5Blueberries used to taste like blueberries , nut muffin used to taste like nut muffin. Eggnog for the nutmeg tweaks the nuttyness of the muffin and makes it more fancy. Devon cream and frosting makes a great frosting base and cheapens it back up again so it's not to pretentious. I threw some apricot in to jam up the blueberry. Cookie Crumble add some dap and make the muffin more heavy. I also love how it effects blueberries and makes them more sharp and sugary tasting.
