Stir the non-dairy milk and vinegar together in a measuring cup. Set aside to curdle which will be your vegan buttermilk. Melt the butter.
Measure dry ingredients into a medium size bowl and stir together.
Make a well in the center of the dry ingredients. Add the buttermilk, melted butter, and maple syrup. Stir until the batter comes together.
OPTIONAL ADD INS: Now is the time to fold any add ins ie. corn kernels, green onions, and jalapeños into the batter.
Remove the HOT pan from the oven, add 1 tablespoon of butter and the halved garlic clove swirl to coat the bottom and sides of the skillet. Remove the garlic pieces.
Swirl the cornbread batter evenly into the hot pan.
Garnish the top with thin slices of jalapeños, a handful of green onion slices, and coarse black pepper if desired.
Reduce heat to 375ºF then bake for 20 - 25 minutes until the top is golden and the a toothpick comes out clean when tested in the center.
Let cool for at least 15 minutes before slicing and serving.
