Soft cookie cups topped with tall pastel buttercream swirls and shamrock sprinkles!
These Lucky Charms Swirl Cookie Cups are a kid’s St. Patrick’s Day dream. Soft cookie bases that actually taste like Lucky Charms, topped with tall swirls of pastel buttercream and finished with shamrock sprinkles. They’re bright, festive, and completely leprechaun-ready.
Flavor Profile
The cookie base is marshmallowy and buttery and lightly sweet with that classic sugar-cookie softness in the center and golden edges around the rim. The buttercream is fluffy, smooth, and rich without feeling heavy. Together, it’s soft meets creamy with a clean vanilla finish and just a little sprinkle crunch on top.

Lucky Charms Swirl Cookie Cups
Ingredients
- 1 package Lucky Charms cookie dough
- 2 sticks salted butter, softened
- 3½ cups powdered sugar
- 4 to 6 tablespoons heavy cream
- 1 teaspoon vanilla extract
- Pastel food coloring
- Shamrock sprinkles
Instructions
- Preheat oven to 350°F. Lightly spray a mini muffin tin.
- Separate the cookie dough into the 12 pre-cut rounds. Cut each round in half so you have 24 pieces total.
- Press one piece into each mini muffin well, pressing into the bottom and slightly up the sides to form a cup shape.
- Bake for 10 to 13 minutes, until lightly golden around the edges.
- Let the cookie cups cool in the pan. Gently twist each one to loosen it and remove them from the tin.
- For the buttercream, beat the softened butter until smooth and creamy. Add powdered sugar, heavy cream, and vanilla. Beat until light and fluffy, adding more cream as needed for a smooth, pipeable consistency.
- Divide the buttercream into three bowls. Leave one white and tint the other two with pastel colors of your choice.
- Spoon the three colors side by side into one piping bag fitted with a 1M star tip. This allows the colors to pipe out together and create a soft swirl effect.
- Pipe tall swirls into each cooled cookie cup.
- Finish with shamrock sprinkles and serve.
