- Lemon Jello gelatin: A box of lemon gelatin is the best way to add lots of lemon flavor to this recipe. Make sure you are using the instant lemon Jell-O and not instant lemon pudding mix.
- Cold water: Added to the Jello mixture after the gelatin has dissolved in boiling water.
- Whipped topping: A tub of whipped topping is used to add a creamy layer on top of the cake. You can substitute whipped heavy cream or whipped cream if needed.
- Lemon zest: A little lemon zest is used as a garnish for the cake, adding a burst of fresh lemon flavor. Sprinkle on top of the whipped topping before serving. You could also garnish with lemon slices or dollops of lemon curd.
How To Make Lemon Poke Cake
Lemon Poke Cake is a simple and delicious recipe made with just a few ingredients.

Step 1. Prepare cake
Preheat oven to 350 degrees and great as 9 x 13 inch baking dish with nonstick cooking spray. Use a hand mixer to mix lemon cake in a large mixing bowl according to package instructions.
Pour batter into prepared baking dish. Bake cake for 25-30 minutes or until a toothpick comes out clean.
Step 2. Prepare Jello mixture
In a medium bowl, dissolve lemon Jello in 1 cup boiling water. Then, stir in ½ cup cold water until well mixed.
Step 3. Poke holes and add Jell-O
Once the cake is baked, use the end of a wooden spoon to poke holes all over the surface of the cake.
Then, pour the prepared Jello mixture evenly over the cake, ensuring it seeps into the holes.
Allow the cake to cool to room temperature.
Step 4. Top with whipped topping
Spread the whipped topping over the cooled cake. Refrigerate the cake for at least 2 hours or until the whipped topping is firm.
Before serving, garnish with lemon zest for an extra burst of flavor. Cut the cake into squares and serve!
