Preheat the oven to 375 F. Line a 9x13 pan with nonstick foil.
Combine butter and sugar.
Beat eggs, caramel, and syrup into the sugar mix.
Add flour, baking soda, and salt, and mix until smooth.
Spread into the lined pan and bake for 20-30 minutes, until a toothpick inserted into the center comes out clean.
Cool completely and cut into squares.
