Consider this:

Is there a better way to entice your friends to participate in some Earth Day activities than to offer cookies after the event? This project will need some assistance from an adult but the reward is about three dozen delicious Earth cookies.


  • Cookie sheets
  • Mixing bowls
  • Mixer (hand or standing)
  • Green food coloring
  • Blue food coloring
  • Spatulas
  • Wax or parchment paper
  • Glass


  • (2) Cups (4 sticks) sweet cream salted butter (softened)
  • (2) Cups granulated sugar
  • (2) Large eggs
  • (2) Tablespoons vanilla extract
  • (4) Teaspoons baking powder
  • (6) cups all-purpose flour
  • Milk (optional)
  • Heat oven to 350 degrees.
  • Add four sticks of butter to a mixing bowl. The butter should be soft, not warm or the dough will be dry – let it sit on the counter for about an hour to soften.
  • Cream the butter and sugar until it is completely combined – medium speed for about 3-4 minutes.
  • Add two tablespoons of vanilla to the creamed mixture.
  • Add two eggs to the mixture.
  • Mix again until the dough is light and fluffy (3 – 4 minutes).

In a separate bowl add:

  • 4 teaspoons baking powder
  • 6 cups of flour
  • Whisk the dry ingredients to evenly distribute
  • Add two cups of the dry mixture to the butter/sugar mix at a time – mixing the whole time.
  • Continue adding the flour mix until all is incorporated into the dough.
  • Careful to not over mix, and if the dough seems very dry and crumbly add a teaspoon of milk at a time until consistency is what you’d like.
  • On a sheet of wax or parchment paper divide the dough into two equal balls.
  • Add one ball back into the mixing bowl.
  • Add green food coloring and mix.
  • Continue adding coloring until desired shade.
  • Remove green dough, place on wax or parchment paper, and repeat with second dough ball.
  • With the second dough ball, add blue food coloring and mix.
  • Continue adding coloring until dough is desired shade.
  • Remove blue dough and place on wax or parchment paper.
  • Take pieces of the blue and green dough and assemble a small ball (smaller than a walnut, golf ball or ping pong ball) and place on a cookie sheet.
  • Use the bottom of a glass to smash the dough balls down a bit, not flat but like a disk.
  • Bake cookies for about 6 – 10 minutes. Be careful to not over bake. Every oven is different so watch the first batch carefully.
  • Let the cookies cool and enjoy.
  • Americans consume over 2 billion cookies a year, that’s about 300 cookies for each person!
  • Half the cookies baked in America are chocolate chip.
  • The first cookies were reported in the 7th century BCE (or AD) in Persia.
