no, it's not feminine. Baking cakes is for everyone. well not everyone, but you get my drift.
I myself love cooking and experiment with baking cakes, it's fun to add little things here and there. But I always overdid it.
One time I was baking chocolate chip cookies and I put so much choco chips and almond powder it was ugly, but taste yummy nonetheless. I think.
Remember, unlike cooking where you can always add salt, pepper or sugar later to balance taste, baking is a lot more precise. You have to measure carefully and stick with the recipe.
what cake are you gonna you bake?
