1/2 cup unsalted butter at room temperature, plus extra for buttering pan
1-1/3 cups granulated sugar
2 large eggs
2-1/2 cups all-purpose flour, plus extra for dusting pan
1 tsp. baking powder
1 tsp. baking soda
1/4 tsp. kosher salt
1-3/4 cups diced mango (fresh or thawed from frozen)
1/4 cup buttermilk
1 tsp. almond extract
1 tsp. vanilla extract
Confectioners' sugar for dusting (optional)
Berries for serving (optional)
Directions:
1Preheat the oven to 350°F.
2Grease a 9x13-inch baking pan with butter and dust with flour.
3In a stand mixer fitted with the paddle attachment, beat the butter on medium speed until soft, about 2 minutes.
4Add the granulated sugar and continue to beat until well mixed and creamy, about another 5 minutes.
5One at a time, beat in the eggs on medium speed until completely smooth and creamy, about 2 minutes.
6In a large bowl, combine the all-purpose flour, baking powder, baking soda and salt.
7Put the diced mango, buttermilk, and extracts in a blender, and puree until completely smooth.
8In four additions, gradually beat the mango puree and the dry ingredients into the butter mixture, alternating wet and dry ingredients. Mix until completely combined.
9Scrape the batter into the greased and dusted baking pan and place in the oven.
10Bake for 30 minutes, or until the cake is golden brown on top, springy to the touch, and a wooden toothpick comes out dry when inserted.
11Remove from the oven and let cool. Turn the cake out upside down onto a board, and then flip right side up onto a platter.
12Dust liberally with confectioners’ sugar before serving, and garnish with berries of your choice.
