1. Preheat your oven to 375°F and line a baking sheet with parchment paper.
2. In a large bowl, whisk together the flour, baking powder, and salt. Add the cold butter cubes and mix until the mixture resembles coarse crumbs.
3. Pour in the buttermilk and stir until a dough forms. Turn the dough onto a floured surface and knead gently.
4. Roll the dough out to about 1/4-inch thickness and cut out circles using a biscuit cutter.
5. In a skillet, cook the sausage over medium heat until browned. Remove the sausage, leaving the drippings, and set aside.
6. Add 2 tablespoons of flour to the drippings, stirring until golden brown. Gradually whisk in the milk, cooking until thickened.
7. Season the gravy with salt, pepper, and cayenne if using. Stir the cooked sausage back into the gravy.
8. Place a spoonful of sausage gravy in the center of each dough circle, fold over, and seal the edges.
9. Place the bombs on the prepared baking sheet and bake for 15-18 minutes or until golden brown.

These biscuits remind me of the mornings spent with my abuela, making everything from scratch, and they carry the same love and warmth.
