This festive lime cake blends zesty gelatin soaked into a moist white cake base, topped with a smooth vanilla pudding and whipped cream layer. Chilled for hours, the cake delivers a refreshing burst of citrus balanced with creamy textures and festive green sprinkles. Easy to prepare and perfect for celebrating the holiday with bright colors and lively flavors.
My best friend Sarah announced she was hosting her first St. Patricks Day party and needed something green that actually tasted good. We stood in her tiny kitchen laughing about all the terrible green food we'd seen over the years, so I volunteered to experiment with this poke cake idea. The whole apartment smelled like fresh limes while it chilled in the fridge, and by party time, people were actually going back for seconds instead of politely pretending to enjoy it.
Last March my cousin brought store bought cookies to our family gathering, and my aunt looked so disappointed that I promised to handle dessert this year. Now everyone expects this cake at every holiday, and honestly, I don't mind because it's become this little tradition that makes the house feel festive.
Ingredients
- White cake mix: I've tried scratch versions but the box mix gives such a tender crumb that holds up beautifully to all that liquid
- Water, oil, eggs: Standard cake mix ingredients, but don't skip beating the full two minutes or the texture won't be right
- Lime gelatin: The bright green color looks so cheerful, and the wobbly texture pairs perfectly with the soft cake
- Boiling and cold water: The temperature difference helps dissolve the gelatin properly before you pour it over the cake
- Cold whole milk: I tried lowfat once and the pudding never set quite right, so stick with whole milk
- Instant vanilla pudding mix: Cooked pudding won't work here, it needs to be the instant kind that sets up cold
- Whipped topping: Homemade is fine but the tub stuff spreads so easily and stays stable in the fridge
- Lime zest and sprinkles: These are purely for show but they make such a difference when everyone pulls out their phones for pictures
Instructions
- Bake the cake base:
- Heat your oven to 350°F and grease a 9x13 pan really well, then mix the cake ingredients on medium speed for exactly two minutes until it looks silky smooth. Pour it in and bake 28 to 32 minutes until a toothpick comes out clean, but don't overbake or it'll get tough.
- Poke those holes:
- Let the cake cool just ten minutes, then use a wooden spoon handle to make holes about an inch apart all over the surface. Don't press too hard or you'll hit the bottom, and work quickly while the cake's still warm so it absorbs everything.
- Make the lime mixture:
- Stir the gelatin into boiling water until completely dissolved, then whisk in the cold water and let it cool slightly. Pour it slowly over the cake so it can soak into all those little holes you made.
- Let it set:
- Refrigerate for at least an hour, and if you can wait longer, even better because the lime flavor intensifies and the texture firms up beautifully.
- Prepare the topping:
- Whisk the cold milk and pudding mix for two minutes until it starts to thicken, then gently fold in the whipped topping until no white streaks remain. Spread it over the chilled cake and add your garnishes before chilling another 30 minutes.
My seven year old niece helped me make this last year and was absolutely fascinated by poking all the holes in the cake. She told everyone at dinner that she made the magic happen, and honestly, she wasn't wrong about how much fun the process is.
Make It Your Way
Sometimes I swap the lime gelatin for lemon or orange depending on what's in the pantry, and it's just as good. The color isn't as festive for St. Patricks Day, but for summer potlucks, the lemon version is always the first to disappear.
Serving Strategy
Cutting this cake can be messy because the layers slide around a bit, so I use a sharp knife and wipe it clean between every few slices. For parties, I cut it in the kitchen and arrange pieces on a platter so it looks tidy instead of having people dig in and make a mess.
Storage Solutions
This cake actually tastes better on day two because all the flavors have time to mingle and settle. Keep it covered in the refrigerator and it'll stay fresh for three to four days, though it never lasts that long at my house.
- Press a piece of plastic wrap directly against the cut edges to prevent them from drying out
- If you're transporting it, chill the covered cake in the fridge overnight so it's firm before moving
- The lime flavor gets more pronounced the longer it sits, so don't add extra lime juice unless you really love that tart punch
Hope this bright green cake brings some luck and laughter to your table.
