These are more like little coffeecakes parading as muffins. An amazing buttermilk and vanilla batter is home to toffee chips and the whole thing is anointed with a butter-pecan streusel. Lock these up at night! This is a good time to also investigate muffin scoops at a restaurant supply store. A number 16 or 14 is a good size for commercial style and size muffins. If you want those muffin 'caps' or tops, you really have to consider investing in a great big ice-cream scoop. You can also use the scoop to make muffin tops - just scoop and deposit on a parchment paper lined baking sheet and bake until muffins test done when gently pressed.
