Instructions

  • Preheat the oven to 350°F (175°C). Lightly grease a 10¼-inch springform pan, or line a standard cake pan with parchment paper.
  • In a small bowl, mix the blueberries, coconut sugar, lemon juice, and melted coconut oil (or applesauce). Spread this mixture evenly over the bottom of the prepared pan.
    3 cups fresh or frozen blueberries, 3 tablespoons coconut sugar or brown sugar, 1 ½ tablespoons lemon juice, 1 ½ tablespoons melted coconut oil or unsweetened applesauce
  • In a separate small bowl, mix the ground flaxseed with water to make flax eggs. Let it sit for 5 minutes to thicken.
    1 ½ tablespoons ground flaxseed, 4 tablespoons water
  • In a large mixing bowl, whisk together the white whole wheat flour, oat flour, baking powder, cinnamon (if using), and salt.
    1 ½ cups white whole wheat flour, ¾ cup oat flour, 3 teaspoons baking powder, ¾ teaspoon cinnamon, ½ teaspoon salt
  • In another bowl, combine the almond milk, maple syrup, applesauce, melted coconut oil (if using), vanilla extract, lemon zest (if using), and the thickened flax mixture.

  • Pour the wet ingredients into the dry ingredients. Stir gently until just combined. Do not overmix. A few small lumps are okay.
  • Pour the batter evenly over the blueberry mixture in the pan. Smooth the top with a spatula.
  • Bake for 35 to 45 minutes, or until a toothpick inserted in the center comes out clean.
  • Let the cake cool in the pan for 10 to 15 minutes. Then carefully flip it onto a serving plate so the blueberry topping is on top.
  • Slice, serve, and enjoy!

Notes

  • You can use fresh or frozen blueberries. No need to thaw if using frozen.
  • For an oil-free version, replace all coconut oil with unsweetened applesauce.
  • To make your own oat flour, blend rolled oats in a high-speed blender until fine.
  • Regular whole wheat or all-purpose flour can be used instead of white whole wheat.
  • Let the cake cool slightly before flipping to avoid breaking the topping.
