1. Preheat and Prepare:

2. Begin by preheating your oven to 350°F (175°C). Generously grease and flour a standard 9×5 inch loaf pan. This step is crucial to prevent the cheesy loaf from sticking. Alternatively, you can line the pan with parchment paper, leaving an overhang on the two long sides to easily lift the loaf out later.

3. Combine Dry Ingredients:

4. In a large mixing bowl, add the all-purpose baking mix, 1 cup of the shredded cheddar cheese (reserving the other ½ cup for the topping), the garlic powder, onion powder, smoked paprika, and cayenne pepper (if using). Whisk these ingredients together until they are evenly distributed. This ensures that every bite of the loaf is packed with flavor.

5. Combine Wet Ingredients:

6. In a separate smaller bowl or measuring cup, whisk together the whole milk and the lightly beaten egg until they are fully combined.

7. Mix the Batter:

8. Pour the wet milk and egg mixture into the large bowl with the dry ingredients. Using a spatula or a wooden spoon, gently fold the ingredients together. Be very careful not to overmix! Mix only until the flour is just moistened and the ingredients are combined. The batter will be thick and a bit lumpy, which is exactly what you want for a tender, biscuit-like texture. Overmixing develops the gluten and will result in a tough, dense loaf.

9. Assemble the Loaf:

10. Spoon the batter into your prepared loaf pan. Use your spatula to gently spread it into an even layer, making sure it reaches the corners of the pan. Sprinkle the remaining ½ cup of shredded cheddar cheese evenly over the top of the batter. This will create a beautiful, golden, and crispy cheese crust as it bakes.

11. Bake to Perfection:

12. Place the loaf pan on the center rack of your preheated oven. Bake for 40 to 50 minutes. The loaf is done when it is a deep golden brown on top and a wooden skewer or toothpick inserted into the center comes out clean or with a few moist crumbs attached (but no wet batter).

13. Prepare the Garlic Butter Topping:

14. While the loaf is in its final 5 minutes of baking, prepare the iconic topping. In a small, microwave-safe bowl, melt the ¼ cup of unsalted butter. Once melted, stir in the dried parsley, garlic powder, and the pinch of salt. Mix well to combine.

15. Apply the Topping:

16. As soon as you remove the loaf from the oven, immediately brush the garlic butter topping all over the hot surface. Be generous and make sure to cover the entire top and let some drip down the sides. The heat from the loaf will help it absorb all of that delicious buttery goodness.

17. Cool and Serve:

18. Let the cheese biscuit loaf cool in the pan for at least 10-15 minutes. This allows it to set up, making it easier to slice. After the initial cooling, you can use the parchment paper overhangs to lift it out of the pan and transfer it to a wire rack to cool further. For the best experience, serve the loaf warm.
