1 1/2Cpureed sweet potatoesI used the kind from the can. Try to get the kind without corn syrup if you can. They have a really good one at Trader Joe's.
4large eggs
1Cvegetable oil
1Capple cider
Unbaked crumb topping1/2 C butter, 1 C flour, and 1 C brown sugar mixed by hand until crumbly
In a large bowl, combine the sugar, sweet potatoes, and eggs. Beat until smooth.
Mix in the oil and apple cider.
Slowly add the flour mixture and mix until fully incorporated.
Fill cupcake liners halfway.
Add a thin layer of the unbaked crumb topping on top of the batter. Bake the remainder of the crumb topping according to the directions in the crumb topping post.
Because you'll need to use unbaked crumb topping in the cupcakes themselves and baked crumb topping to garnish the cupcakes, I suggest that you prepare all of the unbaked topping you'll need at once and I have written the instructions accordingly.
