Make sure the jar
is full to the top. Cover the lid with a 7 1/2-inch circle
of fabric tied with ribbon or raffia. Finish with a tag that
includes liquid ingredients and baking instructions as follows:
Prepare Your Sand-Art Brownies: In a large mixing bowl,
combine the contents of the quart jar with 3 well-beaten eggs,
vegetable oil, and 1 teaspoon vanilla extract. Stir well
to combine all ingredients.
Pour Batter into a well-greased
9-inch by 13-inch cake pan and bake in a pre-heated 350-F
degree oven for 30 to 35 minutes.
Cool, cut and enjoy!
