  • Bake and cool the cake. Pour the batter into the prepared baking dish and spread it evenly. Then, bake the cake for 22-26 minutes, or until a toothpick inserted into the center comes out clean. Allow the cake to cool completely in the pan at room temperature for at least 1 hour before frosting.

  • Make the frosting. In a large mixing bowl, beat the milk and instant French vanilla pudding with a hand mixer for 2-3 minutes until smooth. If using, add the lemon extract and mix until combined. Gently fold the defrosted Cool Whip until the mixture is smooth and fluffy. Add pink food coloring to achieve your desired shade of pink.
  • Assemble and cool. Once the cake has cooled completely, spread the frosting evenly over the top of the cake. Refrigerate the cake for at least 2 hours until the frosting is set and the cake is chilled.

Notes

Remember to let your egg whites and milk sit out until they are at room temperature before mixing to mix better with the other ingredients.
Because of the yellow ingredients, the cake may look coral or orange when you first add the pink food coloring. You can add more pink dye for a pinker color or leave it as it is.
For an extra zesty flavor, add some lemon zest to the cake batter. It will give a fresh lemon taste without changing the texture.
It’s best to make this cake ahead of time to let the flavors blend together.
Use a sawtooth knife to get perfect slices, and clean it after each cut.

More Tips:

Remember to check your cake a few minutes before the suggested bake time, as oven temperatures can vary. Use a toothpick to test if the cake is done by inserting it into the center; if it comes out clean, the cake is ready.

Defrost the Cool Whip in the refrigerator, not on the counter, to prevent it from becoming too runny and to make sure that your frosting is light and fluffy.

Be gentle when folding in the Cool Whip to maintain the frosting’s airy texture, as overmixing can deflate it.

For the best texture, the cake should be chilled for at least 2 hours after frosting to help the flavors meld and the frosting set.

Serving Suggestions

Easy Pink Lemonade Cake pairs well with Prosecco Sangria with Fresh Berries, Redskin Potato Salad, Buttermilk Honey Chicken Tenders, vanilla ice cream, strawberry sorbet, or lemonade.

Here are some great ingredient alternatives you can try for this recipe:

  • Lemon cake mix: You can use white or yellow cake mix with 1 tablespoon of lemon zest.
  • Instant lemon pudding: Replace it with vanilla pudding and add 1 teaspoon of lemon extract. Look for it near the gelatin and other pudding mixes in the baking aisle.
  • Egg whites: Swap with 3 whole eggs for a richer cake.
  • Cool Whip: Use homemade whipped cream, stabilized with 1 tablespoon of powdered sugar. This can usually be found in the freezer section of your grocery store. Make sure to defrost it in the refrigerator before using it.

Storage Instructions

Wrap the cake in plastic or put it in a sealed container. You can keep it in the fridge for up to 5 days.

This cake doesn’t freeze well because the Cool Whip frosting can get watery when it thaws.
