Preheat oven to 350. Line 2 standard muffin tins with paper liners. Sift together flours, baking powder, and salt.
Beat butter and granulated sugar with a mixer on medium speed until pale and fluffy, about 3 minutes. Beat in eggs, one at a time, and vanilla. Reduce speed to low, and add the flour mixture in 3 additions, alternating with the milk, beginning and ending with the flour mixture; beat until combined after each addition. Fold in huckleberries by hand.
Divide batter among cups. Bake, rotating halfway through, until golden brown, about 25 minutes. Let cool.
Beat cream and confectioners' sugar until firm peaks form. Dollop cupcakes with whipped cream, garnish with berries, and dust with confectioners' sugar.
I am so excited to try this... as a native Montanan I am always looking for recipes to use huckleberries in... if you have never tasted a huckleberry you really need to take a trip to my beautiful state... your taste-buds will thank you!
