These soft and fluffy triple berry muffin mix cookies are bright and delicious. With only 4 super easy ingredients, you can whip these up in less than 20 minutes. And, they are easy to customize for the flavor you love.
Preheat the oven to 375 degrees Fahrenheit. Also, grease the cookie sheet with cooking spray or butter if it is not no-stick.
Add 1 egg and ½ cup of softened butter to the mixing bowl.Tip: softened butter should have an indentation left in the center if you press on it. Soften on the counter or on defrost for 20 second intervals in the microwave (without allowing it to start melting).
Beat together the butter and egg on medium-high speed with the mixer. This usually takes about 2 minutes. It will become lighter and fluffier when it is done.
Add in 1 Teaspoon of vanilla and 2 - 6.75 oz packages of muffin mix.
Mix them together on low speed for a minute or two. Everything should be well combined when done.
Use a tablespoon or cookie scoop to measure out large balls of dough about 1.5 tablespoons in size.
Place the balls of dough a few inches apart on the cookie sheet.
Bake at 375 degrees Fahrenheit for 8 - 10 minutes or until the edges of the cookies are light brown and firm.
Notes
Tips & Variations
Mix-ins - add extra flavor by putting in ½ a cup of chopped nuts, candy pieces, dried or fresh fruit or chocolate chips.
Glaze or icing - sweeten them up by drizzling the tops of the cookies with a glaze or icing.
Different flavor muffin mixes - change up the flavor by using your favorite flavor of muffin mix.
No overcooking - make sure to keep them soft by taking them out of the oven when the edges are firm and centers are still soft.
Adjust for package size - we used 13 oz of muffin mix. If you want to use more or less muffin mix, or have different size packages just scale the butter and eggs accordingly. Add an additional egg after about 20 oz of muffin mix. And add or subtract about 1 tablespoon of butter per every 2 - 3 oz.
