Step 1: Preheat your oven to 375 degrees Fahrenheit. Grease a 9-inch round cake pan with butter or cooking spray and set aside.

Step 2: In a large mixing bowl, combine the flour, baking powder, salt, and black pepper. Whisk together until well combined.

Step 3: In a separate mixing bowl, beat the eggs until they are light and frothy. Add the milk, olive oil, Parmesan cheese, parsley, and chives. Mix well until the ingredients are well combined.

Step 4: Add the wet ingredients to the dry ingredients and mix until the batter is smooth and well combined.

Step 5: Fold in the chopped asparagus and mix until the asparagus is evenly distributed throughout the batter.

Step 6: Pour the batter into the prepared cake pan and smooth out the top with a spatula.

Step 7: Bake the cake in the preheated oven for 40-45 minutes, or until a toothpick inserted into the center of the cake comes out clean.

Step 8: Remove the cake from the oven and let it cool for 10-15 minutes before removing it from the pan.

Step 9: Serve the asparagus cake warm or at room temperature. Enjoy!
