Description

Healthy Oatmeal Apple Cake is a simple, nourishing cake that doubles as breakfast or dessert — tender, slightly sweet, and full of oatmeal comfort.


Ingredients

Scale
  • 1 cup rolled oats
  • 1 tsp ground cinnamon
  • ½ tsp baking soda
  • ½ tsp baking powder
  • 1 medium apple, peeled and chopped into small pieces
  • 3 tbsp honey (or maple syrup)
  • 1 tsp pure vanilla extract
  • 3 tbsp plain yogurt (dairy or plant-based)
  • 2 large eggs (or flax eggs for vegan)
  • 1 tbsp unsalted butter or coconut oil, melted


Instructions

  1. Preheat your oven to 350°F (180°C) and line a small baking pan with parchment. This keeps removal clean and stress-free. Always use parchment for easy release.
  2. Put everything except 1/4 cup of the oats into a blender or food processor. Blitz until the mixture becomes smooth and homogenous. Don’t overblend — you want a cake batter, not glue.
  3. Transfer the batter to a bowl and gently fold in the reserved 1/4 cup of whole oats. Then stir in the chopped apple so the fruit stays in little pockets through the cake. This adds texture and those lovely apple bursts.
  4. Pour the batter into the prepared pan and level the top with a spatula. Slide it into the oven and bake for about 20–30 minutes. Start checking at 20 minutes: insert a toothpick in the center — if it comes out clean or with a few moist crumbs, it’s done. Do not overbake; you want it moist.
  5. Let the cake cool in the pan for 10–15 minutes, then lift it out using the parchment and transfer to a wire rack to finish cooling completely. Cooling fully makes slicing cleaner and prevents crumbling.

Notes

  • Storage & serving ideas
    • Store cooled slices in an airtight container in the fridge for up to 4 days.
    • Freeze single slices for easy breakfasts — wrap tightly and freeze up to 3 months.
    • Serve warm with a spoonful of Greek yogurt or a drizzle of extra honey. Want dessert vibes? Add a small scoop of vanilla ice cream (treat yourself).
  • Tips for success
    • Reserve some oats to keep texture — don’t blend every last one.
    • Use a mix of apple textures if you like — sweet Gala for softness, Granny Smith for a little tang.
    • Swap yogurt for applesauce if you want a dairy-free version with comparable moistness.
    • Pulse, don’t pulverize when using a blender — aim for smooth batter with tiny oat flecks.
    • Measure carefully — simple ratios matter more with oat-based cakes.
