Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper or lightly grease it.

In a large mixing bowl, whisk together the flour, baking powder, sugar, and salt.

Add the cold cubed butter to the flour mixture. Use a pastry blender or your fingers to work the butter into the flour until the mixture resembles coarse crumbs.

Gradually add the milk to the mixture, stirring until the dough comes together. Be careful not to overmix.

Fold in the crumbled bacon and shredded cheddar cheese until evenly distributed throughout the dough.

Turn the dough out onto a lightly floured surface and pat it into a rectangle about 1 inch thick.

Use a biscuit cutter or a glass to cut out rounds from the dough. Re-form the scraps into a rectangle to cut out additional biscuits.

Take each biscuit round and slightly flatten it in your hand. Place a small amount of additional cheese (and bacon if desired) in the center, then fold the dough around the filling and seal it. Gently reshape it into a biscuit shape if needed. This step ensures each biscuit is stuffed with cheesy goodness.

Place the biscuits on the prepared baking sheet, ensuring they are not touching.

Bake for 12-15 minutes, or until the biscuits are golden brown on top.

Optional: Brush the tops of the biscuits with additional melted butter immediately after taking them out of the oven for extra flavor and a soft crust.

Allow the biscuits to cool slightly on the baking sheet before serving warm.
