Preheat oven to 350℉.
Line a muffin pan with cupcake liners.
Make cake mix according to directions.
Put aside about ⅓ of the batter in a bowl.
Add red food coloring.
Use 2 piping bags to fill liners about ¾ full. Alternate plain and red batter. Use more of the plain in each, so the red shows through more. (You can even just use a spoon to alternate each.)
Bake according to directions and allow to cool.
Use a large piping tip to core out the center of each cupcake.
Fill each with strawberry jam.
Frost and add a gummy candy to each cupcake.
Makes 12-16 cupcakes.
