Energy-Efficient Cookies

We can’t claim to have invented no-bake cookies, but we couldn’t resist sharing this classic recipe, which is perfectly in the spirit of this newsletter’s theme. These cookies are delicious, easy to make, and require only a brief flirtation with the stove top (no oven use required).

Recipe yields around 30–32 cookies.

½ cup sliced butter pieces
2 cups granulated sugar
½ cup milk
¼ cup unsweetened cocoa powder
½ cup creamy peanut butter
1 teaspoon vanilla extract
3 cups quick-cooking oats


  1. Measure out ingredients, line two large baking sheets with parchment paper and set aside.
  2. Put the butter, sugar, milk, and unsweetened cocoa powder in a saucepan and heat over medium heat. Stir often until the butter is melted and the ingredients are combined. Then, bring the mixture to a boil and allow to boil for 60 seconds while stirring occasionally.
  3. Remove from heat, stir in the peanut butter and vanilla until fully combined. Add the oats to the mix, stir until oats are coated and everything is well combined.
  4. Use a two-tablespoon cookie scoop to measure out spoonfuls of the mixture on the prepared baking sheets. Allow to cool for 20-30 minutes and serve!
