Prepare the strawberry funfetti cake mix according to package instructions, swapping whole milk for water and melted butter for oil.
Pour batter into a greased 13x9 baking pan.
Bake at 350°F for about 30 minutes or until a toothpick comes out clean.
Allow the cake to cool completely.
Using a small round shot glass, cut out mini cake circles.
Spread cream cheese frosting onto one cake round and sandwich another layer on top.
Frost the top layer and sides lightly.
Roll or dunk the cakes into rainbow praline sprinkles until fully coated.
Serve immediately or chill slightly before serving for an even firmer texture.
