Combine cake mix, eggs, and melted butter in a mixing bowl with a wooden spoon. Drop by the spoonful (or using a cookie scoop) onto a greased cookie sheet.
Bake 8-10 minutes at 350°. Allow to cool completely before frosting.
Place softened butter for frosting in a mixing bowl. Beat with an electric hand mixer till creamy.
Add powdered sugar 1/2 c. at a time to avoid a mess; add almond extract.
Add marshmallow fluff and mix well.
Frost cookies and carefully draw Baymax faces on each one with the frosting gel. Enjoy!
