For cupcakes: In a large bowl, stir together cake mix and gelatin mix. Make a well in the center and pour in mashed strawberries, oil, milk and eggs. Beat on low speed until blended. Scrape bowl and beat 2 minutes on medium speed. Pour batter into prepared cupcake pans.
Bake at 350 for 15-20 min or until cupcakes are done.
For the lemon cream cheese frosting: Cream together shortening, butter, and cream cheese until nice and smooth. Add vanilla into mixture and combine. Sift together sugar and salt, and slowly add to shortening, butter & cheese mixture. Add lemon juice and mix well.
Top each cupcake with a slice of strawberry and lemon zest. Voila!
