Preheat your oven to 425°F (220°C). This high temperature ensures that your biscuits rise beautifully and develop a golden-brown crust.
In a large mixing bowl, whisk together the White Lily Self-rising flour, sugar, black pepper, and cayenne pepper until thoroughly mixed.
Make a well in the center of the dry ingredients and add in the mayonnaise and whole milk. Gently fold the mixture until just combined.
Fold in the shredded sharp cheddar cheese and diced pimentos.
Using a spoon or a cookie scoop, drop spoonfuls of the biscuit batter onto a baking sheet lined with parchment paper.
Drizzle or brush the tops of the biscuits with melted butter before placing them in the oven.
Bake the biscuits in the preheated oven for 15-18 minutes or until they are golden brown and a toothpick inserted in the center comes out clean.
Once baked, remove the biscuits from the oven and let them cool slightly on the baking sheet before transferring them to a wire rack.
