Why You’ll Love This Apple Oat Cake

This oatmeal cake is a great way to start the day. This recipe is flavored with lots of Fall spices and in-season apples. Here are a few more reasons we love this recipe and you will too!

  • Cozy Fall Flavor: This cinnamon apple cake is flavored with applesauce, cinnamon, nutmeg, and cardamom. I love enjoying a slice of it with a cup of tea or a cozy coffee as the weather starts to get a bit chillier.
  • Healthy and Hearty: Made with healthy oats (which we grind into oat flour), this cake is a great way to start the day. You can make it into a healthier dessert with a drizzle of cinnamon icing.
  • Simple & Great for Meal Prep: With only 1 bowl, and 10 minutes of prep time, this cake is easy to prepare on the weekend, so you have a filling breakfast all week long.
  • Perfect for Every Moment: Whether as a snack cake, a dessert after dinner with a scoop of vanilla ice cream, or a slice to accompany your coffee, it fits every occasion.


  • Old-fashioned Oats: The foundation of the cake, giving it a wholesome texture and hearty bite.
  • Warm Spices: A comforting blend of ground cinnamon, nutmeg, and cardamom pair so well with the apples and pecans.
  • Maple Syrup or Agave Nectar: This cake uses natural sweeteners to keep it refined sugar-free.
  • Unsweetened Applesauce: This replaces eggs in the cake (to keep it vegan), provides moisture, and reinforces the apple flavor.
  • Vanilla Extract: A splash for aromatic depth and flavor.
  • Almond Milk: Or your milk of choice, to bring the wet ingredients together.
  • Melted Coconut Oil: Adds a touch of richness and ensures the cake has the perfect moist crumb.
  • Apples: Whether you lean towards a pink lady or a tart granny smith, you can’t have apple cake without fresh apples!
  • Pecans or Walnuts (Optional): For those who love a bit of crunch in their slice.
