How to Make Unicorn Poke Cake
Let’s create something magical!
Step 1: Bake the Cake
Prepare and bake the vanilla cake according to package instructions in a 9×13-inch pan.
Allow it to cool for about 15–20 minutes — it should still be slightly warm but not hot.
Step 2: Poke the Holes
Using the handle of a wooden spoon, gently poke holes all over the cake, spacing them about 1 inch apart.
These holes are where all that colorful magic will soak in!
Step 3: Prepare the Gelatin
In separate bowls, dissolve each gelatin flavor in 1 cup of boiling water. Stir until fully dissolved.
Step 4: Add the Color
Carefully pour each gelatin flavor into different sections of the cake, alternating colors randomly for a beautiful unicorn effect.
Don’t worry if it looks messy — that’s part of the magic!
Step 5: Chill
Refrigerate the cake for at least 3–4 hours (or overnight). This allows the gelatin to fully set inside the cake.
Step 6: Frost and Decorate
Spread whipped topping evenly over the chilled cake.
Top generously with rainbow sprinkles and edible glitter if desired.
For extra fun, tint small portions of whipped topping with pastel food coloring and swirl them together before spreading.
