Ingredients for 4th of July poke cake.
  • White cake mix— plus water, eggs, and oil as called for on the box. I used Pillsbury but any white cake mix will work.
  • Cherry Jello mix— or strawberry Jello
  • Berry blue Jello mix— or blue raspberry
  • Water— you will need both boiling water and cold water to prepare the jello mix before pouring it onto the cake.
  • Cool Whip— thawed in the fridge overnight. You can substitute with homemade whipped cream if you prefer but keep in mind that it doesn’t keep as well as Cool Whip does so you should wait to add it until you are ready to serve.
  • Fruit— fresh blueberries and fresh, sliced strawberries for creating the American flag on top

How to Make 4th of July Cake with Jello

This section shows you how to make the recipe with step-by-step photos and instructions. For the full printable recipe, see the recipe card below. 

Step 1: Prepare the cake mix in a 9×13 pan as directed on the package. Allow the cake to cool for 15 minutes after removing it from the oven.

Step 2: Meanwhile, prepare the jello mixes by combining each with 1 cup of boiling water, whisking until dissolved, then whisking in ½ cup cold water. Using the end of a wooden spoon or a large straw, poke holes throughout the cake. Spoon the jello in the holes, alternating between blue and red jello.

Step 3: Cover and refrigerate the cake for at least 3 hours to allow the jello to set.

Tips and Tricks

  • If you have a food syringe it makes filling holes with jello super neat and easy. Otherwise, a spoon works just fine.
  • Try adding red, white, and blue sprinkles to the cake mix for a funfetti look.
  • Rather skip the fruit? You can top the cake with red, white, and blue sprinkle instead (but it won’t be a flag cake).
  • Switch up the jello flavors and colors for different holidays and events, like we did for this red and green Christmas poke cake.

Flag Poke Frequently Asked Questions

Can I make this poke cake ahead of time for my party?

This cake is perfect for making ahead because it actually tastes better the next day after the jello has more time to infuse the cake with flavor. Prepare the cake the day before you plan on serving it and let it chill overnight. Then add the whipped topping and fruit just before serving.

What is the best way to poke holes in a poke cake?

I have found that the handle of a wooden spoon is usually the perfect size for poking holes in a poke cake. If you don’t have one no worries, you can use a chopstick, large fork, or straw instead.

How many holes do you poke in a poke cake?

Typically I have found 40-55 holes to be the perfect amount for poke cakes. However, if you are using a fork or something else that creates small holes you will like need more.

  1. I have the original 1990s recipe.l found it online.And the reason that l know it’s the original recipe is because the website that l had gotten the original recipe from.Had taken a picture of the original recipe. I don’t know if I can say another website on here.lf you want to know the website that l got the original recipe from l will tell you by email.If l get permission from the owner(s)to put up the website on here.Then please owners email me.And l will gladly put it on up.NOT a problem.Thank you,

  2. Hello, I know it’s last minute, I have the cake in the fridge now. Planning on bringing over to in-laws, should I decorate with whipped cream and fruit before going over or should I leave it in the fridge as is and by the time night rolls around after dinner, then head back to decorate and bring over straight away? My guess is no one will eat the cake until 7-8 after everyone is done with dinner. Just wondering, all I have is a cooler because my mil most likely doesn’t have room in her fridge for it. I didn’t want the flag to get ruined if it doesn’t stayed chilled enough.

    1. Sorry for the late reply but I would recommend keeping it in the fridge rather than the cooler for as long as possible and topping it just before serving.

  3. I’ve made a few poke cakes each time it ends up being too moist and soggy! Help please!
