Ingredients

• 1 cup unsalted butter
• 1 cup packed brown sugar
• 1 cup white sugar
• 4 large eggs
• 2 teaspoons vanilla extract
• 1.5 cups all-purpose flour
• 1 teaspoon baking powder
• 0.5 teaspoons salt
• 2 cups peeled and finely shredded yam
• 1 cup confectioners' sugar
• 2 tablespoons salted butter or margarine
• 2 tablespoons milk

Instructions

1. 1 Preheat the oven to 350 degrees F (175 degrees C). Grease a 9x13-inch baking dish.
2. 2 Beat 1 cup unsalted butter, brown sugar, and white sugar together in a large bowl until smooth. Beat in eggs, one at a time, beating well after each addition. Stir in vanilla. Combine flour, baking powder, and salt in a separate bowl; stir into butter mixture until blended. Fold in yam. Spread batter into the prepared baking dish.
3. 3 Bake in the preheated oven until a toothpick inserted in center comes out clean, about 30 minutes.
4. 4 Meanwhile, combine confectioners' sugar, 2 tablespoons salted butter, and milk until smooth. Spread over brownies while still warm, they will absorb some of the glaze.
