Being on maternity leave this year, I am trying to make as many Christmas gifts as I can. This is a really simple thing that I'm doing for my girlfriends.

5/8 cups all-purpose flour
1/2 teaspoon baking powder
1/2 teaspoon salt
1/3 cup unsweetened cocoa powder
5/8 cups white sugar

Layer the ingredients as listed into a 500ml jar. Attach a tag with the following instructions

"Empty jar into a large mixing bowl, and stir to blend. Mix in 3/4 cup melted butter and 4 eggs. Mix thoroughly. Spread batter evenly into greased 8 inch baking pan. Bake for 25 to 30 minutes at 350'. Cool completely in pan before cutting."
