Equipment Needed

• 9×13-inch baking pan

• Parchment paper or aluminum foil for lining

• Mixing bowls

• Electric mixer or hand whisk

• Spatula or wooden spoon

• Saucepan or microwave-safe bowl (for chocolate topping)

Step 1: Prepare the Baking Pan

1. Preheat the oven to 350°F (175°C).

2. Line a 9×13-inch baking pan with parchment paper or aluminum foil, leaving extra hanging edges for easy removal later.

3. Lightly grease the lining with butter or nonstick spray to prevent sticking.

Tip: Lining the pan ensures the squares lift out cleanly, making slicing much easier.

Step 2: Make the Buttery Crust

1. In a mixing bowl, cream together butter and sugar until smooth and light, about 2–3 minutes.

2. Mix in vanilla extract.

3. Gradually fold in flour and salt until dough forms.

4. Press the dough evenly into the prepared pan, making sure it reaches all corners.

5. Optional: prick the crust lightly with a fork to prevent puffing.

Tip: Use your fingers or the back of a spoon to press the dough firmly—this ensures a compact base that holds the dulce de leche well.

---

Step 3: Bake the Crust

1. Place the pan in the preheated oven and bake for 15–20 minutes, or until lightly golden around the edges.

2. Remove from oven and allow to cool slightly.

Tip: The crust should be firm but not browned excessively; slight golden edges are ideal for a buttery flavor.

---

Step 4: Add the Dulce de Leche Layer

1. Spread the dulce de leche evenly over the baked crust using a spatula.

2. If desired, sprinkle a pinch of sea salt for a salted caramel variation.

3. Smooth the top to ensure even coverage across the entire crust.

Tip: For a creamier texture, slightly warm the dulce de leche in the microwave for 15–20 seconds to make it easier to spread.

---

Step 5: Prepare the Chocolate Topping

1. Combine chocolate chips and cream in a small saucepan or microwave-safe bowl.

2. Heat gently, stirring frequently, until the chocolate melts and the mixture is smooth.

3. Optional: add 1 tsp butter for extra gloss and richness.

4. Pour the melted chocolate evenly over the dulce de leche layer.

5. Spread with a spatula or spoon to create a smooth, even top layer.

Tip: Work quickly before the chocolate cools to avoid streaks or uneven spreading.

---

Step 6: Chill and Set

1. Place the pan in the refrigerator for at least 2–3 hours to allow the layers to firm up.

2. For best results, chill overnight; this makes slicing cleaner and ensures each square holds its shape.

Tip: Avoid freezing immediately, as freezing can cause the chocolate to crack when cutting.

---

Step 7: Slice Into Squares

1. Lift the dessert out of the pan using the parchment paper overhang.

2. Place on a cutting board.

3. Use a sharp knife warmed under hot water and wiped dry to cut clean squares.

4. Wipe the knife between cuts to avoid dragging chocolate across the layers.

Tip: For bite-sized pieces, cut into 1.5–2 inch squares. For larger serving portions, 2–3 inch squares are ideal.

---

Step 8: Optional Garnishes

• Sprinkle chopped nuts over the chocolate layer before chilling.

• Dust with cocoa powder for extra visual appeal.

• Add a few sea salt flakes for a subtle crunch and contrast.

• For festive occasions, top with edible gold leaf or chocolate curls.

Step 9: Storage and Shelf Life

1. Store dulces de leche squares in an airtight container in the refrigerator for up to 5 days.

2. For longer storage, freeze individual squares separated by parchment paper for up to 2 months.

3. Thaw in the refrigerator before serving to maintain texture.

Tip: Allow refrigerated squares to sit at room temperature for 10–15 minutes before serving for softer, more decadent bites.

---

Step 10: Troubleshooting

• Chocolate streaks: Warm knife between cuts.

• Filling too runny: Chill longer or slightly thicken dulce de leche with a few drops of cream.

• Crust too crumbly: Press dough firmly before baking; ensure butter is fully softened when mixing.

• Layers separating: Make sure chocolate is poured over evenly; gentle pressing with spatula helps adhesion.

Step 11: Tips for Perfect Dulce de Leche Squares

1. Use quality ingredients: Real butter, high-quality chocolate, and authentic dulce de leche elevate flavor.

2. Level the layers: Smooth spread of filling and chocolate ensures clean, professional-looking squares.

3. Chill sufficiently: Proper chilling helps maintain the layered structure.

4. Work with a warm knife: Cuts are cleaner and more precise.

5. Experiment with textures: Nuts, coconut, or cookie crumbs can be added for variety.
