One of my favorite cookies is shortbread. Every year during the holidays I serve mine with a citrus glaze and could honestly eat every last one of them. I have to hurry and bundle them up before they disappear. Today’s version has a chocolate-caramel topping that is just as addictive.
With the topping a cross between a pudding and frosting, these bars are wonderfully messy to eat and your littlest ones will definitely have a face covered with chocolate after eating them. It would make the cutest photographs!
The Artist is a total cookie hound. They are by far his favorite dessert, snack and if he could get away with it, breakfast, lunch, and dinner! While Italian classics are his passion, nearly any cookie will do in a pinch, especially if chocolate is involved. When he heard what I making today, he gave up lunch just so he had enough room to enjoy these dessert bars.
One of the tricks to getting these bars out of their baking pan is to create a parchment “sling.” I have sheets of parchment paper so I folded mine to fit my pan and tucked it into the pan. It worked perfectly without any cutting involved. You bake the shortbread in the pan then spread the chocolate topping over the cooled cookie crust. Put the whole thing in the refrigerator and use the parchment paper “handles” to lift the bars out of the pan when you are ready to cut them.
If you don’t use the right knife these may shatter on you. They are very delicate and rather crumbly. You want a long, very sharp knife, preferably with a granton edge. This knife is sometimes called a hollow edge carving knife or slicer. The granton edge is the one that looks like it has dimples on the side. It creates an extremely sharp edge that will cut cleanly through nearly anything. I use mine all the time and it has more than paid for itself over the years.
If you wanted two different flavors, you could double the recipe and bake the shortbread in two different square baking pans. Then when you caramelize the sweetened condensed milk, transfer half to another bowl and proceed with the recipe as directed. Use the reserved half to cover one of the shortbread crusts, creating a caramel version. And of course, you can use this recipe as the base for lemon bars!
When I found out I was gluten-intolerant I was worried that I would never be able to make my favorite shortbread again, but I substituted white rice flour for the regular all-purpose in this recipe and you can’t tell the difference. I am thrilled!
Make these cookies for a special occasion, the holidays, or just because it is Chocolate Monday! Have a wonderful week!!
Jane’s Tips and Hints:
Remember if you are baking for someone who has celiac disease (you’ll have to ask about their level of sensitivity), you cannot use anything that has touched regular flour when you are baking. For some people, cross-contamination is enough to send them to the hospital. Wooden cutting boards, rolling pins, cooking spoons etc. can all retain gluten even after scrubbing. It is safer to buy new equipment if you will be baking for them often, or ask them to bring a dessert that everyone can enjoy together.
- Shortbread Crust
- 3/4 cup cornstarch
- 1 cup all-purpose flour or white rice flour (GF option)
- 1/2 tsp salt
- 1 cup unsalted butter, at room temperature
- 5-1/2 tbsp powdered sugar
- Chocolate Caramel Layer
- 1 (14 oz) can sweetened condensed milk (NOT evaporated milk)
- 1 cup heavy cream
- 4 large egg yolks
- 5 oz bittersweet chocolate (at least 65%), finely chopped, or high quality chocolate chips such as Guittard
- Make the Shortbread Crust: Set an oven rack in the center of the oven and preheat it to 375°F.
- Butter a 9-inch square baking pan (about 1 to 1-1/2 inches deep). Cut a piece of parchment paper wide enough to cover the bottom and long enough to come up both sides and hang over the edges. This will help you get the bars out of the baking pan. Butter the parchment paper; set aside.
- In a bowl, combine the cornstarch, flour and salt. Whisk until blended.
- In the bowl of your standing mixer, cream the butter until smooth. Add the sugar and blend until sugar is completely incorporated. Add the flour mixture and mix until smooth.
- Spread the soft dough in the prepared pan, using an off-set spatula to make sure it is even and the top is smooth, pressing into the corners. Prick the entire surface with a fork. Transfer to the hot oven and bake until golden, about 20 to 25 minutes. The edges will be darker than the center. Remove from the oven and place on a wire rack to cool.
- Once the shortbread is cool, drape the top with a piece of parchment. Leave at room temperature while you make the Chocolate Caramel.
- Make the Chocolate Caramel: Set a rack in the center of the oven and preheat to 400°F.
- Pour the sweetened condensed milk into a shallow ovenproof dish. A glass pie plate is perfect because you can see when the milk changes color more easily. Cover dish tightly with foil and place in a large baking dish or roasting pan. Place the roasting pan on the oven rack and fill the outer pan with hot water until it reaches 3/4 of the way up the side of the covered dish creating a water bath. VERY slowly push the rack back in the oven, being careful not to splash the hot water on yourself.
- Bake for 1 to 1-1/2 hours or until golden brown. If the water is boiling too hard, reduce heat to 375°F. Check regularly to make sure the water level is high enough, refilling with hot water as needed. After an hour, use tongs to lift back part the foil covering, being VERY careful not to burn yourself with the steam to check the color. Continue baking as needed.
- Slip a stiff heatproof or wooden spatula under one side of the pie plate, raising it slightly out of the water. Using potholders, remove pie plate from the water bath and set on a heatproof trivet on the counter. Whisk caramel until smooth. Turn off the oven and leave hot water in the oven until it is cool enough to easily discard without burning yourself.
- Place the heavy cream and the caramelized milk in a saucepan and bring to a simmer over medium heat, whisking until smooth. Pour half of this mixture into a heatproof measuring cup (I like Pyrex).
- In the bowl of your stand mixer or a heatproof bowl, whisk the egg yolks until smooth. Very slowly add half the hot cream mixture, whisking constantly. This tempers the eggs, gently warming them slowly so they don’t scramble. Transfer the egg/cream mixture back into the saucepan and cook over medium heat, stirring constantly, until it registers 170°F on an instant-read thermometer (just below a simmer), about 5 minutes.
- Remove from the heat and add the chocolate. Whisk until all the chocolate is melted and the mixture is smooth.
- Assemble the Bars: Pour the chocolate/cream mixture over the top of the shortbread crust, jiggling it until it covers the entire surface, corner to corner. Chill in the refrigerator, uncovered, until set and fully chilled, about 2 hours.
- To Serve: Run a knife around the edges to loosen and then using the parchment paper “handles,” move it to a cutting board. Use a long knife heated under hot running water, to cut a thin slice off each side, wiping the knife clean with hot water between each cut. Then cut the square in half, drawing the knife through without lifting it up. Rinse and wipe again, then cut the opposite direction so you have even quarters. Cut each quarter into thirds to create 12 bars. Using the parchment as handles again, lift the bars back into the baking dish. Chill until ready to serve.
- Store in an airtight container in the refrigerator. Best eaten the day they are made.
- Yield: 12 bars
- If you have two ovens you can make the caramelized milk and bake the shortbread at the same time.

I was wondering if I could use Dulce de Leche (already caramelized sweetened condensed milk)? The recipe sounds great, and this would speed up the prep time considerably.

Hi Melodie – you absolutely can use dulce de leche. I don’t have a good source here, but if you do, by all means, use it instead. It will make these much faster to assemble, and therefore you can eat them more quickly, LOL!!

Those are simply beautiful! That topping….oh man.

Thanks Cathy – lip smacking good 😉 !!
