Preheat the oven to 350°F, and grease a 9×13-inch pan.
In a large bowl, use a hand mixer to combine the cake ingredients. Mix until just combined following the box instructions.
13.25 ounces lemon cake mix, 1 cup water, ⅓ cup vegetable oil, 3 eggs, 3.4 ounces vanilla instant pudding, ¾ cup sour cream
Transfer the batter to the pan, and follow box directions for baking (mine said 26-31 minutes). Use a toothpick to check if the cake is done (it should come out clean).
To Make the Lemon Filling:
Whisk the sweetened condensed milk with the lemon juice. Avoid letting it sit too long because it will firm up.
14 ounces sweetened condensed milk, ½ cup freshly squeezed lemon juice
Use a wooden spoon handle to poke holes in the cake, then pour the mixture over it and smooth into an even layer.
Let the cake cool completely before adding the whipped topping.
To Apply the Whipped Topping:
Spread the whipped topping evenly over the cooled cake using a spatula.
8 ounces whipped topping
Garnish with lemon slices, slice and serve!
