Cool the small cakes in pan for 10 minutes, then remove and set on cooling rack to cool completely. Cut the two pound cakes into French fries, using a crinkle cutter or a knife. Drizzle half of the melted butter on an aluminum foil lined baking sheet, set the cake fries on the foil. Drizzle the remaining butter over top. Bake at 325°F for 15-20 minutes, flipping after 10 minutes, until deep golden brown.
