One bite of these M&M cookies and you'll be transported back to grandma's kitchen. This old-school recipe is super easy to make, but it definitely still holds up as a fan favorite today. A good trick for more candy-filled cookies is to add M&M's to the dough then push extra candies into each dough ball before they're baked.
1 cup shortening
1 cup packed brown sugar
½ cup white sugar
2 eggs
1 ½ teaspoons vanilla extract
2 ½ cups all-purpose flour
1 teaspoon baking soda
1 teaspoon salt
1 ½ cups candy-coated milk chocolate pieces (such as M&M's®)
Preheat the oven to 350 degrees F (175 degrees C).
Beat shortening, brown sugar, white sugar, eggs, and vanilla in a mixing bowl until light and fluffy, 2 to 3 minutes.
Add flour, baking soda, and salt; blend well. Stir in 1/2 of the chocolate candies.
Drop dough by teaspoonfuls onto an ungreased baking sheet. Use remaining candies to decorate dough balls; press down slightly.
Bake in batches in the preheated oven until lightly browned with soft centers, 9 to 11 minutes.
