#### Step 1: Prepare the Base (Optional)
– In a medium bowl, combine the graham cracker crumbs, melted butter, and powdered sugar. Mix until well combined.
– Press the mixture into the bottom of an 8×8-inch baking dish lined with parchment paper or greased with butter. Set aside.

#### Step 2: Make the Caramel Layer
– In a medium saucepan over medium heat, melt the butter. Stir in the brown sugar, sweetened condensed milk, heavy cream, and salt.
– Bring the mixture to a simmer while stirring constantly. Let it cook for about 4-5 minutes, or until it thickens slightly.
– Remove from heat and stir in the vanilla extract. Pour the caramel over the prepared base (if using) or directly into your baking dish. Let it cool and set for about 15-20 minutes.

#### Step 3: Make the Fudge Layer
– In a separate saucepan over low heat, melt the butter and sweetened condensed milk together, stirring occasionally.
– Once melted and smooth, add the chocolate chips. Stir constantly until the chocolate chips are completely melted and the mixture is smooth.
– Remove from heat and stir in the vanilla extract.

#### Step 4: Assemble the Fudge Squares
– Pour the fudge mixture over the set caramel layer. Use a spatula to spread it evenly over the top.
– Let the fudge cool at room temperature for a few hours, or refrigerate for about 2-3 hours until it sets and firms up.

#### Step 5: Cut and Serve
– Once the fudge is set, remove it from the pan using the parchment paper (if used) and cut into squares.
– Serve and enjoy your creamy caramel fudge squares!

These squares are a perfect treat for any occasion, with the rich combination of buttery caramel and smooth chocolate that’s sure to satisfy your sweet tooth. Enjoy!
