How to Make the Perfect Lemon Jell-O Poke Cake

There’s something incredibly nostalgic and refreshing about a Lemon Jell-O Poke Cake. It’s the kind of dessert that’s light, bright, and bursting with citrusy goodness — perfect for spring and summer gatherings or whenever you crave a sweet zing. If you’re looking to impress with minimal effort, this classic cake is your new go-to.

What is a Poke Cake?

A poke cake is a simple dessert made by baking a cake, poking holes in it, and pouring in a liquid (usually Jell-O, pudding, or sweetened condensed milk). The liquid seeps into the cake, making it moist, flavorful, and colorful. Lemon Jell-O takes this cake to a whole new level of tangy deliciousness.


Ingredients You’ll Need

For the cake:

  • 1 box (15.25 oz) white or yellow cake mix
  • Ingredients listed on the cake mix (typically eggs, oil, and water)

For the filling:

  • 1 box (3 oz) Lemon Jell-O gelatin
  • 1 cup boiling water
  • 1/2 cup cold water

For the topping:

  • 1 tub (8 oz) whipped topping (Cool Whip), thawed
  • Optional: Fresh lemon zest, lemon slices, or sprinkles for garnish

Step-by-Step Instructions

1. Bake the Cake

Prepare the cake mix according to the package instructions. Bake it in a 9×13-inch pan until a toothpick comes out clean. Let it cool for about 15 minutes.

2. Poke the Holes

Once the cake is slightly cooled, use the handle of a wooden spoon or a large fork to poke holes all over the surface — spacing them about an inch apart.

3. Make the Jell-O Mixture

In a bowl, dissolve the Lemon Jell-O in 1 cup of boiling water. Stir until fully dissolved, then add 1/2 cup of cold water. Mix well.

4. Pour the Jell-O

Slowly pour the Jell-O mixture over the poked cake, allowing it to seep into all the holes. This is where the magic happens! Refrigerate the cake for at least 2 hours, or until the Jell-O is set.

5. Top it Off

Once the cake is fully chilled and set, spread the whipped topping evenly over the top. Add lemon zest or thin lemon slices for an extra pop of flavor and visual appeal.
