Confetti Cake-in-a-Jar Mix

Adults · 15 min · about $5

  1. Whisk the flour, baking powder, and salt in a small mixing bowl until thoroughly combined.
  2. Use a funnel to pour the flour mixture into the bottom of the clean, dry 16 oz jar.
  3. Press the flour layer down firmly with a spoon or a cocktail muddler to create a flat surface.
  4. Pour the granulated sugar over the flour, followed by the rainbow sprinkles as the final top layer.
  5. Seal the lid tightly to prevent moisture from clumping the ingredients.
  6. Cut a 2-inch circle from the cardstock and write the following instructions: 'Mix with 1/2 cup softened butter, 2 eggs, and 1/2 cup milk. Bake at 350°F for 25-30 minutes.'

  3. Write a personal message, memory, or joke inside each corresponding strip.
  4. Roll each strip tightly and tie it with a 4-inch piece of satin ribbon to secure the scroll.
  5. Fill the jar with the finished scrolls, alternating colors for visual balance.
  6. Apply a cardstock label to the front of the jar using double-sided tape, titled 'A Year of Notes for [Name].'

  4. Fill the remaining space at the top with white chocolate chips to keep the layers from shifting.
