Now I'm not saying a boy can't enjoy a pink cake covered with donuts and sprinkles, but if we're gonna follow hetero-normative social gender constructs, it's pretty clear who this cake is for.
Next time you are hosting a quilting bee (and I know it's soon! Don't lie!) you can present snacks on little appropriate stands made out of thread spools. Themed presentation of snacks is one of the little things that make get-togethers extra special.
