Tips for Making Delicious Cookies

Before you dive into this recipe, I’ve got some tips for you on making the best (and tastiest) cookies. If you’re interested, check them out. Otherwise scroll to the bottom.

Use Quality Ingredients

Use high-quality, fresh ingredients for the best cookie flavor and texture. You’ll for sure want to get fresh eggs, good quality butter, and pure vanilla extract (instead of imitation).

Measure Precisely

Flour is often the main dry ingredient in these cookies. Measure using the scoop-and-level method, as adding too much flour can result in dry baked goods.

Bring Cold Ingredients to Room Temp

Bring ingredients like butter, and eggs to room temperature before mixing. They will incorporate better, resulting in smoother batter and soft cookies. They don’t need to be warm; slightly cool to room temp is fine.

Avoid Overmixing

Mix the batter just until ingredients are combined, or the dry disappears into the wet. Overmixing can result in tough cookies.

Chill the Dough

Chilling the cookie dough in the fridge for the specified time (or even overnight) before baking allows the flavors to meld and the fats to solidify. This results in cookies with better flavor and texture. It also prevents them from spreading too much during baking.

Look for Golden Edges

Unless the recipe says otherwise, the edges of the cookies should turn a golden brown while the center remains slightly soft. This balance ensures a chewy texture without overbaking.

Cool Before Transferring

Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely. This helps them set and avoids them becoming too fragile and crumbling apart.

Here’s what you’re going to need for this Lucky Charm cookie recipe.


  • 1/2 cup butter, softened

  • 1 egg
  • 1 teaspoon vanilla
  • 2 cups all purpose flour
  • 1 teaspoon baking soda

You can get the marshmallows alone by searching online for “cereal marshmallows” – plus some stores sell them without the cereal. That’s how we made our Lucky Charms wreath and bark.

Store in an airtight container at room temperature for up to 5-7 days.

I haven’t frozen these, but I would say you can for a few months. When you bring them out of the freezer, let them rise to room temperature naturally as opposed to microwaving.
