Combine flour, sugar, baking powder, baking soda, and salt in bowl.

Use whisk to combine well.

Carefully add dry mix to jar. I like to use a canning funnel for less mess.

Use a ladle to pack ingredients into jar.

Add sprinkles or other decorations on top, if desired.

Attach lid and label to jar.

You can also add a cookie cutter, if desired.

Pour mixture from jar to large bowl. Cream one cup of butter, softened.

Add in 2 eggs and one teaspoon of vanilla extract.

Combine wet and dry ingredients.

Chill prepared dough for one hour.

Roll out to 1/4 inch and cut into desired shapes.

Bake in 350 degree oven for 10-12 minutes, until lightly browned.

Bake for 10 to 12 minutes in the preheated oven, until edges begin to brown.

You can decorate them with sugar before baking or frost after baking.
