AITA For Eating (half) the cake my husband made?

So my husband likes to bake. He doesn’t do it a lot though because of “obligations” 🌚🌚.

He made a cake Friday and I really liked it, so I ate some of it. He didn’t like that I ate it, saying I ate too much even though about half was still left for him and our kids. I don’t know why he got so mad about it because he could just make another one. But now he’s been being a little baby about it because he swears up n down there’s nothing left.

AITA?
