The secret of the biscuit part? You wanna know?
It's easy, but not something everyone can do.
First put your muffin mixture in your muffin cups and insert into preheated oven.
Then leave for a while.
And then leave longer.
And finally leave too long.
There you go, - biscuit muffins. :)
Although - getting through that crunchy outside was totally worth in. Inside was soft and yummy (at least when eaten right after I took them out of the oven (benefit of being the muffin maker)).
