Preheat oven to 325 degrees F.

Add the cake mix and strawberry soda to a mixing bowl. 

Use a handheld mixer and mix batter on low for 2 minutes. 

Line a cupcake pan with liners and fill each one up half way with the cupcake batter. 

Bake 18-23 minutes or until a toothpick inserted in the center comes out clean. 

While the cupcakes are baking chop the strawberries into small pieces.

Let the cupcakes cool completely, then add a circle of whipped topping around the edge and fill with chopped strawberries.
