Recipe by Chef Kate
From pastry chef Kim Boyce formerly of Campanile, by way of the LA Times. Amazingly good! Use the dark-skinned sweet potatoes commonly referred to as yams. The long cooking time includes the roasting of the sweet potatoes.

The title says it all! I made this as directed but mixed all of the wet ingredients together except the buttermilk and then alternated that with the flour mix. My sweet potatoes may have been a bit too large because I ended up baking them about an hour and they still were a bit too moist in the middle but still very tasty. I did sub Splenda products for the sugars. Mine puffed up really high too! Made for the Please Review tag game.

- vegetable oil, spray for coating the tins

- 1 tablespoon cinnamon
- 1 teaspoon ginger
- 1⁄2 teaspoon allspice

Directions See How It's Made
- Heat the oven to 400 degrees.
- Prick the sweet potatoes with a fork and place on a foil-lined cookie sheet.
- Roast for 1 hour or until they are tender when pierced with a fork and are caramelizing.
- Remove from the oven and allow to cool, then peel and lightly mash with a fork. Set aside.
- Lower the oven temperature to 350 degrees. Lightly spray the muffin tin with vegetable oil.
- Cream the butter and sugars until light and fluffy, about 3 minutes.
- In a medium bowl, sift together the flour, whole-wheat flour, whole-grain pastry flour, baking powder, baking soda, salt, cinnamon, ginger and allspice. In a separate bowl, whisk the buttermilk, yogurt, egg and vanilla together.
- Scrape down the sides of the butter bowl and alternately add the dry and wet ingredients; do not overmix. Gently fold in the sweet potatoes, then the dates.
- Using an ice cream scoop (about one-half cup capacity), scoop the batter into each of 10 prepared muffin cups, about 1 scoop per muffin.
- Bake for 35 to 40 minutes. The muffins will be dark golden brown on the bottom.
