This vibrant lime cake combines a moist white cake base with lime gelatin gently poured into evenly spaced holes, creating a refreshing burst of flavor in every bite. Topped with luscious whipped cream and bright lime zest, the dessert offers a perfect balance of tartness and sweetness. Chilled for several hours, it delivers a cool, festive treat ideal for celebrations, enhanced by optional garnishes like green sprinkles or lime slices.

The first time I made this poke cake, my kitchen smelled like sunshine and margaritas combined. My roommate walked in mid-bake and asked if Id taken up bartending. The bright green color against the snowy whipped topping makes everyone smile before they even take a bite.

I brought this to our neighborhood St. Patricks Day potluck last year, and it vanished before the corned beef even hit the table. My neighbor Linda asked for the recipe three times because she couldnt believe something so pretty came from a box mix. Now its the one thing everyone actually asks me to contribute.

Ingredients

  • White cake mix: The foundation that soaks up all that lime goodness without getting soggy
  • Water, vegetable oil, and eggs: Classic ingredients that transform the mix into a tender, light cake base
  • Lime gelatin: The magic that makes every bite incredibly moist and delivers that signature tangy flavor
  • Boiling and cold water: Essential for properly dissolving the gelatin so it sets perfectly inside the cake
  • Whipped topping: Creates that cloud-like layer that balances the bright lime with creamy sweetness
  • Lime zest: Fresh aromatic oil that makes the cake taste like you squeezed actual limes into it

Instructions

Bake the cake foundation:
Preheat your oven to 350°F and grease a 9x13-inch pan like your life depends on it. Beat the cake mix with water, oil and eggs for a full two minutes until its silky smooth. Pour it in and bake 28 to 32 minutes until a toothpick comes out clean.
Prep the lime infusion:
While the cake cools for exactly 15 minutes, dissolve the lime gelatin in boiling water. Stir in the cold water and let it cool slightly but dont let it start setting up.
Poke and pour:
Use the handle of a wooden spoon to poke holes all over the warm cake, about an inch apart. Slowly pour the lime gelatin over the surface, watching it disappear into all those little wells you created.
Chill and crown:
Refrigerate for at least 2 hours so the gelatin transforms into pockets of lime perfection. Spread the whipped topping evenly over the top and finish with lime zest and whatever green decorations make you happy.

Last March my daughter declared this her official birthday cake request, completely bypassing chocolate for the first time in eight years. Seeing her face light up at that bright green slice made me realize comfort food doesnt always have to be warm and brown.

Make-Ahead Magic

This cake actually improves after sitting in the refrigerator overnight. The gelatin has time to fully mingle with the cake crumb, creating pockets of lime flavor that taste even better the next day.

Serving Suggestions

Cut small squares because this cake is richer than it looks. The cool creamy topping against the bright lime cake pairs surprisingly well with a hot cup of coffee or even something stronger if the occasion calls for it.

Decoration Ideas

Beyond the standard green sprinkles, try arranging fresh lime slices in a pattern across the top. A little extra zest around the edges makes it look like something from a bakery window.

  • Get creative with edible gold or shamrock-shaped sprinkles for extra festivity
  • Consider piping the whipped topping in dollops instead of spreading it for a fancier look
  • Keep the cake chilled until serving time for the cleanest slices
