Mix the wet ingredients: Preheat the oven to 350°F (180°C). Oil a 9-inch square pan and line it with parchment paper, leaving some paper over the edges for easy removal.In a large bowl, whisk 1 can pumpkin puree, 2 large eggs, ¾ cup brown sugar, ½ cup Greek yogurt, ¼ cup vegetable oil, and 2 teaspoons vanilla extract until smooth.
Add the dry ingredients: Add 2 cups all-purpose flour, 3 teaspoons cinnamon, ½ teaspoon ground ginger, ¼ teaspoon ground nutmeg, ¼ teaspoon allspice, 3 teaspoons baking powder, ½ teaspoon baking soda, and ¼ teaspoon salt.Stir gently until just combined. Don’t overmix. The batter should be thick and creamy.
Add raisins and seeds: Fold in ½ cup raisins. Pour the batter into the pan and smooth the top. Sprinkle about ¼ cup pumpkin seeds seeds and, optionally, a little brown sugar.
Bake and cool: Bake at 350°F (180°C) for 30 to 35 minutes, until a toothpick inserted in the center comes out mostly clean with a few moist crumbs.Cool in the pan for 15 minutes, then transfer to a wire rack and cool completely before slicing.

Tips
Use pumpkin puree: Not pumpkin pie filling, which already contains sugar and spices.
Don’t overmix: Stir just until combined to avoid developing too much gluten.
Expect thick batter: Pumpkin and Greek yogurt naturally make it thick and creamy.
Check your baking powder: It should fizz vigorously when added to hot water.
Make it richer: Add ½ cup raisins plus ½ cup chopped walnuts or pecans.
Spread evenly: Smooth the batter into the corners for even baking.
Don’t overbake: Start checking at 30 minutes; a few moist crumbs are perfect.
Cool completely: This helps the crumb set and makes slicing easier.
Add frosting: Cream cheese or vanilla frosting makes it extra special for the holidays.
Storage: Keep covered or in an airtight container in the refrigerator for up to 5 days, or freeze for up to 3 months.
