For the Base
• Unsalted Butter – Provides richness and moisture; ensure it is softened for easy mixing.

Step‑by‑Step Instructions for Dulce de Leche Revel Bars
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C), ensuring it’s hot enough for perfect baking. While the oven warms, line a 9×9” baking pan with aluminum foil, leaving some overhang for easy removal later. Grease the foil well with butter or cooking spray to prevent sticking, which will make slice-and-serve a breeze once your Dulce de Leche Revel Bars are baked.
Step 2: Cream the Butter and Sugar
In a large mixing bowl, use a hand mixer or stand mixer to cream the softened unsalted butter and brown sugar together until the mixture is light and fluffy. This should take about 2-3 minutes. The fluffy texture indicates that air is incorporated, which helps make your bars light and chewy. Scrape down the sides of the bowl to ensure even mixing.
Step 3: Add Wet Ingredients
Next, beat in one egg and a splash of pure vanilla extract into the creamed butter and sugar mixture. Mix until it’s completely combined and creamy, incorporating the egg’s rich texture throughout. Then, sprinkle in the baking soda and salt, and beat for an additional moment. This step is crucial for flavor balance and ensuring your Dulce de Leche Revel Bars rise just properly.
Step 4: Combine Dry Ingredients
Gradually add the all-purpose flour into the wet mixture, mixing just until it starts to come together. Be careful not to overmix, as this can lead to dense bars. Once the flour is incorporated, gently fold in the quick cooking oats, using a spatula to maintain the mixture’s lightness. The dough should be thick and slightly sticky, ready for layering.
Step 5: Form the Base
Using your clean hands or a spatula, press half of the oat mixture evenly into the bottom of your prepared baking pan. Aim for an even layer that covers the bottom completely, which will create a lovely base for your Dulce de Leche filling. Ensure the mixture is packed firmly, as this will help it hold together after baking.
Step 6: Layer the Dulce de Leche
In a microwave-safe bowl, warm the dulce de leche in the microwave for about 30 seconds or until it’s smooth and pourable. Carefully drizzle the melted dulce de leche over the oat base, leaving roughly a ¼-inch border along the edges. This luscious caramel layer will be the star of your Dulce de Leche Revel Bars, adding that irresistible gooeyness.
Step 7: Add the Top Layer
Take the remaining oat mixture and crumble it over the dulce de leche filling. Spread it evenly, ensuring that the caramel is mostly covered. Gently pat it down with your fingers to create a cohesive top layer. This will help create a delightful texture, providing that perfect balance of crunchy oat topping against the rich filling.
Step 8: Bake to Perfection
Place the pan in your preheated oven and bake for 23-28 minutes. Keep an eye on the bars; they’re done when the top is golden brown and the center has a slight jiggle. This visual cue indicates that the bars are perfectly cooked, maintaining that desired chewy texture while the flavors meld beautifully.
Step 9: Cool and Slice
Once baked, remove the pan from the oven and let it cool completely in the pan on a wire rack. This will take about 30 minutes to an hour. Cooling is essential for achieving clean, beautiful slices. Once cool, lift the bars out using the foil overhang, slice into squares, and get ready to indulge in your homemade Dulce de Leche Revel Bars!

Make Ahead Options
These Dulce de Leche Revel Bars are a fantastic choice for meal prep, allowing you to savor homemade goodness even on the busiest days! You can prepare the oat mixture up to 3 days in advance; simply combine all dry ingredients, and refrigerate in an airtight container until you’re ready to bake. Additionally, the baked and cooled bars can be stored at room temperature for up to 3 days, or frozen in individual portions for up to 3 months. To maintain their delicious texture, cool the bars completely before slicing and wrap them tightly. When you’re ready to enjoy, simply thaw and serve, and you’ll find they’re just as delightful as when freshly baked!

Dulce de Leche Revel Bars Recipe FAQs
What type of oats should I use for Dulce de Leche Revel Bars?
For the best texture, I recommend using quick cooking oats. They provide the perfect chewiness and blend beautifully into the dough. If you only have rolled oats on hand, you can substitute those, but the bars may have a slightly different texture – still delicious, but a bit heartier!
How should I store leftover Dulce de Leche Revel Bars?
Store leftover bars in an airtight container at room temperature for up to 3 days. If you want them to last a bit longer, you can refrigerate them for up to a week. Just make sure they’re well-covered to keep out any fridge odors.
Can I freeze Dulce de Leche Revel Bars?
Absolutely! To freeze, wrap individual slices tightly in plastic wrap or foil, then place them in a freezer-friendly container. They can be frozen for up to 3 months. When you’re ready to enjoy them, simply thaw in the fridge overnight and warm in the microwave for about 10-15 seconds for that comforting gooeyness.
What should I do if my bars turn out too dry?
If your bars turn out dry, it may be due to overbaking or using too much flour. Make sure to watch the baking time closely and pull them out when the top is golden brown but still slightly jiggly in the center. If you find they are a bit dry, try adding a drizzle of extra dulce de leche on top or serve with a scoop of ice cream to bring back moisture.
Can I make Dulce de Leche Revel Bars vegan or gluten-free?
Definitely! You can make them vegan by substituting the egg with a flax egg (1 tablespoon of ground flaxseed mixed with 2.5 tablespoons of water, let sit for 5 minutes). For a gluten-free version, simply use a gluten-free flour blend instead of all-purpose flour. Both adjustments won’t compromise the deliciousness of your Dulce de Leche Revel Bars.
How do I know if my ingredients are fresh enough for baking?
For optimal results, ensure your baking powder and baking soda are fresh; they should produce bubbles when mixed with liquid. Check your flour for any off smells, and if you’re using oats, make sure there are no dark spots or a stale scent. Using fresh ingredients will enhance the flavor and texture of your bars!
