Make this simple blueberry cake recipe! This blueberry cake is tender and delicious, loaded with blueberries, and not too sweet. It’s naturally sweetened and whole grain as written, too (check recipe notes for more flour options). Recipe yields one 9-inch round cake, enough for 8 slices.
Recipe adapted from my Healthy Blueberry Muffins.
*How to make buttermilk: Combine 2 teaspoons vinegar with 2/3 cup milk of choice (any milk will do). Let the mixture rest for 5 to 10 minutes before adding it to the other liquid ingredients.
Flour options: All-purpose flour and gluten-free all-purpose blends also work well here. I bet that you could use 2 1/2 cups oat flour instead, but haven’t tried to be sure.
Change it up: Know that the cinnamon and turbinado sugar are technically optional. You could try this cake with raspberries or sliced strawberries in place of the blueberries. Instead of buttermilk, you could use 1 cup plain Greek yogurt or sour cream. For lemony cake, whisk the zest of 1 medium lemon (about ½ teaspoon), preferably organic, into the liquid ingredients.
Make it dairy free: Make your own buttermilk from your non-dairy milk of choice. Replace the butter with 1/3 cup melted coconut oil or mildly flavored extra-virgin olive oil, like California Olive Ranch.
Make it vegan: Follow dairy-free guidance above and substitute flax eggs for the regular eggs.
