Preheat oven to 350° Mix cake mix, eggs, and oil. Add the strawberries and spoon onto baking sheet lined with parchment paper. Bake for 10-12 minutes. You want to remove them before they turn brown.
Dice 1/3 cup of fresh strawberries and place them in a bowl. Use a potato masher to mash them a little and place them in the refrigerator for about an hour so it will make fresh strawberry juice. You will need 1/3 cup of the juice. (You may need to use more strawberries depending on ripeness.)
Once you have 1/3 of fresh strawberry juice, mix the powdered sugar, oil, and strawberry juice until smooth. Add the diced strawberries and mix. Place cookies on a bakers rack and pour icing onto the cookies. Place a bowl under to catch the excess icing.
Once the icing is dry, store them in an airtight contain in the refrigerator. This recipe makes approximately 40 cookies.
