I've baked a snowflake bundt cake, a dozen mini bundt cakes (cupcake size), ten mini zucchini loaves, and a gluten-free chocolate bundt cake so far. At the church I'll bake four dozen chocolate chip cookies and a big mess of Party Mix. I wonder if that's enough for 40 people.
My guess is a good number of them are on diets, so it's probably enough.
