Since starting work I've developed a bit of a morning routine. I'm not usually hungry at 7.30am on a weekday morning but my stomach is growling by 9.30am when I'm at work. So this is my breakfast time - and it always consists of two slices of smooth peanut butter on toast, and usually a mug of hot chocolate on the side.
I don't think I will ever be sick of the peanut butter and chocolate combination. I love the sweetness of the chocolate against the nutty, slightly salty flavour of the peanut butter and I thought it would make the perfect macaron flavour. What makes these macarons even better is that you don't even have to make a filling for the macaron shells. I just simply heated up some peanut butter so that it was easy to spread and sandwiched it between two macaron shells. It's best to leave these to sit in the fridge for a night or two since the peanut butter doesn't have too much liquid in it so the filling will take a bit longer to soften the shells and for the flavour to permeate into the macaron shells.
You could of course go ahead and make a peanut butter buttercream but I think the saltiness of the peanut butter tends to get lost with the addition of sugar so I think just using plain peanut butter for the filling is perfect. Of course, you can always use crunchy peanut butter but I'm a smooth peanut butter kind of girl :)
And since it's now acceptable to have cake for breakfast (muffins and banana bread are really just an excuse to eat cake for brekky, am I right?), I don't see why you couldn't have chocolate peanut butter macarons for breakfast. After all, breakfast is the most important meal of the day and you might as well have something tasty heh =D
(Note: Penguin says Feed Me does not condone the eating of macarons for breakfast - eat healthy, high protein, low GI breakfasts people!)
