Preheat oven to 350°. In a large bowl, beat together melted butter, sugar, yogurt, eggs, and extracts. Mix until smooth and creamy. Slowly add salt, baking powder, and flour. Once everything is combined, fold in blueberries. Spray one 9x5 bread pan with non-stick spray and pour batter into pan. Top batter with sliced almonds and evenly sprinkle extra sugar over top. Place in oven on middle rack for about 45 minutes or until knife comes out clean when placed in the center. Let cool and serve. Enjoy warm or cold!
