How This Unicorn Poke Cake Became My Favorite Party Trick

If you’ve ever been tasked with bringing a dessert to a birthday party, school celebration, or even just a weekend gathering where “something fun” is expected, let me introduce you to my secret weapon: the Unicorn Poke Cake. It’s bright, playful, ridiculously easy to make, and every bite is filled with creamy, colorful magic. I’ve made this cake for kids’ birthdays, baby showers, and yes—even once for a brunch where I wanted to bring something with a little extra sparkle.

The beauty of this cake is that it looks like you spent hours on it, but it’s made with boxed cake mix, pudding, and whipped topping. Trust me—if you can stir and swirl, you can make this cake.

Why This Unicorn Poke Cake Works Like a Charm

There are a few reasons I keep coming back to this recipe, and none of them require pastry chef skills:

• Boxed mix makes it foolproof: You get consistent results every time.
• The pudding layer is creamy and vibrant: Each slice has a dreamy texture and color surprise.
• It’s totally customizable: Change the colors, add sprinkles, make it your own.
• Kids absolutely love it: The name alone gets them excited, and the colors seal the deal.
• No special equipment required: Just a mixing bowl, spoon, and 9×13 pan.

How I Make This Magical Unicorn Cake

1. Bake the Cake

I start by preparing the white cake mix according to the package instructions, then pour the batter into a greased 9×13-inch pan. Bake it until a toothpick comes out clean—usually around 25 to 30 minutes. Once it’s out of the oven, I let it cool for about 10 minutes.

2. Poke the Cake

While the cake is still slightly warm, I use the handle of a wooden spoon (or a thick straw) to poke holes all over the surface. I space them about an inch apart, making sure they go deep enough to hold that pudding magic. You don’t need to overthink this part—random holes work just fine.

3. Make the Pudding

In a large bowl, I whisk together the two boxes of instant vanilla pudding with the four cups of cold milk. As soon as it starts to thicken—about two minutes in—I divide it evenly between three bowls.

4. Add the Unicorn Colors

I tint each bowl of pudding with a different gel food color. Pink, purple, and turquoise are my go-to choices, but you can absolutely get creative here. Once the pudding is colored, I spoon or drizzle it into the holes in the cake, alternating colors for a tie-dye effect. Then I gently spread any remaining pudding over the top of the cake.

5. Chill Time

This part takes patience, but it’s worth it. I cover the cake and refrigerate it for at least two hours, or until the pudding is fully set. Sometimes I even make it a day ahead—more chill time = better flavor and texture.

6. Add the Topping

Right before serving, I spread the whipped topping evenly across the surface of the cake. Then comes the fun part: decorating! I go wild with rainbow sprinkles, edible glitter, or even little candy stars. Basically, if it sparkles or makes you smile, it belongs on top.

My Pro Tips for a Next-Level Unicorn Poke Cake

• Use gel food coloring: It gives you those bright, vibrant colors without watering down the pudding.
• Clean the spoon handle between pokes: Helps the holes stay neat and avoid tearing the cake.
• Chill overnight if possible: It sets beautifully and the flavors really come together.
• Want extra flair? Add a layer of colored sugar or drizzle on tinted white chocolate before serving.

How I Serve It (and When)

This cake is the definition of party-ready, but here are a few of my favorite occasions to pull it out:

• Birthday parties (especially for unicorn-obsessed little ones)
• Gender reveal parties or baby showers
• Weekend family get-togethers when I want something different
• Dessert tables that need a showstopper
• Random weeknights when I need a little sparkle in my life

It holds up really well for a couple of days in the fridge, so I’ll even sneak a square for breakfast with coffee if I’m being honest.

FAQs From My Kitchen

Q: Can I use homemade cake instead of a mix?
Absolutely! A simple white or yellow cake recipe works great. Just make sure it’s sturdy enough to hold up to the pudding soak.

Q: Does it have to be vanilla pudding?
Not at all. White chocolate or cheesecake pudding are great options too—anything that’s light in color and flavor will work.

Q: How far ahead can I make this?
You can make and chill the cake (without the whipped topping) up to two days in advance. Add the topping and decorations the day of serving for best results.

Q: Do the colors bleed into each other?
A little bit, but that’s part of the fun. The swirls and color mixing give it that dreamy unicorn vibe.

Q: Can I freeze it?
I wouldn’t recommend freezing—the pudding and whipped topping don’t thaw well. This one’s best enjoyed fresh from the fridge.
