In case you've never heard of a poke cake before, poke cake is basically just a cake with holes poked all over it after baking. Then a liquid or syrup (Jello in this recipe) is poured all over the top so that it can seep down into the holes and infuse into the cake. Then it's usually chilled for a few hours or overnight to create an unbelievably moist cake with unbeatable flavor.

Ingredients Notes & Substitutions

This recipe uses simple ingredients, so you may already have everything you need…

  • Vanilla Cake Mix – You can make a homemade vanilla cake mix, or even this classic yellow cake, but I usually just use a vanilla cake mix from the store.
  • Water, Eggs and Canola Oil – How much water, eggs and canola oil you use is actually dependent on the cake mix you use. Some recipes call for whole milk instead of water, and others call for butter instead of canola oil. Although I give rough ingredient amounts, be sure to follow the package directions for your cake mix.
  • Raspberry Jello Mix – I use raspberry-flavored gelatin mix for this recipe. Once you've baked the cake, you'll pour the Jello mixture on top of the cake and let it soak in for the ultimate raspberry-infused flavor!
  • Cool Whip – For the sake of ease, I use Cool Whip for this recipe. You can also use homemade whipped cream or Dream Whip.
  • Raspberries – Once it's chilled, I like to top off my raspberry poke cake with rinsed and dried, fresh red raspberries. They're so sweet and delicious!

How to Make Raspberry Poke Cake

Before getting started, preheat your oven to 350ºF, and grease up a 9×13 cake pan with nonstick cooking spray. Let's get started…

How to Bake the Vanilla Cake Mix

  1. Following the directions for your boxed cake mix, mix up the vanilla cake mix, water, oil and eggs in a large mixing bowl or in the bowl of an electric stand mixer on medium speed. Mix only until well combined, and take care not to over-mix your cake batter. This can weaken the structure and cause your cake to fall after baking.
  2. Pour your cake batter into the pan that you greased up in the first step.
  3. Bake it at 350ºF for around 28-33 minutes, or 'til a toothpick or cake tester inserted into the center comes out clean.

Once it's fully baked, remove from the oven and let the cake cool for about 15-20 minutes.

Add the Jello-Infused Topping

  1. While your cake is cooling, go ahead and whisk your raspberry gelatin mix into the boiling water in a large glass measuring cup or small bowl.
  2. Add in the cold water and whisk until the all of the Jello powder is fully dissolved. This may take a few minutes.
  3. Once your cake has cooled, use a fork to poke holes all over the top of the cake. Try to space your holes about 1-2 inches apart.
  4. Next, pour your Jello mixture slowly and evenly all over the entire cake. Let it cool completely.
  5. Use a spatula to spread the Cool Whip or other whipped topping over the top of your raspberry poke cake.
  6. Once you've spread your whipped topping over the cake, I recommend covering your poke cake with plastic wrap or a lid that fits your cake pan, and let it chill in the refrigerator for at least a few hours or even overnight.

You can serve the cake immediately, but poke cake is much better chilled. This gives the toppings plenty of time to soak in for the best Jello-infused poke cake you'll ever eat!

How to Serve Raspberry Jello Poke Cake

Once fully chilled, slice your raspberry poke cake into individual pieces, and serve it up with a pile of fresh raspberries. This easy dessert is just so sweet and refreshing, and the great thing is that it doesn't take very long to make!

You can also serve up your raspberry Jello cake with a mixed berry salad on the side. Bonus points if you throw in a scoop of homemade vanilla ice cream!

Expert Tips and Recipe FAQ's

Why did my cake fall in the middle?

Assuming that you didn't over-mix your cake batter, this is most likely because your cake was underbaked. Remember, it's only done when a toothpick or cake tester inserted into the center comes out clean.

Why is my poke cake soggy?

This can happen if you poke the holes on top of the cake too closely together. Try to keep them about 1-2 inches apart, no more and no less. If your holes are spaced adequately far apart, the cake is not underbaked, and you're still having issues, I recommend looking into this great guide with some tips and tricks on how to avoid a wet cake.

How do you store raspberry poke cake?

Raspberry poke cake is best stored in an airtight container for up to 2-3 days in the refrigerator. It's actually best served cold, so I chill mine for a while before serving anyways.

Can you freeze Jello cake?

Yes, you can freeze Jello cake. The best way to do this to freeze it before you add the whipped topping. Once you've poured on your Jello mixture, cover the cake with plastic wrap or with a lid that fits your cake pan. Then place it into the freezer for up to 1 month. When you're ready to serve, transfer it to the refrigerator to thaw overnight. Then spread the Cool Whip and serve!
