I am making m&m cookies.

Conclusion:

When you have your butter make sure you keep the butter out so it can soften so it's easier to mix. I didn't leave the butter out so it was very hard for me to mix. (let the butter soften until it is room temperature or soft)

Supplies

1/2 cup unsalted butter softened but still cool
1/2 cup granulated sugar
1/3 cup brown sugar, lightly packed make sure it's fresh and soft
2 eggs
2 teaspoons pure vanilla extract
1 1/2 cups M&M's
1 1/2 cups all-purpose flour
1 teaspoon baking powder
1/2 teaspoon baking soda
1/4 teaspoon salt

Step 1: Beat the Sugar

Make the dough by beating butter with granulated sugar and brown sugar. The brown sugar will impart moisture, sweetness and chew. Beat these ingredients for 2 minutes, until light and fluffy.

Step 2: Adding Ingredients

Add 2 eggs and plenty of vanilla extract – 2 whole teaspoons and then mix them together.

Step 3: Add Dry Ingredients

Add the dry ingredients: flour, leaveners, and salt.

Step 4: Mix

Now your mix-ins get added together. Then stir in the M&M’s.

Step 5: Bake Them

Scoop the cookie dough into balls. Press some additional M&M’s on those dough balls if you want and then bake. Preheat oven to 350°F.

Step 6: Take Them Out

Pull the baking sheets from the oven when the cookies are set around the edges, (if you have baking sheets) but still under baked in the center. And then you're done!
