Bring a taste of summer to your table with this Nectarine and Berry Buckle. Juicy nectarines, blueberries, raspberries, and blackberries are baked into a light, fluffy cake, then topped with a sweet, crunchy cinnamon topping; a dollop of whipped cream adds the perfect finishing touch.
Line a 9x13-inch pan with baking paper and spray with baking spray. Set aside.
To make the topping, combine the flour, brown sugar, cinnamon, and salt in a small bowl. Whisk to blend, then cut in the butter until the mixture is crumbly. Set aside.
For the batter, in a large bowl, cream the butter and 3/4 cup sugar until light and fluffy, about five minutes. Add the eggs one at a time, beating well after each addition. Beat in the vanilla.
In a separate bowl, whisk together the flour, baking powder, and salt. Add this to the creamed mixture alternately with the milk, beating well after each addition. Set aside 3/4 cup of the batter.
Fold the blueberries into the remaining batter.
Spoon the blueberry batter into the prepared baking dish. Arrange the nectarines on top and sprinkle with the remaining tablespoon of sugar. Drop the reserved batter by teaspoonfuls over the nectarines. Sprinkle with the raspberries, blackberries, and prepared topping.
Bake at 350°F for 35 to 40 minutes or until a toothpick inserted in the center comes out clean. Serve warm with whipped cream.
