baking comes from bake + the suffix -ing; bake is from Old English bacan ('to bake'), from Proto-Germanic *bakaną. Morphologically, the word is transparent as a compound: its parts remain visible in the modern spelling, while the older history of those parts supplies the deeper ancestry. In modern use, the noun sense is "the act of cooking by dry oven heat; intensely hot", which keeps the etymology connected to the word's present dictionary value rather than treating it as a merely historical label. The wider word family includes related English forms such as bake, baked, baker, showing how the same base continues to support neighboring English vocabulary. The principal historical forms in the chain include Old English bacan, Proto-Germanic *bakaną, which anchor the explanation in named linguistic material.
