- 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.
Step 4: Spread the whipped topping evenly on top cake and arrange the berries in a flag pattern as shown.
Slice, serve, and enjoy!
Cover and refrigerate leftover 4th of july poke cake for up to 3 days.
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).
Flag Poke Frequently Asked Questions
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.
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.
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.
