Happy National Doughnut Day! I almost waited until Sunday to share this recipe in memory of the Science Sundays posts I used to share but when I found out today was doughnut day I couldn’t resist spilling the beans/blueberries a bit early.
Two months ago I was discussing how to make blueberry doughnuts taste more blueberry-ish with the owner of a local doughnut shop, Rose Dough Donuts, and discovered that the answer is ground coriander! Evidently coriander enhances blueberries and I will try to briefly explain how and why I used it in my baked blueberry doughnuts today.
Terpenes are naturally occurring aromatic compounds produced by many plants for their smell, taste, and color. Linalool is one type of terpene found in both (you guessed it) blueberries and coriander so if you add just a little coriander, preferably freshly ground, it tricks our mind into thinking there is more blueberry flavor in there.

I did also add a bit of lemon zest because citrus is also helpful in boosting those bloobs. I wasn’t taking any chances even though I used very fresh ripe blueberries that I picked up from a Farmers Market the very same day I made these baked blueberry doughnuts. Stumbling upon that market might be the real reason these blueberry doughnuts were born.
While baked doughnuts are never going to hold a candle to fried doughnuts they certainly win points in the cleanup category as I hate dealing with frying food and already have doughnut pans in my arsenal. It is a special day that I willingly deal with a vat of hot oil. Since I bet I am not alone in this sentiment, I present to you my baked blueberry doughnuts! Glazed with even more blueberry puree just incase the coriander and lemon wasn’t already doing enough work. I am not messing around when it comes to my blueberry doughnuts as they are one of my absolute favorites.
You should also try my baked strawberry-ginger glazed doughnuts that I dream about as well.
