There are some desserts that look like you spent half the afternoon baking, when really, the oven did nearly all the work. These Oven-Baked 5-Ingredient Dulce de Leche Shortbread Bars are exactly that kind of treat—rich, buttery, gooey, chocolatey, and wonderfully simple.
Start with whole, unbroken shortbread cookies arranged snugly in a metal baking pan. Add a little melted butter, pour over creamy dulce de leche, scatter chocolate chips across the top, and finish everything with a delicate sprinkle of flaky sea salt. After a short bake, the chocolate becomes soft enough to spread into a smooth layer while the caramel melts down into the buttery cookie base.
The result is an irresistible combination of crisp shortbread, creamy caramel, silky chocolate, and salty-sweet flavor in every bite. They are perfect for afternoon coffee, holiday cookie trays, church suppers, potlucks, or those evenings when your husband asks what is for dessert and you want something that looks impressive without making a production out of it.

Ingredients
24 whole shortbread cookies
These form the buttery foundation of the bars. Keeping the cookies whole and unbroken makes assembly especially easy and gives each finished square a sturdy, crisp base.
1 can dulce de leche, about 13.4 ounces
This is the star of the recipe. Dulce de leche provides the thick, creamy caramel layer that melts into the shortbread and gives the bars their signature rich flavor.
1 cup semisweet chocolate chips
The chocolate creates the decadent topping. Semisweet chocolate works particularly well because its slight bitterness balances the sweetness of the caramel.
1/2 teaspoon flaky sea salt
A little flaky salt goes a long way. It adds a delicate savory contrast that makes the caramel and chocolate flavors taste even richer.
2 tablespoons unsalted butter, melted
The melted butter adds extra richness and helps the shortbread develop a beautifully buttery texture as the bars bake.
How to Make Dulce de Leche Shortbread Bars
1. Prepare the pan
Preheat the oven to 350°F. Lightly grease an oven-safe metal sheet pan or an 8×8-inch metal baking pan.
For especially easy removal, line the pan with parchment paper, leaving some overhang along the sides.
2. Arrange the shortbread
Place the whole shortbread cookies in a single, snug layer across the bottom of the pan.
Fit them closely together, but do not break them to force them into place. The cookies create the foundation for the entire dessert.
3. Add the melted butter
Lightly brush or drizzle the melted unsalted butter over the tops of the cookies.
You do not need to soak them. A light coating is enough to add richness and help the cookies bake into a deliciously buttery base.
4. Add the dulce de leche
Pour the dulce de leche evenly over the cookies.
Using the back of a spoon or a small offset spatula, gently spread it toward the edges until the cookies are covered with an even layer.
Work gently so you do not disturb the cookie arrangement underneath.
5. Add the chocolate chips
Scatter the semisweet chocolate chips evenly over the caramel layer.
Try to distribute them from edge to edge so every future square gets plenty of chocolate.
6. Bake
Place the pan in the preheated oven and bake for approximately 12 to 15 minutes.
The chocolate should be softened, and the dulce de leche should be warm and bubbly around the edges.
Keep an eye on the pan toward the end of baking. You want the chocolate softened enough to spread, not scorched.
7. Spread the chocolate
Remove the pan from the oven.
While the chocolate is still warm, use the back of a spoon or a small offset spatula to gently spread it into an even, thin layer across the top.
Immediately sprinkle the flaky sea salt over the warm chocolate.
8. Cool and chill
Allow the bars to cool completely in the pan.
For cleaner, more defined slices, transfer the pan to the refrigerator and chill for approximately 30 to 45 minutes.
Once firm, cut into 16 small squares.
Pro Tips for Perfect Bars
Use a metal pan. A metal baking pan heats efficiently and helps the shortbread develop crisp edges while warming the dulce de leche evenly.
Don’t overbake. The goal is to soften the chocolate and warm the caramel. Too much oven time can make the chocolate dry and the cookie base overly hard.
Spread the chocolate while warm. The chocolate chips will be soft immediately after baking, making them much easier to turn into a smooth topping.
Chill before cutting. These bars are rich and gooey when warm. Refrigerating them first makes slicing significantly easier.
Use a sharp knife. For neat squares, use a sharp knife and wipe the blade clean between cuts.
Don’t go too heavy on the salt. Flaky sea salt is powerful, so a light sprinkle is enough to create that delicious salty-sweet contrast.
Easy Variations
Dulce de Leche Pecan Bars
Add about 1/2 cup finely chopped toasted pecans over the dulce de leche before baking. The nuts bring a wonderful crunch and an old-fashioned dessert flavor.
Dark Chocolate Caramel Bars
Replace the semisweet chocolate chips with dark chocolate chips for a deeper, less-sweet chocolate flavor.
Milk Chocolate Shortbread Bars
For an extra-sweet version, use milk chocolate chips. This variation is especially appealing if you are serving children or anyone who loves classic caramel-and-chocolate combinations.
Holiday Shortbread Bars
Add a very light dusting of festive sprinkles immediately after spreading the chocolate. The combination of caramel, chocolate, and shortbread makes these especially attractive on holiday dessert trays.
How to Serve
These dulce de leche shortbread bars are rich enough to stand on their own, but they are especially good alongside something warm or refreshing.
Serve them with:
– Hot coffee
– Black tea
– Cold milk
– Vanilla ice cream
– Whipped cream
– Fresh strawberries
– Sliced apples
– Toasted pecans
For a dessert platter, cut the bars into smaller bite-sized pieces and arrange them alongside other cookies and candies. Their combination of buttery shortbread, creamy caramel, chocolate, and sea salt makes them an easy centerpiece for a casual gathering.
How to Store
Store completely cooled bars in an airtight container.
Keep them refrigerated if your kitchen is warm or if you prefer a firmer texture. Allow chilled bars to sit at room temperature for several minutes before serving so the caramel and chocolate soften slightly.
They are also an excellent make-ahead dessert, since chilling actually makes them easier to cut and serve.
Frequently Asked Questions
Can I use a different cookie instead of shortbread?
Yes. Choose a sturdy buttery cookie that can support the caramel and chocolate layers. Avoid very thin, delicate, or heavily filled cookies because they may not hold up as well.
Can I use homemade dulce de leche?
Absolutely. Homemade dulce de leche can be used as long as it has a thick, spreadable consistency similar to canned dulce de leche.
Why should I chill the bars before cutting?
The caramel and chocolate layers firm up as they cool. Chilling gives you cleaner, more attractive squares and makes the rich bars easier to handle.
Can I make these ahead of time?
Yes. These bars are well suited to making ahead. Prepare them, cool them completely, chill until firm, and store them in an airtight container until serving.
