Toss grapes with remaining Tbsp flour, then fold into batter.

Divide batter among muffin cups. Sprinkle with remaining 2 Tbsp granulated sugar. Bake until golden and springy to the touch, 18 to 20 minutes. Cool in pan 5 minutes, then loosen with a knife and remove. Cool to warm, 5 to 10 minutes more. 
                                         
                                    
                                
                             
                        
                    
                    Cooks’ note: Cakes can be baked in 12 (1/3- to 1/2-cup) muffin cups. Baking time will be slightly shorter, 16 to 18 minutes.
