Layer the Ingredients: Start with the flour. Spoon it into the jar and level it off. Next, add the baking powder, baking soda, and salt. Make sure to pack them down a bit.

After that, add the brown sugar. Pack it firmly in the jar. Then, layer in the granulated sugar.

Finally, top it all off with the M&M's or chocolate chips. Try to make the layers look pretty!

Seal the Jar: Once all the ingredients are in the jar, put the lid on tightly.

Add a Recipe Note: Print a note that includes the baking instructions. You can attach this to the jar with a ribbon or place it inside the jar before sealing it.

Preheat your oven to 350°F (175°C).

In a large bowl, mix the contents of the jar with softened butter, egg, and vanilla extract.

Combine until mixed well.

Drop spoonfuls of the dough onto a baking sheet lined with parchment paper.

Bake for 10-12 minutes or until the edges look golden.

Let cool and enjoy!
