An oven is a multi-purpose piece of electronic equipment that has evolved throughout the years and has become what us 2000s rich people call expensive fire in a box.

Most people that aren't completely fucking stupid, which probably excludes Alex, use it to bake or cook things.

Alex doesn't own a functioning oven, thus she grills her cookies in a pan and smokes those chocolate muffins like no one else ( for obvious fucking reasons, would you eat smoked batter).

Alex's baked goods such as cookies can optionally be selected as weapons, I mean who never wanted to break some asshole's window.
