PrintEmail Appearing three times in the Harry Potter series, Hagrid's cakes were as hard are rocks and certainly nothing to write home about. Fortunately the only thing rock-like about these cakes is the name. They are great served with tea or if you're in the mood for a buttery cookie that isn't overly sweet. Ingredients 2 cups all-purpose flour1/2 cup granulated sugar1 teaspoon baking powder1/2 teaspoon cinnamon1/4 teaspoon salt1 stick (8 tablespoons) cold butter, cut into chunks1 large egg1/3 cup whole milk1 cup raisins Instructions Preheat the oven to 350F and grease and flour a large cookie sheet. Combine the flour, sugar, baking powder, cinnamon, and salt in a large mixing bowl. With your fingertips, rub the butter into the dry ingredients until the mixture reaches the consistency of wet sand. Beat the egg together with the milk and pour it into the flour-butter mixture. Fold it together using a spatula to form a stiff dough. Fold in the raisins. Drop dough by rounded tablespoonfuls 2 inches apart on the prepared cookie sheet. Bake for 25 minutes or until the bottoms are golden, rotating the pan midway through baking. —Recipe reprinted with permission from The Unofficial Harry Potter Cookbook by Dinah Bucholz (Adams Media, 2010).
