how to make Key Lime Jello Poke Cake
To make this delicious cake, follow these simple steps. Start by baking the cake mix according to the package instructions. Make sure to use room temperature ingredients for the best result. Once baked, let it cool slightly before poking holes all over the top of the cake.
Next, prepare the lime gelatin by dissolving it in boiling water and mixing in fresh lime juice. Pour this mixture over the cake, allowing it to seep into the holes for that amazing flavor. Once it’s fully absorbed, chill the cake in the fridge. Finally, top it with whipped topping, a sprinkle of lime zest, and a touch of green food coloring for that extra pop.
