, cutting them into smaller squares and layering them with other spiced treats or chocolate bites. You can also serve them warm with ganache slightly melted, allowing guests to add their own toppings like crushed nuts, sea salt flakes, or even a splash of liqueur for an adult twist.

Make Ahead and Storage

Storing Leftovers

Keep your leftover Biscoff Blondies with Biscoff Ganache and Cookie Crumble Recipe in an airtight container at room temperature for up to 3 days, or refrigerate if your kitchen is on the warmer side. This helps maintain the ganache’s silky texture and the cookies’ crunch.

Freezing

If you want to save some for later, these blondies freeze wonderfully. Wrap individual pieces tightly in plastic wrap and place them in a freezer-safe container or bag for up to 2 months. Thaw overnight in the fridge and bring to room temperature before serving for the best flavor.

Reheating

To enjoy these blondies warm, pop them in the microwave for 10-15 seconds or briefly in a warm oven. This warms the ganache slightly, enhancing the gooey, rich texture without melting the cookie crumble topping.

FAQs

Can I use regular peanut butter instead of Biscoff butter?

While peanut butter offers a nice creamy texture, it won’t replicate the unique spiced caramel flavor of Biscoff butter. For the authentic taste that makes this recipe shine, stick to Biscoff butter.

What type of Biscoff cookies work best for the crumble?

Using the classic filled Biscoff cookies adds a great textural contrast with their crunchy, caramelized spice layers. Regular Biscoff biscuits can work too but won’t offer the same depth or melting quality.

Can I make this recipe vegan or dairy-free?

This recipe relies heavily on butter, white chocolate, and cream, so a vegan or dairy-free version would require substitutions like plant-based butters and non-dairy chocolate. It’s doable but may alter the final texture and flavor significantly.

How do I know when the blondies are fully baked?

The blondies are done when the edges look set and slightly golden, and the top appears firm. A toothpick inserted near the center should come out with moist crumbs but not wet batter.

Can I use dark chocolate instead of white chocolate?

Dark chocolate can be substituted, but it will change both the flavor and sweetness level. White chocolate lends a creamy sweetness that complements the Biscoff ideally, so dark chocolate will create a richer, more intense flavor profile.

Making the Biscoff Blondies with Biscoff Ganache and Cookie Crumble Recipe is such a joyful experience that leads to an unforgettable dessert everyone will rave about.
