Really Good Christmas Fruitcake

Preheat the oven to 275 degrees F.
Grease four 9×5-inch loaf pans and line the bottoms with parchment paper. Grease the parchment paper.
In a small bowl, toss the candied fruit, the raisins, and the walnuts in 1/2 cup of the flour.
In a large bowl, cream the butter and the sugar until light and fluffy.
Add the eggs, one at a time, to the butter mixture, beating well after each addition.
Gradually beat the remaining flour into the butter mixture.
Fold the fruit mixture into the batter.
Divide the batter between the 4 prepared pans.
Bake until a toothpick inserted in the center comes out clean, about 50-60 minutes.
Allow the cakes to cool in the pans for 10 minutes.
Transfer the cakes to wire racks to cool completely.
Slice and serve.
