millionaire bars
Directions:
Preheat oven to 350F and line a 9x9 inch baking dish with parchment paper. Make sure your parchment paper is hanging over all the edges. Do not skip this step! Using parchment paper makes it significantly easier to take the millionaire shortbread out of the dish to cut. Trust me.
Cream the butter then add the sugar, salt and beat until light and fluffy. Add the vanilla and egg yolk then mix until combined. Add the flour in a few batches and mix until just combined.
Transfer to your prepared pan and press into an even layer then bake at 350F for about 22 minutes or until the edges are golden.
While the shortbread bakes make the caramel. Combine the butter, brown sugar, salt, vanilla, sweetened condensed milk and corn syrup.
Place over medium heat and whisk until melted and combined. Continue whisking over the heat while the caramel bubbles and dakens to a richer color. You will see it start to thicken and pull away from the edge- around 5-6 minutes. When this is happening, the caramel is ready.
Pour onto the shortbread base, smooth to the edges creating a flat layer. Chill for about 10 minutes so the caramel sets. It’s very important the caramel is set before you make the chocolate layer.
In a double boiler or microwave, melt the chocolate. If using a microwave do it in 20 second sessions mixing between each time. If the chocolate starts to harden and get a sandy texture, you have cooked it too long. If you’re using a double broiler, constantly stir the chocolate til smooth and then immediately pour over the caramel creating a smooth flat top layer. Chill before cutting into pieces.
Optional to sprinkle flaky salt on top. If you prefer nuts, this would be the time to sprinkle those on top.
