Cranberry Christmas Cake

3 eggs
2 cups sugar
3/4 cup butter, softened
1 teaspoon vanilla
2 cups flour
12 oz fresh cranberries

Preheat oven to 350

Beat sugar and eggs with a mixer until slightly thickened and light in color, about 5-7 minutes.  The mixture should almost double in size and form a ribbon when you lofe the beaters out of the bowl.  (The eggs work as the leavening agent, so do not skip beating the eggs and sugar together.)  Add butter and vanilla, mix 2 more minutes.

Stir in the flour until just combined.  Add cranberries and stir to mix.

Spread in a buttered 9x13 pan.  Bake for 40-50 minutes or until very lightly browned and a toothpick inserted near the middle comes out clean.  Let cool completely before cutting.
