Preheat the oven to 400. Spray 24 muffin tin cups with non-stick cooking spray.
Prepare the cornbread batter by whisking together all the dry ingredients. Stir in the wet ingredients and let the batter sit for 10 minutes.
Drop a spoonful of batter into the muffin tin, then add a hot dog piece, then fill the muffin cup with more batter.
If you want to make mini muffins, fill the cup half full, then press the hot dog piece into the middle of the batter, leaving some of the hot dog showing on the top.
Bake in the preheated oven for 16 to 18minutes, or until cornbread is cooked through in the center.
To Freeze: Let cool completely before adding to plastic freezer baggie or container. Let thaw in the refrigerator and reheat in the microwave. If sending in a lunchbox, reheat them and drop them into a thermos container to keep them warm.
