Topping
½cupbrown sugar
¼cupflour
½cupchopped pecans
3tablespoonbuttermelted
1 ½ cupsmini marshmallows
Instructions
Preheat the oven to 350 F. Spray an 8x8 baking pan with cooking spray.
In a large bowl, combine the canned sweet potatoes, brown sugar, salt, beaten eggs, melted butter, cinnamon, and vanilla extract. As an optional step, you can also mix in up to 2 tablespoon of flour to help thicken the mixture. Canned sweet potatoes are sometimes thinner than fresh ones.
Spread the mix into the baking pan. Bake the casserole uncovered for 35-40 minutes until it's started to set up a bit and then remove from the oven.
Crumble Topping
Make the topping while the casserole is baking. In a small bowl, combine the crumble topping ingredients including the brown sugar, flour, chopped pecans, and melted butter.
You're going to alternate layers of mashmallows and crumble topping. Top the casserole with half of the marshmallows, then sprinkle half the streusel over the marshmallows. Top with the other half of the marshmallows and sprinkle the remaining pecan crumble over the top.
Place the sweet potato casserole back into the oven for 8-12+ minutes, until the topping is bubbly and golden brown. You don't want the marshmallows to melt! If you want your marshmallows a darker color, pop them under the broiler for 1 minute. Let rest for 10 minutes before serving. Enjoy!
Notes
We used unsweetened pureed sweet potatoes for this recipe. Adjust the recipe if you're using the following:
Canned yams: These come sweetened and aren't pureed. You'll need 3 cups of pureed drained yams. Drain the liquid, otherwise they'll be too much in the recipe then mash them with a fork. Since canned yams are sweetened, we recommend cutting the sweetener in half.
Fresh pureed sweet potatoes: You'll need 3 cups of peeled, boiled, and mashed sweet potatoes (cook about 4 medium-sized sweet potatoes). Canned sweet potatoes have more liquid than fresh, so add ¼-1/2 cup of milk to the recipe.
It's easy to omit the marshmallows if you don't want to use them! We've made it both ways over the years.
