With a chewy texture and sweet vanilla flavor, these cookies are perfect for celebrations, kids’ parties, or anytime you crave a whimsical treat.

Ingredients

Cookies

  • 1/2 cup unsalted butter (room temperature)
  • 1 cup sugar
  • 1 egg
  • 1 egg yolk
  • 1 tsp vanilla extract
  • 1 3/4 cup all-purpose flour (spooned and leveled)
  • 1/2 tsp baking soda
  • 1/2 tsp sea salt
  • 1/2 cup Lucky Charms marshmallows (plus extra for pressing into the tops)

Instructions

  1. Preheat the oven. Set your oven to 350°F (175°C) and line three baking sheets with parchment paper to prevent sticking and ensure even baking.
  2. Cream butter and sugar. In a medium bowl, use an electric mixer on medium speed to beat the softened butter and sugar together for about 2 minutes, until the mixture becomes light and fluffy, providing a tender base for your cookies.
  3. Add eggs and vanilla. Beat in 1 whole egg, 1 egg yolk, and 1 teaspoon vanilla extract for an additional minute, mixing just until everything is fully incorporated for a smooth dough.
  4. Combine dry ingredients. Add the all-purpose flour, baking soda, and sea salt to the wet mixture and mix gently until just combined to avoid overworking the dough.
  5. Fold in marshmallows. Gently fold in 1/2 cup of Lucky Charms marshmallows, saving some to press on top of the cookies before baking to give them a fun, colorful finish.
  6. Scoop dough onto sheets. Use a 3-tablespoon cookie scoop to portion the dough evenly onto the prepared baking sheets, spacing them to allow for spreading.
  7. Bake the cookies. Bake the cookies for about 10 minutes, rotating the pans halfway through to ensure even baking. The cookies should be slightly golden at the edges but still soft.
  8. Cool the cookies. Let the cookies cool on the baking sheets for 5 minutes to firm up, then transfer them to a wire rack to cool completely, which helps preserve their texture.
  9. Store or freeze. Store cooled cookies in an airtight container for 3-5 days to keep them fresh, or freeze for up to 3 months for longer storage.

Notes

  • For best texture, do not overmix the dough once the flour is added.
  • Press extra marshmallows on top of each cookie before baking for a festive look.
  • Cookies can spread slightly, so leave enough space between dough scoops on the baking sheet.
  • To freeze, place cookies in a single layer on a tray first, then transfer to an airtight container or freezer bag once frozen.
