Homemade Focus
I’m a strong believer in the joy of homemade baking. There’s nothing quite like the satisfaction of creating something delicious from scratch.
This recipe is all about embracing that homemade goodness. It’s relatively simple to make, and the results are so rewarding. Simple is best.
Baking your own cookies allows you to control the ingredients and to ensure that you’re using high-quality, wholesome components.
Plus, it’s a fun and creative activity that you can share with your family and friends. It is a great activity for kids.
Flavor Goal
The primary flavor goal here is to create a harmonious blend of mint, chocolate, and sweet marshmallow. It is a unique taste.
The mint extract provides a refreshing coolness, while the chocolate chips add a rich, decadent touch.
The Lucky Charms marshmallows add a fun, chewy texture and a burst of familiar cereal sweetness.
We’re aiming for a cookie that’s both playful and delicious, a treat that’s sure to satisfy any sweet tooth.
Ingredient Insights
Let’s take a closer look at each ingredient. First, we have the softened butter, which provides richness and tenderness to the cookies.
I recommend using unsalted butter, as this allows you to control the amount of salt in the recipe. However, salted butter will also work.
The granulated sugar adds sweetness and contributes to the cookie’s texture. It helps to create a soft and chewy cookie.
The egg adds richness, moisture, and structure to the cookies. Make sure to use a large egg, as specified in the recipe.
The mint extract is what gives these cookies their refreshing minty flavor. Use pure mint extract for the best results.
The amount of mint extract you use can be adjusted to your liking. Start with a smaller amount and add more to taste.
The green food coloring is optional, but it adds a festive touch, especially for St. Patrick’s Day or other celebrations.
You can use gel or liquid food coloring. Start with a few drops and add more until you reach your desired shade of green.
The all-purpose flour provides the structure for the cookies. Make sure to measure the flour correctly, using the spoon-and-level method.
The baking soda and baking powder help the cookies to rise and become light and airy. Make sure they are fresh.
The cream of tartar helps to stabilize the egg whites and create a slightly chewy texture. It’s a secret ingredient.
The salt balances the sweetness and enhances the other flavors. Don’t skip the salt! It’s a crucial ingredient in baking.
The mint chocolate chips add a burst of cool, minty chocolate flavor to the cookies. You can use any brand of mint chocolate chips you prefer.
And finally, the Lucky Charms Marshmallows add a fun, colorful, and chewy element to the cookies. You can separate the marshmallows from a box of Lucky Charms cereal.
Essential Equipment
This recipe requires some basic baking equipment. You’ll need a cookie sheet to bake the cookies.
I recommend lining the cookie sheet with parchment paper to prevent sticking and make cleanup easier. Parchment is very convenient.
You’ll also need a mixing bowl to cream together the butter and sugar, and a separate bowl to combine the dry ingredients.
A mixer (either a stand mixer or a hand mixer) is helpful for creaming the butter and sugar and incorporating the other ingredients.
Measuring cups and spoons are essential for accurate ingredient proportions. Accurate measuring is key.
A spatula is helpful for scraping down the sides of the bowl and ensuring that everything is evenly mixed.
And finally, a cooling rack is necessary for cooling the cookies completely after baking.
List of Ingredients with Measurements
Here’s a complete list of the ingredients, along with their precise measurements:
- ½ cup butter, softened
- ¾ cup granulated sugar
- 1 egg
- ¾ Tbsp mint extract
- 3-4 drops green food coloring (optional)
- 1 ½ cup all-purpose flour
- ½ tsp baking soda
- 1 tsp baking powder
- 1 tsp cream of tartar
- ¼ tsp salt
- 1 cup mint chocolate chips
- 1 ½ cup Lucky Charms Marshmallows

Step-by-Step Instructions
Let’s walk through the steps of making these fun and flavorful Lucky Charms Cookies:
First, preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius).
In a mixing bowl, cream together the softened butter and granulated sugar until light and fluffy. This should take about 2-3 minutes.
Add the egg, mint extract, and green food coloring (if using) and mix until the color is fully combined. Scrape down the sides of the bowl as needed.
In a separate bowl, whisk together the flour, baking soda, baking powder, cream of tartar, and salt. This ensures everything is well combined.
Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix.
Once fully combined, fold in the mint chocolate chips and Lucky Charms marshmallows. Use a spatula to ensure even distribution.
Roll the dough into small balls (about 1 tablespoon each) and place them on a cookie sheet, leaving a little space between each cookie.
Bake the cookies for 10 minutes. The edges should be lightly golden brown, and the centers should still be slightly soft.
Let the cookies cool on the cookie sheet for 2 minutes before transferring them to a cooling rack to cool completely.

Troubleshooting
Here are a few common issues you might encounter and how to fix them:
The cookies are too dry: This can happen if you overbake them or if you use too much flour. Make sure to measure the flour accurately and watch the cookies carefully while they bake.
The cookies spread too much: This can happen if the butter is too warm or if you don’t use enough flour. Make sure the butter is softened but not melted, and measure the flour accurately.
The cookies are too flat: Make sure your baking soda and powder are fresh.
The marshmallows melted too much: This can happen if the oven is too hot or if the cookies are baked for too long. Try reducing the oven temperature slightly or baking for a shorter time.
Tips and Variations
Here are a few tips and variations to help you customize this recipe:
For a stronger mint flavor: Use a bit more mint extract, but be careful not to overdo it, as it can become overpowering.
For a different flavor: Try using a different extract, such as vanilla or almond, instead of mint extract.
For a different color: Use different food coloring to match the occasion or your preference.
For added texture: Add some chopped nuts, such as walnuts or pecans, to the dough.
Serving and Pairing Suggestions
These Lucky Charms Cookies are delicious on their own, but they also pair well with a variety of beverages and other treats.
I love serving them with a cold glass of milk or a hot cup of coffee or tea. Classic combinations.
They’re also great with a scoop of vanilla or mint chocolate chip ice cream. Ice cream is always a good idea.
For a festive St. Patrick’s Day spread, arrange the cookies alongside other green treats, such as cupcakes or brownies.
They also make a wonderful homemade gift. Package them in a decorative tin or box and tie with a ribbon.
Nutritional Information
While these cookies are certainly a treat, it’s helpful to be aware of their nutritional content. Enjoy responsibly!
The exact nutritional information will vary depending on the specific ingredients you use. Read labels for accuracy.
These cookies contain butter, sugar, chocolate, and marshmallows, so they are relatively high in calories, fat, and sugar.
However, they also provide a small amount of protein from the egg and a bit of fiber from the flour.
It’s all about balance and enjoying treats in moderation as part of a healthy overall diet. Enjoy occasionally.
