Equipment & Tools
You will need the following equipment to successfully prepare these bars:
- Mixing bowls – For combining the ingredients.
- Whisk or electric mixer – To blend the butter and sugar smoothly.
- Spatula – For folding in the ingredients and spreading the mixture in the pan.
- Baking pan (9×13 inches) – To bake the bars to perfection.

Dulce de Leche Revel Bars in Steps
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that the bars bake evenly and become perfectly golden.
Step 2: Prepare the Baking Pan
Line a 9×13 inch baking pan with parchment paper, leaving some overhang on the sides. This will make it easier to lift the bars out later.
Step 3: Cream the Butter and Brown Sugar
In a large mixing bowl, combine the softened unsalted butter and packed brown sugar. Use a whisk or electric mixer to cream them together until light and fluffy.
Step 4: Add the Egg and Vanilla
Add the large egg and vanilla extract to the creamed mixture. Mix until well combined, ensuring everything is evenly incorporated.
Step 5: Combine Dry Ingredients
In another bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually add this dry mixture to the wet ingredients, stirring until just combined.
Step 6: Fold in the Oats
Gently fold in the quick-cooking oats until they are evenly distributed throughout the batter.
Step 7: Layer the Batter
Spread half of the oat mixture into the prepared baking pan, pressing it down evenly. This will form the bottom layer of the bars.
Step 8: Add the Dulce de Leche
Spoon the dulce de leche over the bottom layer of the bars. Use a spatula to spread it evenly, ensuring that it covers the entire layer.
Step 9: Top with Remaining Oat Mixture
Take the remaining oat mixture and sprinkle it over the layer of dulce de leche. Gently press it down to create a cohesive top layer.
Step 10: Bake
Place the baking pan in the preheated oven and bake for about 25-30 minutes, or until the top is golden brown and set.
Step 11: Cool and Cut
Once baked, remove the pan from the oven and let it cool completely in the pan. Once cool, use the parchment overhang to lift the bars out and cut them into squares.
Fit It to Your Goals
If you’re looking to customize your Dulce de Leche Revel Bars, consider the following options:
- Nut Add-ins – Fold in some chopped nuts like walnuts or pecans for added crunch.
- Chocolate Chips – Mix in semi-sweet or dark chocolate chips for a chocolatey twist.
- Fruit – Add dried fruits like cranberries or raisins for a fruity flavor.
- Vegan Option – Substitute the butter with a plant-based butter and the egg with a flax egg (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water).
Easy-to-Miss Gotchas
Here are a few things to keep in mind while making your Dulce de Leche Revel Bars:
- Make sure your butter is softened, not melted, to achieve the desired texture.
- Don’t overmix the batter after adding the flour; you want to keep the bars tender.
- Allow the bars to cool completely before cutting to ensure clean edges.
- If the dulce de leche is too thick, warm it slightly in the microwave for easier spreading.
Keep It Fresh: Storage Guide
To keep your Dulce de Leche Revel Bars fresh, store them in an airtight container at room temperature for up to 5 days. If you want to keep them longer, you can refrigerate them for up to a week. For longer storage, consider freezing them. Wrap individual bars in plastic wrap and place them in a freezer-safe container. They can be frozen for up to 3 months. Simply thaw at room temperature before enjoying!
Reader Q&A
Can I use rolled oats instead of quick-cooking oats?
Yes, you can use rolled oats, but the texture may be slightly different. Quick-cooking oats blend more seamlessly into the batter, while rolled oats will provide a chewier texture.
What can I substitute for dulce de leche?
If you don’t have dulce de leche, you can use caramel sauce or make your own by simmering sweetened condensed milk. Just ensure it’s thick and spreadable.
Can I make these bars gluten-free?
Absolutely! You can substitute the all-purpose flour with a 1:1 gluten-free flour blend. Make sure your oats are certified gluten-free if necessary.
How do I know when the bars are done baking?
The bars are done when the top is golden brown and set. A toothpick inserted into the center should come out clean or with a few moist crumbs.
