Can I make these without white chocolate?

While the white chocolate adds a distinctive flavor and texture, you could substitute with milk chocolate for a different taste profile. The bars won't be traditional "unicorn" bars but will still be delicious! You may need to adjust the sugar slightly as white chocolate is sweeter than milk chocolate.

Why did my sprinkles bleed into the batter?

This usually happens when using liquid food coloring-based sprinkles. For best results, use oil-based colored sprinkles or "jimmies" which hold their shape and color during baking. Avoid using nonpareils in the batter as they tend to bleed more.

Can I make these gluten-free?

Absolutely! Simply swap the all-purpose flour for a 1:1 gluten-free baking flour blend. The texture might be slightly different, but they'll still be delicious. Just ensure your sprinkles and white chocolate are also gluten-free.

How far in advance can I make the Unicorn Bars?

You can make the blondie base up to 2 days ahead and store well-wrapped at room temperature. For best results, frost and decorate the bars the day before or the day you plan to serve them, as the colors in the design will remain more vibrant.

Instructions

Prepare Baking Dish and Oven
Grease a 13 x 9-inch baking dish or line it with parchment paper. Preheat the oven to 325°F.
Melt Butter and Chocolate
Place butter and chopped white chocolate in a saucepan. Melt over low heat, stirring occasionally. Let the mixture cool for about 10 minutes. It’s normal for the butter and chocolate to separate; they will combine again when sugar is added.
Combine Sugar and Eggs
Add granulated sugar to the cooled butter and chocolate mixture, stirring until well-combined. Incorporate eggs one at a time, stirring well after each addition.
Mix in Dry Ingredients and Sprinkles
Stir in all-purpose flour, salt, and vanilla until well-combined. Fold in the rainbow sprinkles for a touch of color and fun.
Bake the Brownie Layer
Pour the batter into the prepared baking dish and bake in the preheated oven for 30 to 35 minutes, or until a cake tester comes out clean. Allow the brownie layer to cool completely on a wire rack before frosting.
Prepare the Frosting
In a mixing bowl, beat the softened butter for 2 minutes. Gradually add powdered sugar, alternating with cream, until a spreadable consistency is achieved. Add vanilla and beat for another 2 minutes for smooth frosting.
Color the Frosting
Set aside 1/2 cup of the frosting and tint it blue with a few drops of food coloring. Divide the blue frosting into two portions and tint one part purple using a drop of red food coloring. Adjust the coloring as needed to achieve the desired shades.
Frost and Decorate
Spread the remaining white frosting evenly over the cooled brownie layer. Place the blue and purple frostings into separate piping bags with a small snipped tip. Pipe diagonal blue lines across the bars, then pipe purple lines in the opposite direction to create a diamond pattern. Finish with a sprinkle of rainbow sprinkles on top.
Serve and Enjoy
Slice into bars, serve, and enjoy the magical flavor of Unicorn Bars!

Notes

Store Unicorn Bars in a single layer inside an airtight container in the refrigerator for 3-5 days.
For longer storage, freeze the bars in a single layer wrapped in parchment paper inside a freezer-safe container for up to 1-2 months.
