This is by far my favorite blueberry recipe:
Blueberry pound cake
1 pound butter
2 cups sugar
8 eggs
4 C flour
4 C blueberries
Preheat oven to 300*
Butter 2 loaf pans Cream butter and sugar mix in eggs one at a time Fold in all but 3 T flour toss blueberries with the 3 T flour, fold into batter and place in 2 loaf pans Bake for one hour and 30 to 50 min depending on pan size cool and remove from pan let sit overnight slice and serve. The Best I have used this one for years and we love it!!!
