Preheat oven to 400°F and grease an 8x8-inch baking pan.
In a medium saucepan, combine baked beans, brown sugar, mustard, Worcestershire sauce, and garlic powder. Heat over medium heat, stirring occasionally, until warmed through and keep warm on low.
In a mixing bowl, combine cornbread mix, creamed corn, egg, milk, and melted butter, stirring just until combined (don't overmix).
Pour cornbread batter into prepared pan and spread evenly.
Bake for 20-25 minutes until golden brown and a toothpick inserted in center comes out clean.
Serve warm cornbread squares alongside or topped with the hot baked beans, drizzled with honey if desired.
