How to Make Dulce de Leche Bars
-
Prepare the Oven & Pan: Preheat your oven to 350°F (175°C). Line a 9″x13″ baking pan with parchment paper to prevent sticking and make for easy removal.
-
Mix the Crust: In a large bowl, combine all-purpose flour, oats, light brown sugar, and salt. Cut in the softened unsalted butter until the mixture resembles coarse crumbs. Remember to reserve 1/4 of this mixture for the topping!
-
Form the Base: Firmly press the remaining crumb mixture into the bottom of the prepared pan. Pre-bake this crust for about 10 minutes—it should start to lightly brown.
-
Heat the Filling: In a saucepan over low heat, warm the dulce de leche until it becomes spreadable, taking around 3-4 minutes. Keep stirring to ensure it doesn’t scorch!
-
Assemble: Spread the warm dulce de leche evenly over the pre-baked crust. Sprinkle toffee bits on top, then add the reserved crumb mixture to finish the layering.
-
Bake: Place the assembled bars in the oven and bake for 25-30 minutes, until the top is golden brown. Your kitchen will smell heavenly!
-
Cool Down: Let the bars cool in the pan for 15 minutes. After that, run a knife around the edges and let them cool completely before slicing into delicious squares.
Optional: Serve slightly warm for an extra gooey treat!

On the day you plan to serve, heat the dulce de leche until spreadable, assemble with toffee bits and crumb topping, and bake as directed. This way, you’ll enjoy delicious, freshly baked bars without the last-minute rush, retaining all their gooey, rich flavor!

Dulce de Leche Bars Recipe FAQs
What type of oats should I use for the crust?
You can use either quick-cooking oats or old-fashioned oats in this recipe. Both options add lovely texture and chewiness to the bars. If you’re feeling adventurous, you can experiment with other types of oats, but keep in mind that the texture may vary a bit from what the recipe suggests.
How should I store leftover dulce de leche bars?
To keep your dulce de leche bars fresh, store them in an airtight container at room temperature for up to 3 days. If you’d like them to last longer, you can refrigerate them for up to 5 days. Just remember to warm them slightly in the microwave before enjoying to bring back that gooey goodness!
Can I freeze dulce de leche bars, and how?
Absolutely! For longer storage, wrap the bars individually in plastic wrap and place them in a freezer-safe container. They will stay delicious for up to 2 months. When you’re ready to enjoy, simply thaw them overnight in the fridge or at room temperature for a few hours.
How do I prevent over-baking and ensure a chewy texture?
To avoid over-baking your dulce de leche bars, keep a close eye on them as they bake. Start checking for doneness around the 25-minute mark. You’re looking for a golden brown top, and the center should be set but still soft. Remember, these bars will continue to cook a little as they cool, so it’s better to under-bake slightly than risk them becoming dry!
Are there any dietary considerations for dulce de leche bars?
Yes! This recipe contains dairy from the unsalted butter and dulce de leche. If you’re looking for a dairy-free option, you can substitute the butter with coconut oil and use a dairy-free caramel sauce. Always check labels for any specific allergies, especially if you’re serving to friends or family.
How do I know if my dulce de leche is ready to spread?
Warming the dulce de leche until it’s spreadable is key! Heat it slowly in a saucepan over low heat, stirring regularly, until it becomes a smooth, creamy consistency—usually around 3-4 minutes. If it’s still thick, give it a little more time on the heat and keep stirring to avoid scorching.
