Gluten-Free Blueberry Buttermilk Breakfast Cake

Must Try Recipes

If you spend any amount of time on Pinterest, then you’ve probably seen this Buttermilk Blueberry Breakfast Cake pinned about a million times in the past couple of weeks or so.  Well, I wanted to get in on the fun but was shocked when a Google search for a gluten-free buttermilk coffee or breakfast cake turned up empty.  Luckily I was in the mood to do some recipe tinkering.

Using Alexandra’s recipe as my starting point, I did some gluten-free tweaking, crossed my fingers and hoped for the best.  Luckily it turned out to be a total success.

It’s light and moist with a delicate, crispy sugar crust.  And since it has blueberries in it, it becomes a totally legit breakfast option.  Although that’s coming from somebody who has no qualms about eating a brownie for breakfast on occasion, so you should probably refrain from taking any nutrition advice from me, OK?
