EASY cake mix pineapple upside down cupcakes in a muffin tin instead of cake is fun to cook with kids and costs $3.00 total for the whole recipe with ingredients from The Dollar Store.
Make yellow cake mix as directed (for deeper pineapple flavor use pineapple juice in place of water if that is needed in directions). Spray your muffin pan with non stick spray (I wouldn't use paper liners)
Melt butter and then whisk together with brown sugar. Spoon 1 tbsp into each muffin tin hole + 2-3 pieces of pineapple tidbits + 1 cherry in middle + pour batter on top of that (fill to 3/4 of the way full for each muffin hole).
Bake in preheated oven at 350 degrees for approx. 15 -18 min. or until top of cupcake springs back when touched gently in the center.
Cool tin on a cooling rack for 10 minutes before scooping out with a spoon or flipping pan over on to a large cutting board.
