In a small bowl, combine the filling ingredients & set aside.
Plachinda Pastry
Preheat oven to 350 F.
In a medium bowl, combine flour, sugar, baking powder & salt. Whisk together eggs, milk & oil; add dry ingredients, working into a soft, stiff dough.
Turn onto a lightly floured piece of parchment paper. Roll dough into a 14 x 14-inch square; spread pumpkin filling down the center & halfway out to the sides — about 1/4-inch thickness.
Fold the outside third of the dough over filling, repeating with the last third; pinch to seal. Leaving plachinda on paper, transfer to a baking sheet.
Bake for about 35-40 minutes or until golden brown. Slice & serve warm.
