Ingredients
- White cake mix: which is your base providing structure and a neutral sweet flavor that enhances citrus notes
- Vegetable oil: to keep the cupcakes tender and moist ensuring they do not dry out
- Egg whites: for lightness and to help the cupcakes rise well
- Lemon lime soda: adds carbonation and natural citrus flavor giving the cupcakes a delicate fizz and moist crumb
- Lime gelatin mix: adds tang and also helps boost citrus flavor in the cake and frosting
- Salted butter: for richness in the frosting giving a creamy texture and balanced flavor
- Cream cheese: softened for smoothness and a slightly tangy taste that complements lime
- Powdered sugar: to sweeten and thicken the frosting to the perfect consistency
- Vanilla: for enhancing the overall sweetness and tying flavors together
- Half and half: to adjust frosting texture for perfect piping smoothness
- Green food coloring: to give the frosting a fresh zesty appearance
- Green sprinkles: for a fun finishing touch that adds texture and visual appeal
Instructions
- Prepare the Cupcake Tin:
- Preheat your oven to 350 degrees Fahrenheit. Line your muffin tin with cupcake liners to ensure easy removal and neat presentation of cupcakes.
- Mix the Cupcake Batter:
- In a large mixing bowl combine the white cake mix, vegetable oil, egg whites, and lemon lime soda. Use a hand mixer on medium speed and blend until the ingredients are well incorporated but avoid overmixing to keep batter light.
- Add the Gelatin:
- Gently stir in the lime gelatin mix. This adds a subtle citrus boost and helps with texture. Mix just enough to combine to avoid toughening the batter.
- Fill the Cupcake Liners:
- Divide the batter evenly among the cupcake liners in your muffin tin. Fill each liner about two thirds full to allow space for rising.
- Bake and Cool:
- Bake the cupcakes for 18 to 20 minutes until a toothpick inserted in the center comes out clean. Let them cool completely before frosting to avoid melting the frosting.
- Cream the Frosting Base:
- Using a hand mixer, beat the softened butter and cream cheese together until fluffy and smooth which takes about two minutes.
- Flavor the Frosting:
- Add the vanilla extract and lime gelatin mix to the butter and cream cheese and blend well to distribute the lime flavor.
- Sweeten and Adjust Consistency:
- Gradually add powdered sugar, one cup at a time, alternating with a tablespoon of half and half to achieve a smooth but firm frosting. Beat for about two minutes till stiff peaks form indicating the right consistency for piping.
- Color the Frosting:
- Add a drop or two of green food coloring to reach your desired shade of fresh lime green. Mix thoroughly for even color.
- Frost and Decorate:
- Transfer the frosting into a piping bag fitted with a round tip and pipe generous swirls onto the cooled cupcakes. Finish with green sprinkles for a festive appearance.

My favorite ingredient is the lime gelatin mix because it really elevates the simple cake mix into something special and unique. I still remember the first time my family tried these and everyone was surprised by the fresh flavor combination. It has become a celebratory recipe whenever the sun is shining.
Storage Tips
Store the cupcakes in an airtight container at room temperature for up to two days or refrigerate for up to five days. To maintain the best flavor and texture, bring refrigerated cupcakes back to room temperature before serving. If you want to keep them longer you can freeze the unfrosted cupcakes individually wrapped and thaw on the counter. Frosting is best made fresh but can be stored separately for a few days in the fridge.
Ingredient Substitutions
If you prefer, you can substitute the white cake mix for yellow or lemon cake mix for a slightly different base flavor. Using club soda or sparkling water in place of lemon lime soda works but you will lose some sweetness and citrus flavor. The lime gelatin mix can be swapped for lemon gelatin if you want a slightly different citrus note. Cream cheese frosting can be made dairy free by using vegan cream cheese and butter alternatives.
Serving Suggestions
These cupcakes are perfect served chilled on a hot summer day. They pair well with a cold glass of lemonade or iced tea. For a party, add fresh lime wedges and mint leaves on the side for added zest and aroma. They also make a bright finish to a brunch or outdoor picnic.

These lemon lime cupcakes are a bright, easy dessert perfect for summer gatherings. Make the cupcakes ahead and freeze unfrosted for quick treats any time.
