From Start to Finish: 7-Layer Dulce De Leche Oatmeal Chocolate Chip Bars.

Step 1: Prepare Your Pan
Start by preheating your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving some overhang for easy removal later.
Step 2: Combine Dry Ingredients
In a large mixing bowl, whisk together the old-fashioned oatmeal, all-purpose flour, light brown sugar, baking soda, salt, and cinnamon (if using). This will be the base for your bars.
Step 3: Mix Wet Ingredients
In another bowl, combine the canola oil, eggs, and vanilla extract. Whisk until well combined and slightly frothy.
Step 4: Combine Wet and Dry Mixtures
Pour the wet ingredients into the dry ingredients and mix until just combined. The batter will be thick and hearty.
Step 5: Layer the Base
Spread half of the oatmeal mixture evenly into the prepared baking pan. Use a spatula to press it down firmly to create a solid base.
Step 6: Add the Dulce de Leche
Drizzle the warmed dulce de leche over the base layer, spreading it out so it covers the oats evenly.
Step 7: Add the Chocolate Chips & Coconut
Sprinkle the flaked coconut and ½ cup semi-sweet chocolate chips over the dulce de leche layer.
Step 8: Add the Remaining Oatmeal Mixture
Take the remaining oatmeal mixture and crumble it over the top of the coconut and chocolate layer. Press down gently to ensure it sticks.
Step 9: Drizzle with Sweetened Condensed Milk
Drizzle the sweetened condensed milk over the top of the crumbled layer, ensuring it spreads out evenly.
Step 10: Add Roasted Cashews
Sprinkle the roasted cashews over the top for extra crunch and flavor.
Step 11: Bake
Place the pan in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and the edges are slightly crispy.
Step 12: Finish with Dark Chocolate
Once baked, remove the bars from the oven and immediately drizzle the melted dark chocolate over the top. Allow it to cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
Step 13: Slice and Serve
Once cooled, use the parchment overhang to lift the bars out of the pan. Slice into squares or rectangles and enjoy your delicious creation!
Year-Round Variations

- Switch up the nuts: Try pecans or almonds instead of cashews for a different flavor profile.
- Add dried fruits: Incorporate raisins or dried cranberries for a chewy texture.
- Use different chocolate: Experiment with white chocolate chips for a sweeter twist.
- Seasonal spices: Add nutmeg or pumpkin spice during fall for a seasonal touch.
Avoid These Mistakes
To ensure your 7-Layer Dulce De Leche Oatmeal Chocolate Chip Bars turn out perfectly, avoid these common pitfalls:
- Not pressing the layers down firmly: This helps create a cohesive bar that holds together.

- Baking at the wrong temperature: Make sure your oven is preheated to 350°F (175°C) for even baking.
- Overbaking: Keep an eye on the bars to prevent them from drying out.
