Sweet Potato Casserole with Coconut-Macadamia Topping

Ingredients

For the Sweet Potato Filling:
3 1/2 pounds sweet potatoes, peeled and cut into 1-inch chunks
1/2 cup heavy cream
1/3 cup packed brown sugar
1 tablespoon unsalted butter
1 teaspoon vanilla extract
1/4 teaspoon coconut extract
1 egg, lightly beaten
1 teaspoon sea salt

For the Topping:
1/2 cup all purpose flour
1/2 cup sweetened coconut flakes
1/3 cup rolled oats
1/4 cup macadamia nuts
1/4 cup packed brown sugar
1/4 cup cold unsalted butter, cut into small dice

Directions

1. Preheat the oven to 375°F. Lightly oil a 9-inch square-baking dish.
2. Combine the sweet potatoes with enough water to cover by 2-inches in a large saucepan over medium-high heat. Bring to a boil and cook until the potatoes are very tender, 12-15 minutes. Drain and transfer to a large bowl.
3. Meanwhile, combine the cream, sugar, butter, vanilla extract, coconut extract, egg and salt in a bowl. Add mixture to the potatoes and beat with an electric mixer on medium until smooth. Transfer to the prepared baking dish.

For the Topping:

1. combine the flour, coconut flakes, oats, nuts and sugar in a bowl. Add the butter and work it into the flour mixture with your fingers until you can form it into clumps. Sprinkle the mixture over the sweet potatoes.
2. Bake in the center of the oven, covered, for 20 minutes. Uncover the casserole and bake until heated through and the top is browned, about 20-22 minutes longer. Let stand 10 minutes before cutting.
