Start by preheating your oven to 375°F (190°C).

In a mixing bowl, cream together the butter, white sugar, brown sugar, and vanilla using a mixer.

Add the eggs one at a time and continue beating until the mixture is light and fluffy-almost like the texture of whipped marshmallow.

In a separate bowl, combine the flour, baking soda, and salt.

Using a low speed setting, gradually add the dry ingredients to the wet ingredients to avoid spilling flour.

Fold in the M&M’s and chocolate chips; mix just until combined.

Use a small cookie scoop to drop cookie dough onto prepared pan, keeping dough balls intact (do NOT flatten).

Bake for 9 minutes before removing from the oven.

While still warm, press a Hershey’s Kiss onto each cookie top.

Allow cookies to cool on a wire rack; eat warm or after completely cooled.
