Rhubarb and custard muffins

Based on a recipe on Fresh. Make muffin dough as usual and add finely chopped rhubarb. Then, when you go to put the mixture into muffin cups, put a large tablespoon of dough mixture, then a dollop of custard, and then another large tablespoon of dough mixture. Sprinkle additional rhubarb pieces on top. Bake for 20 minutes or so at 200C.

'Interesting'. I really liked the rhubarb pieces in the muffin, but the muffin mixture used milk and together with the additional custard I felt that the final muffin was too milky. I have yet to find a basic muffin mix I am happy with.
