Step 1: Preheat the Oven and Prepare the Pan
Preheat the oven to 350°F (175°C) and line a 9-inch loaf pan with parchment. Whisk eggs and sugar until smooth, then mix in yogurt, olive oil, and pumpkin puree.
Step 2: Add The Dry Ingredients
Add flour, baking powder, salt, cinnamon, cardamom, and walnuts. Gently fold with a spatula until just combined and lump-free.
Step 5: Cool the Cake
After baking, cool the cake in the pan for 10 minutes. Lift it out with the parchment paper and transfer to a wire rack to cool completely before slicing.
Pour the batter into the pan, smooth the top, and bake for 45–60 minutes. Start checking at 45 minutes; it's done when a toothpick comes out clean or with a few crumbs.
