An easy, delicious summer dessert!
In a medium-sized bowl, combine cake mix, dry pudding mix, water, oil, eggs, lemon zest and lemon juice. Beat on medium – high speed until all ingredients are well blended. Use a spatula to mix the batter from the bottom of the bowl to the top.
Pour the batter into a 9-inch by 13-inch pan that has been sprayed with nonstick cooking spray and bake at 350°F for about 25-35 minutes until cake is set. Test cake by inserting a toothpick into the center. If the toothpick comes out clean, the cake is done. (I would check at 25 mins, especially if you're using a glass pan.)
While the cake is cooling, dissolve gelatin in boiling water in a small bowl, stirring constantly.
