Pumpkin-Orange Muffins

Preheat the oven to 350 degrees F (175 degrees C). Grease two 12-cup muffin trays or line with paper liners.

Sift flour, sugar, baking powder, cinnamon, and salt together in a large bowl. Mix in prunes.

Mix pumpkin, orange juice, milk, eggs, orange zest, and vanilla extract together in a separate bowl. Fold into flour mixture. Add melted butter and mix well.

Divide batter between the prepared muffin cups.

Bake in the preheated oven until a toothpick inserted into the center of a muffin comes out clean, about 20 minutes.

Remove muffins from the oven and place on wire racks to cool, 20 to 30 minutes. Dust with confectioners' sugar.
