Now that’s my kind of canning. 
One of my all time favorite cookie recipes was an “in a jar” recipe:
Oatmeal-Chip Cookies in a Jar:
1 c. all purpose flour, 1/2 c. brown sugar, packed, 1/2 c. sugar, 1/2 t. baking soda, 1/2 t. baking powder, 1/2 t. salt, 1 t. cinnamon, 1-1/4 c. quick-cooking oats, 1 c. any flavor chips
Layer flour, brown sugar and sugar in a quart jar, packing down lightly after each addition. Combine baking soda, baking powder, salt and cinnamon in a small bowl and add to jar. place oats in jar. fill remainder with flavoed chip. attach tag with instructions.
Pour jar contents into a large bowl; mix 1/2 c. oil, one egg and 1 t. vanilla. form into one inch balls and arrange on ungreased baking sheet. Bake 350* for 10 to 15 minutes. makes 3 doz.
Soooo good!!
