The Allure of Homemade Dulce de Leche Bars
Hello everyone! I’m Roxana, the self-taught baker, aspiring food photographer, and proud sugar addict behind Roxana’s Home Baking. Like Liz’s blog, my culinary space is dedicated to the art and joy of baking everything from scratch. There’s a common misconception that baking from scratch is overly complicated or prohibitively time-consuming. I’m here to challenge that notion and prove just how rewarding and simple it can be.
Home baking spans a wide spectrum, from the straightforward ease of a muffin recipe to the more intricate satisfaction of a yeast bread or a beautifully layered cake. My mission is to inspire you to cast aside those store-bought loaves and cake mixes, embrace the delightful mess of flour and sugar, and create something truly special in your own kitchen. Because, after all, some of the fondest memories are made amidst the aroma of fresh baking.
Most of the recipes you’ll discover on my blog, including these fantastic Dulce de Leche Bars, rely on fundamental techniques that anyone can master with a dash of patience and a sprinkle of passion. You don’t need to be a professional baker to achieve impressive results; you just need a willingness to try, and perhaps a craving for something sweet and comforting.

Crafting the Perfect Crumb Bar: An Easy-to-Follow Recipe
Today, I’ve brought an incredibly easy recipe for Dulce de Leche Bars. While reading through the directions might initially seem a little involved, I assure you, the process is remarkably straightforward. And the taste? Oh, the taste! It’s an explosion of rich, sweet caramel and buttery crumb, far exceeding the minimal effort required. These bars deliver maximum flavor with surprisingly little fuss.
The foundation of these delectable bars is a simple yet incredibly flavorful oatmeal cookie dough. We start with a harmonious blend of all-purpose flour, hearty rolled oats, rich butter, and sweet brown sugar. The brown sugar isn’t just for sweetness; it plays a crucial role in imparting that wonderful, chewy texture that makes these bars so addictive. Once you’ve gathered your ingredients, the dough comes together in less than two minutes in a food processor – truly a testament to its simplicity.
After preparing the dough, you’ll press the majority of it evenly into the bottom of a baking pan, creating a sturdy and delicious base. A quick bake in the oven sets this bottom layer perfectly. Then, the magic happens: a luscious layer of dulce de leche is generously spread over the warm crust. Finally, the reserved portion of crumbly dough is sprinkled on top, forming a delightful, golden-brown topping as it bakes. The aroma filling your kitchen will be absolutely divine!
Does that sound hard? Absolutely not! I told you it’s easy, and the results are consistently impressive. These Dulce de Leche Bars are not just a dessert; they are a celebration of simple ingredients transformed into something extraordinary. They’re perfect for potlucks, parties, or simply to enjoy with a cup of coffee for a sweet afternoon treat. The combination of the chewy oatmeal crust and the gooey caramel filling is simply irresistible, making them a crowd-pleaser every time.
Tips for Perfect Dulce de Leche Bars
Achieving bakery-quality Dulce de Leche Bars at home is within your reach with a few simple tips:
- Use Cold Butter: For the crumb base, ensure your butter is diced and cold. This helps create a tender, flaky crust rather than a tough one. The food processor quickly incorporates it without overworking.
- Don’t Overmix: When making the dough in the food processor, pulse just until the ingredients come together. Overmixing can develop the gluten in the flour too much, leading to a less tender bar.
- Warm the Dulce de Leche: Gently warming the dulce de leche before spreading makes it much easier to work with, ensuring an even, luscious layer across your base.
- Chill the Reserved Dough: Freezing or chilling the reserved dough makes it much easier to grate or crumble evenly over the caramel layer. This creates that perfect streusel-like topping.
- Cool Completely: Patience is key! Allow the bars to cool completely in the pan before attempting to cut them. This ensures they set properly, allowing for clean cuts and preventing a gooey, sticky mess. If you try to cut them too soon, the caramel will still be very liquid.
- Storage: Store these bars in an airtight container at room temperature for up3-4 days, or in the refrigerator for up to a week. They are delightful slightly chilled.
Variations to Explore
While these Dulce de Leche Bars are heavenly on their own, don’t hesitate to experiment with variations to suit your taste:
- Nutty Crunch: Add a half cup of chopped pecans or walnuts to the crumb topping for an extra layer of texture and flavor.
- Chocolate Drizzle: Once cooled, melt some dark or milk chocolate and drizzle it over the bars for an even more decadent touch.
- Spiced Oats: A pinch of cinnamon or nutmeg in the oatmeal crumb dough can add a warm, comforting spice note.
- Coconut Delight: Mix in a quarter cup of shredded coconut to the crumb mixture for a tropical twist.
These simple additions can transform your bars and offer a new experience each time you bake them. No matter how you serve them, these homemade Dulce de Leche Bars are sure to become a cherished recipe in your baking repertoire.

20 minutes

1 hour 20 minutes

Ingredients
Recipe courtesy of Roxana’s Home Baking
- 1 1/2 cups (180 grams) all-purpose flour
- 1 1/2 cups (135 grams) rolled oats
- 1 cup (200 grams) brown sugar
- Pinch of salt
- 1 cup (226 grams) diced cold butter
- 1 can (380 grams) dulce de leche, at room temperature
Instructions
- Prepare the Pan: Heat your oven to 350°F (175°C). Line an 11×7-inch baking pan with parchment paper, leaving an overhang on the sides for easy lifting. Set aside.
- Make the Dough: In a food processor, combine the all-purpose flour, rolled oats, brown sugar, salt, and diced cold butter. Pulse a few times until the mixture comes together into a cohesive dough ball.
- Reserve Dough for Topping: Remove about 1/2 cup of the cookie dough from the food processor. Shape this reserved portion into an oval disc, wrap it tightly in plastic wrap, and place it in the freezer while you prepare the base.
- Form the Base: Press the remaining dough evenly onto the bottom of the prepared baking pan. Ensure it forms a compact, uniform layer.
- First Bake: Bake the dough base for 20 minutes, or until lightly golden around the edges.
- Warm Dulce de Leche: While the base is baking, open the can of dulce de leche. Transfer the thick caramel sauce to a small saucepan and heat it gently over low heat on the stovetop, stirring constantly, until it becomes warm and easily spreadable. Do not boil.
- Add Dulce de Leche: Without turning off the oven, carefully remove the pan from the oven. Pour the warm dulce de leche evenly over the par-baked crust, spreading it right to the edges.
- Add Crumb Topping: Retrieve the frozen, reserved cookie dough. Using a coarse grater, grate the frozen dough directly over the dulce de leche layer, distributing the crumbs evenly.
- Final Bake: Return the pan to the oven and bake for an additional 30 minutes, or until the topping is golden brown and the dulce de leche filling is bubbly around the edges.
- Cool and Cut: Take the pan out of the oven and place it on a wire rack. Allow the bars to cool completely to room temperature before attempting to lift them out of the pan and cut them into squares. This is crucial for clean cuts. Enjoy!
