Preheat oven to 375 degrees F. Combine the whole wheat and all-purpose flours, sugar, baking powder, and salt in a bowl. Using a pastry blender cut in butter to resemble coarse crumbs. Whisk together the pumpkin and egg; add to flour mixture and stir until dough comes together.

On a floured surface knead dough by gently folding and pressing until it just holds together. Pat dough out to 3/4-inch thickness. Using a floured 2-inch biscuit cutter cut out shortcakes; reroll scraps as necessary. Place shortcakes 1 inch apart on an ungreased baking sheet. Bake for 12 to 15 minutes or until golden. Cool on baking sheet for 5 minutes. Serve warm shortcakes split and filled with Blueberry Filling and Blueberry Sauce (see Steps 3 and 4 below).

Blueberry Filling: Combine whipping cream and sugar in a chilled mixing bowl. Beat with an electric mixer on medium speed until soft peaks form (tips curl). Fold together whipped cream and VOSKOS® Nonfat Blueberry Greek Yogurt. Serve immediately or chill up to 5 hours.

Fresh Blueberry Sauce: Combine blueberries and sugar in a food processor and pulse until a chunky sauce forms. Transfer blueberry mixture to a small pan. Simmer for 2 minutes. Serve warm.
