The unicorn food trend is everywhere, and honestly, I love it. From hot chocolate and cakes to milkshakes, there’s no shortage of colorful treats — but we couldn’t find a unicorn blondie sundae, so we made one. Picture pink blondies, layered rainbow ice cream, and a generous sprinkle of candy and confetti. It’s the perfect birthday dessert, an over-the-top treat that’s as fun to serve as it is to eat.
We made two versions: a regular-sized sundae and a show-stopping super-sized version for celebrations when you want to go big.

Varies
Ingredients
- Rainbow Ice Cream:
- 2 cups heavy cream, cold
- 1 (14 oz) can sweetened condensed milk
- 2 teaspoons vanilla extract
- 1/4 teaspoon salt
- Pink Blondies:
- 2 sticks unsalted butter, room temperature
- 1/3 cup white chocolate chips
- 4 large eggs, room temperature
- 1 1/2 cups granulated sugar
- 2 teaspoons vanilla extract
- 2 cups all-purpose flour
- 1/2 teaspoon salt
- Food coloring (pink and other colors for ice cream layers)
- Toppings:
- Lollipops
- Candy necklaces
- Sprinkles
- Colorful marshmallows
- Sixlets or other small candy
Instructions
- For the ice cream: Whisk the cold heavy cream until stiff peaks form, using a stand mixer or by hand.
- Fold in the sweetened condensed milk, vanilla, and salt until fully combined.
- Divide the mixture evenly into several small bowls. Tint each bowl with desired food colors (neon pink, orange, yellow, green, turquoise, baby blue, purple, etc.), leaving one bowl white.
- Layer spoonfuls of each color and the white into a freezer-safe container with a lid. Gently tap the container to settle the layers and remove air pockets.
- Continue layering until all the mixture is used, cover, and freeze overnight.
- For the blondies: Preheat oven to 350°F (175°C). Grease a 9 x 13-inch baking dish.
- Melt the butter in a small saucepan over medium heat. Add the white chocolate chips and whisk until smooth and fully melted. Remove from heat and let cool slightly.
- In a stand mixer fitted with the whisk attachment, combine the eggs, sugar, and vanilla. Whisk on medium speed until light and fluffy, about 2 minutes.
- Add the butter and white chocolate mixture to the egg mixture and mix until combined. Fold in the flour and salt gently until the batter is uniform.
- Pour batter into the prepared pan and bake 30–35 minutes. Allow to cool, then cut into squares.
- To assemble the sundae: Arrange two blondie squares on a plate, top with several scoops of rainbow ice cream, add whipped cream, then finish with sprinkles and assorted rainbow candies.
