Ingredients

  • 1 cup oats divided
  • 1 large apple peeled and chopped
  • 3 tablespoons honey or substitute with maple syrup or brown sugar
  • 1 teaspoon vanilla extract
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon baking powder
  • 3 tablespoons yogurt
  • 2 eggs
  • 1 tablespoon butter or coconut oil

Instructions

  • Preheat the oven to 350°F (180°C).
  • Add all ingredients—except 1/4 cup of the oats—into a blender or bowl (if using a hand blender). Blend until smooth.
  • Stir in the remaining 1/4 cup of oats by hand for a bit of texture.
  • Line a small baking pan with parchment paper and pour the mixture in evenly.
  • Bake for 20–30 minutes, or until a toothpick inserted in the center comes out clean.
  • Let the cake cool completely, then slice. Store the slices in an airtight container in the fridge for at least 1 hour before serving. The flavor improves as it chills.

Notes

If you’re out of honey or maple syrup, you can use 3–4 tablespoons of dark brown sugar instead.
Taste the batter before baking to ensure it’s sweet enough for your preference.
A smaller baking pan yields a thicker, more cake-like texture.
