Moist, cakey, and delicious, these pumpkin bars with a thick buttery cream cheese frosting are perfection. They're so easy to make with no mixer required!
Preheat oven to 350°F/180°C. Prepare a 9x13 inch pan by lining it with parchment paper.
In a large bowl whisk together dry ingredients: flour, baking soda, cinnamon, ginger, nutmeg, cloves, and salt.
In a medium bowl, whisk together eggs, granulated sugar and brown sugar until combined. Add melted butter slightly cooled and whisk until combined. Add pumpkin puree and yogurt or sour cream and whisk until combined. Pour the pumpkin mixture into the flour mixture and mix gently just until combined.
Pour batter into parchment-lined pan. Bake for 28-30 minutes until a toothpick inserted into the center of the bars comes out clean. Allow to cool in pan on a wire rack. Frost when completely cooled.
Using a silicone spatula, combine softened cream cheese and softened butter together in a medium bowl until well blended and smooth. Stir in vanilla extract.
Slowly sift in powdered sugar and milk powder, stirring frequently to combine. Stir until smooth and clump-free.
Spread generously over bars using a metal spatula to create an even surface. Refrigerate bars immediately and the frosting will set as it cools.
Keep the bars in the fridge for up to 5 days. Serve them at room temperature so they're soft and moist.
