Prepare muffin tins by lining with 18 cupcake liners. Preheat oven to 350 degrees.
In a large bowl, combine cake mix, butter and eggs. Put 2 Tablespoons of batter into each muffin cup.
Top batter with pie filling, 1 Tablespoon per muffin cup.
Bake 18-20 minutes. Remove from oven and allow to cool completely.
Whisk together powder sugar and lemon juice. Add a splash of milk, if necessary, to make it thin enough to drizzle. Drizzle glaze over cooled cakes. I removed cupcake liners before drizzling, but that's optional.
