In a mixing bowl, combine the dry cake mix, melted butter, and egg.
Stir until a thick, sticky dough forms.
Press into Pan:
Transfer the dough to the prepared baking dish and press it evenly into the bottom using your hands or a spatula.
Bake:
Bake for 20–25 minutes, or until the edges are golden brown and the center is set but still slightly soft.
Cool & Slice:
Let the bars cool in the pan for at least 10–15 minutes before slicing into squares.
Serve & Enjoy!
These bars are delicious warm or at room temperature. Serve as-is or with a scoop of ice cream for extra indulgence!
Optional Add-Ins:
Sprinkle chocolate chips, butterscotch chips, or nuts on top before baking.
Drizzle with caramel or chocolate sauce after baking.
Enjoy your Ooey Gooey Bars!
