Step 1: Preheat the Oven

• Preheat your oven to 350°F (175°C) and grease a Bundt pan with cooking spray or butter.

Step 2: Prepare the Dry Ingredients

• In a large mixing bowl, whisk together the flour, baking powder, baking soda, salt, black pepper, garlic powder, and onion powder until well combined.

Step 3: Mix the Wet Ingredients

• In a separate bowl, whisk together the eggs, buttermilk, and vegetable oil until smooth.

Step 4: Combine Wet and Dry Ingredients

• Gradually add the wet ingredients to the dry ingredients, stirring until just combined. Be careful not to overmix; a few lumps are okay.

Step 5: Fold in the Add-Ins

• Gently fold in the shredded cheese, cooked sausage or ham (if using), and chopped spinach or kale until evenly distributed throughout the batter.

Step 6: Pour into the Bundt Pan

• Pour the batter into the prepared Bundt pan, smoothing the top with a spatula.

Step 7: Bake

• Bake in the preheated oven for 45-50 minutes, or until a toothpick inserted into the center comes out clean.

Step 8: Cool and Serve

• Once baked, allow the cake to cool in the pan for about 10 minutes before carefully inverting it onto a wire rack to cool completely. Slice and serve warm.
