Heat the oven to 350 degrees, and line two muffin tins with cupcake liners.
Beat together the eggs, applesauce, vanilla, eggs, Greek yogurt, baking powder, salt, and baking soda until smooth.
Mix in the sugars and flour until a thick batter has formed.
Fold in the fruit chunks.
Add 1 tablespoon of batter to each cupcake liner.
Top with 2 tsp of the jam, and cover with another layer of batter until the cupcake liners are ⅔ of the way full.
Bake for 22-25 minutes, or until cooked through.
Cool before serving.
