Can you bake? Make munkkis (NB. they are not donuts!) and/or tippaleipäs. I bet you can find recipes online, at least in Finnish, but if you can speak some it shouldn't be a problem.
I am going to make munkkis, although we don't celebrate vappu here in the USA. My husband loves homemade Finnish munkkis. He even said "actually, don't make them, because I will eat them all in one go".
