How to Make Millionaire Shortbread Cookies Step by Step

Prepare the Pan: Line a 9×9-inch baking dish with parchment paper, leaving an overhang for easy removal later.
Make the Shortbread: Cream butter, sugar, and salt until light and fluffy. Mix in the vanilla and egg yolk, then slowly incorporate the flour until just combined. Press evenly into your pan and bake at 350°F for about 22 minutes, or until golden at the edges.
Cook the Caramel: In a saucepan, melt butter with brown sugar, salt, sweetened condensed milk, vanilla, and syrup. Stir constantly over medium heat until the caramel thickens and turns a deep golden color (about 5–6 minutes or 225°F).
Layer the Caramel: Pour the hot caramel over the cooled shortbread and smooth it evenly. Chill for 10 minutes until set.
Make the Chocolate Ganache: Melt chocolate and cream together in a heatproof bowl over simmering water or in short microwave bursts, stirring until silky smooth.
Assemble and Chill: Spread the ganache over the caramel layer, sprinkle with sea salt flakes, and refrigerate until firm.
Cut and Serve: Once set, lift the Millionaire Shortbread Cookies from the pan and slice into neat squares or bars using a sharp knife.

Frequently Asked Questions About Millionaire Shortbread Cookies

1. Can I make Millionaire Shortbread Cookies without a thermometer?
Yes, while a thermometer helps ensure precision, you can make the caramel layer by observing texture and color. The caramel should bubble steadily, thicken noticeably, and pull slightly from the sides of the pan when ready — usually after about 5–6 minutes on medium heat.

2. How do I keep the layers from mixing together?
Cooling is key. After pouring the caramel over the shortbread, chill it for at least 10 minutes before adding the chocolate ganache. This ensures clean, distinct layers and prevents the chocolate from sinking into the caramel.

3. Can I add toppings or flavor twists to this recipe?
Definitely! Crushed nuts, toffee bits, or even a swirl of white chocolate can add both flavor and texture. For a seasonal touch, sprinkle crushed peppermint candies on top or add a pinch of sea salt for that perfect sweet-salty contrast.

4. What’s the best way to store and serve Millionaire Shortbread Cookies?
Keep them in an airtight container at room temperature for up to five days, or refrigerate for a firmer texture. If freezing, wrap each piece tightly in plastic wrap and thaw at room temperature before serving to maintain that perfect caramel consistency.
