Ingredient Notes
Please check the recipe card below for a detailed, printable ingredient list.
COOKIES – Biscoff cookies form your base layer with their special brown-sugar taste. One 9-ounce sleeve is exactly what you need. The warm spices in these cookies make both the caramel and chocolate taste even better. Regular speculoos cookies work too.
BUTTER – Use unsalted butter so you control how salty your bars taste. Room temperature butter for the caramel mixes smoothly without lumps. The melted butter holds your cookie crumbs together perfectly without making them soggy.
CONDENSED MILK – Sweetened condensed milk gives you that perfect chewy caramel that millionaire shortbread is famous for. American cans hold 14 ounces total, but you only need 10 ounces. Keep the extra for your morning coffee.
CHOCOLATE – Semi-sweet chocolate balances the sweet layers underneath just right. Chop it into small, even pieces so it melts smoothly. Want a grown-up version? Use dark chocolate instead.
COOKIE SPREAD – Biscoff cookie spread pumps up the cookie flavor in your caramel and chocolate. Its creamy texture melts right in without any lumps. Look for it by the peanut butter at your store.
SUGAR – Light brown sugar gives your caramel a deeper, richer taste than white sugar would. Press it down tight when you measure for the right amount. Dark brown sugar works but makes everything taste stronger.

Serving Suggestions
COFFEE PAIRING – Serve squares with espresso or cappuccino. The bitter coffee balances the sweetness and brings out the Biscoff spices.
ICE CREAM – Put a square next to vanilla ice cream. The cold-warm combo and different textures make each bite amazing.
GIFT BOX – Wrap single squares in clear plastic for bake sales or gift boxes. These travel well and look like they came from a bakery.
AFTERNOON TEA – Cut into smaller pieces for tea parties. The pretty layers and just-right sweetness work perfectly for fancy events.
Recipe Success Tips
CLEAN CUTTING – Run your knife under hot water and dry it between cuts. This stops the chocolate from cracking and keeps your layers looking perfect. Expert Tip – A thin, sharp knife works better than a thick one.
CARAMEL CONSISTENCY – Watch your caramel closely during the 5-6 minute cooking time. You want it thick enough to coat a spoon but still pourable. Cook it too little and it won’t set right.
CHOCOLATE MELTING – Expert Tip – Microwave at 50% power to avoid burning. Full power makes hot spots that ruin the smooth finish. Going slow gives you shiny, bakery-style results.
PARCHMENT OVERHANG – Leave at least 2 inches of parchment hanging over two sides. This makes handles for lifting the whole block out without messing up your layers.
Commonly Asked Questions
Can I Use Graham Crackers Instead Of Biscoff Cookies?
Graham crackers work but taste different. You’ll miss the warm spices that make these bars special. Add a teaspoon of cinnamon to graham cracker crumbs to help.
Why Is My Caramel Layer Too Soft?
You didn’t cook the caramel long enough. Cook the full 5-6 minutes until it gets thicker and a bit darker. It should stick to your whisk when you lift it up.
What Size Pan Can I Use Instead Of 8×8?
A 9×9 pan makes thinner bars that feed more people. Double everything for a 9×13 pan. Thinner bars need less time in the fridge to set.
How Do I Fix Cracked Chocolate?
Chocolate cracks when it gets too cold too fast. Let bars sit out 10 minutes before cutting. Keep them at the same temperature to stop future cracks.
Can I Add Nuts To The Millionaire Shortbread?
Chopped almonds or hazelnuts taste great sprinkled on the caramel before you add chocolate. Toast them first for better flavor. Keep pieces small so your bars still slice cleanly.

Millionaire Shortbread with Biscoff
Ingredients
Biscoff Cookie Base
- 1 9-ounce sleeve Biscoff cookies
- ½ cup butter unsalted, melted
Caramel Layer
- ½ cup butter unsalted, room temperature
- ½ cup light brown sugar
- 10 ounces sweetened condensed milk
- 2 tablespoons Biscoff cookie spread
- ½ teaspoon sea salt
Chocolate Biscoff Topping
- 8 ounce semi-sweet chocolate finely chopped
- ¼ cup Biscoff cookie spread
Instructions
- Line an 8×8-inch pan with parchment paper, leaving extra overhang on two sides to create handles for lifting the bars out later.
- Blend the cookies in a food processor until they form fine crumbs. Transfer to a mixing bowl and stir in the melted butter until the mixture resembles damp sand. Press the mixture firmly into the bottom of the pan using damp fingers. Refrigerate while preparing the caramel.
- In a medium saucepan, melt the butter over medium heat until small bubbles appear around the edges. Add the brown sugar and whisk until it starts to boil and the sugar fully dissolves, about 2 minutes.
- Whisk in the sweetened condensed milk and continue whisking over medium heat for 5 to 6 minutes, until the caramel thickens and turns slightly darker. Remove from heat and stir in the cookie spread and sea salt.
- Pour the caramel over the chilled crust and gently shake the pan to level the surface. Return to the refrigerator and chill for 15 minutes.
- Combine the chopped chocolate and cookie spread in a microwave-safe bowl. Microwave at 50% power for 1 minute, then stir. Continue microwaving in 30-second increments at 50% power, stirring each time, until smooth. This may take up to 5 minutes depending on the microwave.
- Spoon the melted chocolate over the caramel layer and use the back of a spoon to smooth it out. Sprinkle sea salt over the top and refrigerate until fully set before slicing.
