This cardamom and lemon cake recipe is perfect for those who love the combination of citrus and spice. Using a food processor, blend together flour, sugar, baking powder, and ground cardamom. In a separate bowl, whisk together eggs, lemon juice, and melted butter. Combine the wet and dry ingredients and pour the batter into a greased cake pan. Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean. Serve with a drizzle of lemon glaze and a sprinkle of ground cardamom.
