This is the softest, plushest little pumpkin cake. This lovely little snack cake is slathered with a delicious maple, mascarpone cream cheese frosting dolloped with spiced jammy pumpkin butter. This cake has the lushest texture and is a dream to whip up. The flavors of brown butter and buckwheat paired with the spices heighten the nutty notes on this cake and make this cake just all that more special.
