Spray pan with cooking spray. Put sugar in pan and shake and turn pan to cover the entire interior of the pan uniformly. Do this over the sink just in case some spills.

Combine cake mix with Jello, milk, butter, lemon juice, and vanilla or cream cheese emulsion.

Add eggs, 1 at a time. Beat 2 minutes, scraping bowl sides down. Fold in lemon zest.

Pour batter into prepared pan and bake according to package directions, checking often towards the end of cooking time. Do not over bake.

Cool completely before icing with Cream Cheese Icing or Lemon Glaze

Beat cream cheese with butter, then add sugar, vanilla and milk. Combine well.

Adjust consistency by adding more milk if desired. If icing is too thin add more sugar. Spoon over cake top, letting it ooze down sides just a little. Add sprinkles if desired.

Mix together to form glaze. Add more liquid or more sugar to achieve desired consistency. Pour slowly all over cake
