Yield: 1 quart-size mason jar + 1 batch of brownies

Ingredients

For the Mason Jar Assembly:

  • 1 cup all-purpose flour
  • 1/3 cup unsweetened cocoa powder
  • 1 cup granulated sugar
  • 1/2 cup packed brown sugar
  • 1/2 cup chocolate chips (semi-sweet or milk)
  • 1/2 cup chopped walnuts or pecans (optional)
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon salt

For the Recipient to Add (Not Included in Jar):

  • 2 large eggs
  • 1/2 cup melted butter (or vegetable oil)
  • 1 teaspoon vanilla extract

Directions

Assembling the Mason Jar Mix

  1. Layer the dry ingredients into a clean, dry 1-quart mason jar in the following order:
    • Flour
    • Cocoa powder
    • Granulated sugar
    • Brown sugar
    • Baking powder and salt
    • Chocolate chips
    • Nuts (if using)
  2. Pack each layer firmly using the back of a spoon to prevent shifting. This keeps the layers clean and visually appealing.
  3. Seal the jar tightly with a lid. Attach a tag with the baking instructions for the recipient.

Instructions for Baking the Brownies (Include on Gift Tag):

  1. Preheat oven to 350°F (175°C). Grease an 8x8-inch baking pan or line it with parchment.
  2. In a mixing bowl, whisk together 2 eggs, melted butter, and vanilla.
  3. Pour the entire contents of the mason jar into the bowl. Stir until just combined—overmixing can make brownies tough.
  4. Spread batter evenly in the prepared pan.
  5. Bake for 22–28 minutes, or until the center is set and a toothpick inserted comes out with moist crumbs (but not wet batter).
  6. Cool before cutting into squares. For fudgier brownies, slightly underbake; for cakier brownies, bake a minute or two longer.
