Ingredients You'll Need

A group of bowls and containers with baking ingredients are arranged on a white marbled surface. In the front row, there are two white bowls, one holding three raw eggs with bright yellow yolks, and the other filled with white sugar. Next to them is a small bowl with two thick slabs of butter in pale yellow. Behind these, a white bowl contains finely chopped white chocolate pieces with a creamy texture. To the right and back, there is a white bowl full of crumbled brown cookies or biscuits with a rough texture. Next to it, a bottle of vanilla extract with a dark brown liquid and a red jar of Biscoff spread are visible. A speckled white bowl filled with a white powdery ingredient, likely flour, stands beside a white container with a wooden lid, a small spoon inside, and a wooden cutting board at the back. All items are set neatly with warm, natural light shining from the right side, creating soft shadows. Photo taken with an iphone --ar 4:5 --v 7

Each ingredient in this recipe plays a crucial role, coming together to create the perfect balance of texture and flavor. From the richness of the butters to the crunch of the chopped Biscoff cookies, every element enhances the sweet, spiced essence of this dessert.

White chocolate (chopped, 1¼ cup + ¾ cup): Adds creamy sweetness and melt-in-your-mouth smoothness to both the blondie base and ganache.
Biscoff butter (¾ cup + 2 tbsp): Infuses that iconic spiced caramel flavor throughout the blondies and the ganache topping.
Unsalted butter (½ cup): Provides a rich fat base that keeps the blondies tender and moist.
White granulated sugar (¾ cup): Sweetens the blondies, balancing the buttery and cookie flavors perfectly.
Large eggs (2) + 1 large yolk: Bind everything together and give the blondies their structure and tender crumb.
Vanilla extract (2 tsp): Enhances all the other flavors with a subtle, aromatic depth.
All-purpose flour (2 cups): The backbone that gives the blondies their chewy yet cakey texture.
Salt (¼ tsp): Just a pinch to brighten and balance sweetness.
Filled Biscoff cookies (10, chopped small): They create irresistible bursts of cinnamon-spiced crunch throughout the blondies.
Heavy cream (⅓ cup): Blends into the ganache providing a creamy, luscious finish.
Crumbled Biscoff cookies (5-6): A perfect garnish that adds texture and extra cookie goodness on top.

How to Make Biscoff Blondies with Biscoff Ganache Recipe

Step 1: Prepare your pan and oven

First things first, preheat your oven to 350ºF. If your oven tends to run hot, try 325ºF instead to prevent over-browning. Grease and line an 8×8” square pan with parchment paper—this will make sure your blondies come out cleanly without sticking. Avoid glass pans here, as they might cook unevenly.

Step 2: Melt the butter and white chocolate

In a large bowl, combine the unsalted butter, Biscoff butter, and chopped white chocolate. Melt them together carefully, either in short 15-30 second bursts in the microwave or over a double boiler, stirring often. You want a smooth, shiny mixture—that blend is the foundation for your rich blondies.

Step 3: Add sugar and eggs

Stir the granulated sugar into the melted mixture. It might look a little separated at this stage, but don’t worry. Add the eggs one at a time, whisking after each addition until fully incorporated. Then whisk in the extra egg yolk along with the vanilla extract to deepen the flavor.

Step 4: Fold in dry ingredients and Biscoff cookies

Next, gently fold in the all-purpose flour and salt with a spatula just until combined. Too much stirring here can make the blondies dense, so be gentle. Then fold in the chopped filled Biscoff cookies—the little pockets of cookie surprise make every bite exciting.

Step 5: Bake the blondies

Pour your batter into the prepared pan and smooth out the top with a spatula. Bake for 30-35 minutes until the edges are set and the top looks just firm. To check doneness, a toothpick inserted should come out mostly clean with just a few moist crumbs—not wet batter. If you notice the blondies browning too fast but still underbaked inside, tent them with foil and keep baking.

Step 6: Cool before ganache

Once baked, let your blondies cool completely in the pan. This pause is important—the ganache will spread best on a cool surface and prevent it from melting into the blondies.

Step 7: Prepare the Biscoff Ganache

Warm the heavy cream and Biscoff butter together until hot (around 175ºF) but not boiling. Pour this mixture over the chopped white chocolate and cover for a minute. Then whisk gently until everything is melted and silky smooth. If the ganache feels too thick, add a bit more warm cream, teaspoon by teaspoon, to loosen the texture for easy spreading.

Step 8: Spread and set the ganache

Pour the ganache over your cooled blondies and spread it evenly. Sprinkle the top with the crumbled Biscoff cookies for extra texture and cookie appeal. Let the whole thing set for about 30 minutes, then slice into squares and get ready to swoon.

How to Serve Biscoff Blondies with Biscoff Ganache Recipe

The image shows a square piece of layered dessert placed on a wooden board. The dessert has two thick layers: the bottom layer is a dense, textured cake with visible small chunks inside, colored light brown with darker specks, and the top layer is a smooth, creamy caramel-colored frosting. The frosting is topped with small crunchy crumbles scattered evenly across the surface. Several more pieces of the same dessert, all cut into squares, are aligned closely in the background. There are two round golden brown cookies with a patterned surface placed near the wooden board on top of a white marbled texture with sheet music underneath.

Garnishes

A sprinkle of extra crumbled Biscoff cookies on top adds a delightful crunchy contrast to the creamy ganache. For extra flair, add a light dusting of powdered sugar or a drizzle of melted white chocolate to elevate presentation and add even more sweetness.

Side Dishes

These blondies pair perfectly with a scoop of vanilla ice cream or a dollop of whipped cream. For a slightly tangy balance, fresh berries like raspberries or strawberries can complement the spiced caramel flavors beautifully.

Creative Ways to Present

Try cutting the blondies into mini bite-sized squares and serving on a decorative platter for parties. Or sandwich them with creamy frosting or ice cream between two blondie squares for a decadent sandwich treat that everyone will adore.

Make Ahead and Storage

Storing Leftovers

Store any leftover blondies in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week. This keeps them fresh and preserves the ganache’s creamy texture.

Freezing

If you want to keep your blondies longer, freeze them in a sealed container or freezer bag for up to 3 months. Thaw overnight in the fridge and then bring to room temperature before serving for the best flavor.

Reheating

Warm leftover blondies gently in the microwave for 10-15 seconds to slightly soften the ganache and warm the filling without melting it completely. This gives a soft, fresh-from-the-oven feel with every bite.

FAQs

Can I use regular peanut butter instead of Biscoff butter?

While peanut butter brings its own deliciousness, it doesn't replicate the distinct caramelized, cinnamon flavor of Biscoff butter. If you want to stick to the signature taste of this recipe, it’s best to use Biscoff butter.

Do I have to use white chocolate for the ganache?

Yes, using white chocolate is key here because it complements the caramel spice of Biscoff butter perfectly. Dark or milk chocolate will change the flavor profile significantly.

Why shouldn’t I use a glass pan for baking blondies?

Glass pans tend to heat unevenly and can cause the edges of your blondies to cook faster than the center, potentially leading to uneven baking. Stick with metal pans for the best result.

Can I make these gluten-free?

You can swap the all-purpose flour for a gluten-free blend that measures like regular flour. Just make sure your mix has xanthan gum for structure. The texture might be slightly different but still delicious!

How do I know when the blondies are perfectly baked?

Look for blondies that are set at the edges and top with a firm surface. A toothpick inserted in the center should come out with a few moist crumbs, but not wet batter. Overbaking makes them dry, so keep an eye on them!

This Biscoff Blondies with Biscoff Ganache Recipe is truly a game-changer for blondie lovers and Biscoff fanatics alike.
