The "Berry-Best" Muffins from "Stir-Ups" the Junior League Cookbook from Enid, Oklahoma...
1 cup butter
2 cups sugar
4 eggs
2 teaspoons vanilla
4 cups flour
1 cup milk
4 teaspoons baking powder
1 teaspoon salt
4-5 1/2 cups fresh or frozen blueberries, raspberries, blackberries or cranberries* (or combination of any of these)
*If using frozen fruit, partially thaw and combine with 1/4 cup flour. Fresh berries should be rinsed, drained and well dusted with flour before folding into batter.
Cream butter and sugar in large mixing bowl. Add eggs one at a time, and vanilla. Blend thoroughly. Combine flour, baking powder and salt. Alternately add flour mixture and milk to first mixture. (The batter will be very thick.) Blend well. Fold in berries. Grease muffin tins. (Because batter will need to expand over the rim, it is best to grease or oil muffin tin beyond the rims of cups. You may use paper liners, but top of tin should still be oiled to allow for overage.) So that muffins will take on a mushroom shape, heap batter above rim of muffin tins. This will produce a beautiful shape. Sprinkle generously with sugar and bake in a preheated 425 degree oven for 10 minutes. After 10 minutes of baking, turn oven temperature down to 375 degrees and bake an additional 15 minutes until muffins are done in center and a rich golden brown on top.
These are a really good "cake like" muffin which tastes great with the "tart" berries!
