Why You’ll Love This Recipe

• Bright, colorful, and totally Barbie-inspired.
• Uses easy cake mix cookie dough—no fuss, just fun.

• Sweet vanilla frosting brings the whole cookie sandwich together.
• Customizable with sprinkles, food coloring, or sanding sugar.

Ingredient Notes

• Strawberry Cake Mix – This adds fruity flavor and a perfect Barbie-pink hue. For a more classic sugar cookie flavor, use white or vanilla cake mix instead.
• White or Vanilla Cake Mix – Great base for the ocean blue cookies. The lighter color makes the blue food coloring pop.
• Pink and Blue Food Coloring – Gel food coloring gives the most vibrant results without thinning the dough.
• Heavy Cream – Helps the frosting whip up light and fluffy. You can substitute with milk, but the texture will be a bit softer.
• Sanding Sugar – Optional, but adds sparkle and texture. Use pink, blue, or white to match the Malibu Barbie theme.

Before You Bake

Do I have to chill the dough before baking?
Nope! This cake mix cookie dough is ready to scoop and bake—no chilling needed unless you want extra thick cookies.

Can I use homemade cookie dough instead of cake mix?
Yes, but the texture and baking time may change slightly. Cake mix keeps things quick and consistent for this recipe.

What frosting should I use for these cookie sandwiches?
The homemade sweet vanilla frosting pairs perfectly, but store-bought vanilla or cream cheese frosting works in a pinch.
