Biscoff Millionaire’s Shortbread: A Cozy Twist on a Classic Treat

When the air turns crisp and the days grow shorter, there’s nothing quite like the comfort of homemade treats filling the kitchen with sweet, buttery aromas. Biscoff Millionaire’s Shortbread is one of those indulgences that instantly wraps you in warmth, blending layers of crumbly shortbread, rich caramel, and silky Biscoff spread. This dessert is more than just a sweet bite; it’s a little slice of nostalgia.

I first discovered Biscoff Millionaire’s Shortbread during a holiday gathering where a friend brought a tray, gleaming with golden caramel and topped with that unmistakable spiced cookie flavor. Each bite tasted like a hug: the buttery shortbread melting in your mouth, the soft caramel layer stretching ever so slightly, and the Biscoff topping delivering a cozy, cinnamon-kissed finish. Since then, it’s become a personal favorite to bake for family gatherings, potlucks, and especially during the holiday season when you want to treat your loved ones to something extra special.

Originating as a twist on the beloved millionaire’s shortbread—a treat that’s been around for decades—this Biscoff version elevates the classic by adding the caramelized flavor of speculoos cookies. It’s a dessert that beautifully balances nostalgia with a modern, crave-worthy twist.

How to Make Biscoff Millionaire’s Shortbread

Making Biscoff Millionaire’s Shortbread is like building edible architecture, layering flavor upon flavor until you have the perfect dessert bar.

Step-by-Step Instructions

Step 1: Prepare the Shortbread Base
Preheat your oven to 350°F (175°C). Line an 8×8-inch square baking pan with parchment paper. Cream the softened butter and sugar together until light and fluffy. Gently mix in the flour and salt until combined. Press this mixture evenly into the prepared pan. Bake for 20–25 minutes, or until lightly golden at the edges. Let it cool completely.

Step 2: Make the Caramel Layer
In a saucepan over medium heat, combine butter, brown sugar, golden syrup, and sweetened condensed milk. Stir constantly for 10–15 minutes, until the mixture thickens and turns a rich golden color. Pour the caramel over the cooled shortbread base and spread evenly. Chill in the refrigerator until set, about 1–2 hours.

Step 3: Add the Biscoff Topping
Gently warm the Biscoff spread until it’s pourable (you can microwave it in short bursts). Pour over the chilled caramel layer and smooth it out. Drizzle melted white chocolate on top for a decorative finish. Chill again until firm before slicing into squares.

Helpful Tips

• Use a sharp knife warmed under hot water to cut clean slices.
• For the best texture, store the bars in the fridge but bring them to room temperature before serving.
• Line your pan well with parchment to make lifting the bars out easy and mess-free.
• Be patient when making the caramel; stirring constantly ensures it won’t burn.
