Using a mason jar funnel, pour the flour mixture into the bottom of the 32 ounce size mason jar.

You can use a tart tamper to help you spread the flour out evenly.

Then add the brown sugar. Use the tart tamper again to spread evenly.

Add the granulated sugar.

Finally add the chocolate chips, Reese's Pieces candies, and the Reese's Mini Peanut Butter Cups.

Affix the printed label to the lid of the jar. Seal the jar tightly with the lid and ring.
