I've always used this site:
This was a favorite when I made them. I gave cans of pumpkin along with the jar, so that people wouldn't need to buy them:
Pumpkin Cranberry Bread Mix in a Jar
1 1/2 cups all-purpose flour
1 1/2 teaspoons pumpkin pie spice
1/2 teaspoon baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
1/3 cup brown sugar, packed
1 cup granulated sugar
1/2 cup chopped pecans
3/4 cup dried cranberries
In a large bowl, combine the flour, pumpkin pie spice, baking powder, baking soda and salt, stirring until well blended. Place mixture into a 1-quart jar. Pack down this layer. Add the brown sugar to the jar, firmly packing down. Layer the granulated sugar on top of the brown sugar, firmly packing. Layer the pecans and then the dried cranberries into the jar. Adjust cap. Makes base for one recipe of Pumpkin Cranberry Bread.
Attach the following instructions to the jar:
Pumpkin Cranberry Bread:
1 jar pumpkin cranberry bread mix
1 cup canned pumpkin puree
1/2 cup vegetable oil
Heat oven to 350 degrees F. Grease and flour (or use spray) two 7 1/2 x 3 3/4 x 2 1/4 inch loaf pans (or 4 small loaf pans).
In a large bowl, combine the pumpkin, oil and eggs, stirring until well blended; set aside.
Place contents of jar into a medium bowl; mix until well blended and brown sugar is no longer clumped. Add flour mixture into the pumpkin mixture, stirring until well blended. Divide batter evenly between the prepared pans. Bake for 40-50 minutes (30 to 35 minutes for the small pans), or until inserted wooden pick comes out clean and tops of loaves spring back when pressed.
The same year I did these I did split pea soup in a jar too. That was a hit as well.
