Preheat oven to 350 degrees. Peel sweet potatoes and slice each one into 10 round slices, approx 1/2 to 1 inch thick. Lay flat on a parchment lined baking sheet. Make sure they have space in between each one. Spray with coconut oil spray before adding praline topping.
Melt butter in microwave safe bowl. Add pecans, sugar and vanilla and stir well. Top praline mixture evenly among sweet potato slices. Bake for 30 min, or until sweet potatoes are soft when pressed with a fork, but not over cooked. Serve warm or cold and enjoy!
These sweet potatoes are not over the top sweet, so if you want them to be more like a dessert, brush with honey before adding praline topping.
