Preheat oven to 350F. Line standard muffin tins with paper liners. Whisk together the flour, corn grits, baking powder and ground black pepper and sift; set aside.

Cream the butter and sugar. Add the eggs; stir until well mixed. Add the yogurt and stir until smooth.

Add the flour mixture to the liquid mixture and use a rubber spatula to mix until smooth.

Divide the batter evenly among the lined cups, filling each to 30% full. Add the chunks of blue cheese, then cover with the rest of the dough.

Bake for 20 (+6) min, rotating the tins halfway through. Transfer tins to wire racks to cool completely before removing the muffins.
