Blueberry Zucchini Oat Snack Cake or breakfast cake, after dinner with a cup of tea cake…pretty much an anytime type of cake!  This cake is both gluten-free and vegan!

I’m reluctant to let go of summer ingredients and move on to fall flavors.  While the fall is extremely beautiful in the North East, I’m always going to be a warm weather girl.  I try to embrace the crisp air and changing colors, but my enthusiasm never lasts too long!  Come November I will be longing for summer days filled with dips in the ponds, fresh fruit, locally grown vegetables and the beach.

With the last of the zucchini and the blueberries I had stashed in the freezer, I came up with a gluten-free and vegan cake perfect for snacking!  Oats, flax, zucchini, berries and a crumple topping make for a wholesome old-fashioned cake. I used coconut sugar, which has a slightly sweet flavor.  If you do not have coconut sugar feel free to substitute with regular sugar, just note it will make for a sweeter cake.  I make my own oat flour in a vitamix, but you can always use store-bought oat flour.
