Detailed Directions and Instructions
Step 1: Preheat the Oven
Preheat the oven to 350°F. Prepare an 8×8-inch baking pan by lining it with parchment paper, ensuring some overhang for easy removal later.
Step 2: Cream Butter and Sugar
In a large bowl, combine the softened butter and sugar. Use a mixer or wooden spoon to cream them together until the mixture is smooth and well incorporated.
Step 3: Add Flavorings
Incorporate the vanilla extract and salt into the butter and sugar mixture. Mix thoroughly until fully combined.
Step 4: Mix in Flour
Gradually add the all-purpose flour to the mixture. Stir until a crumbly dough forms, ensuring the flour is evenly distributed throughout.
Step 5: Press the Dough
Transfer the dough to the prepared baking pan. Press it down evenly to create a smooth base across the bottom of the pan.
Step 6: Bake the Base
Place the pan in the preheated oven and bake for approximately 20 minutes, or until the edges of the base are lightly golden.
Step 7: Cool the Base
Remove the pan from the oven and let the base cool for about 5 minutes. This cooling stage is crucial before adding the dulce de leche.
Step 8: Spread Dulce de Leche
Once the base has cooled slightly, evenly spread the dulce de leche over the surface. If the dulce de leche appears too thick, microwave it for 20–30 seconds to soften for easier spreading.
Step 9: Add Toppings (Optional)
If desired, sprinkle your choice of sea salt flakes, mini chocolate chips, or crushed pecans over the dulce de leche layer to enhance flavor and texture.
Step 10: Cool Completely
Allow the entire dessert to cool completely at room temperature. Then, refrigerate it for 1–2 hours to set properly.
Step 11: Serve the Bars
Once the dessert has firmed up, lift it out of the pan using the parchment paper overhang. Cut the dessert into squares for serving.
Notes
Note 1: Butter Temperature
Ensure that the butter is truly softened, not melted, for optimal mixing and texture in the final product.
Note 2: Dulce de Leche Texture
If you do not have dulce de leche on hand, you can make it at home by simmering sweetened condensed milk, but be sure to let it cool before spreading.
Note 3: Storage
Store the finished bars in an airtight container in the refrigerator to maintain freshness, consuming them within a week for the best flavor.
Note 4: Serving Suggestions
These bars can be served as a treat on their own or paired with a scoop of vanilla ice cream for an extra indulgent dessert.

Cook Techniques
Creaming
Creaming is the process of mixing softened butter with sugar until the mixture is light and fluffy. This technique is essential for creating a light texture in baked goods. Ensure the butter is at room temperature for optimal results.
Mixing
Mixing involves combining ingredients until well incorporated. Use a gentle folding technique when adding flour to maintain the dough’s structure and avoid overworking it, which can lead to dense bars.
Pressing
When pressing the dough into the baking pan, use your fingers or the back of a measuring cup to ensure an even layer. This helps form a solid base for the bars.
Baking
Baking at 350°F allows for even cooking without burning the edges. Keep an eye on the bars; they should be lightly golden around the edges when done.
Cooling
Cooling the base slightly before adding the dulce de leche is crucial. This prevents melting and ensures a clean layer when slicing the bars.
Refrigerating
Refrigerating the completed bars helps them set properly. Allow 1-2 hours for chilling to ensure they hold their shape when cut.
