Seriously amazing I don't think I'll ever make muffins again! I actually forgot to add the blueberries (I used fresh) and I had to add the berries after I already formed my puck and then chill the dough. It was surprisingly easy to mix the berries in and I was worried they'd mush and mess things up. I also decided not to make the icing since this was a treat for my small kiddos and I wanted a less sticky mess. Incredibly delicious and I made them easily while wearing a newborn. Oh I also just blended everything in my food processor, didn't feel like mixing the butter by hand.
