The Best Apples for Baking

The type of apple you choose can make a big difference. We recommend using firm, crisp apples that hold their shape during baking. Honeycrisp, Gala, or Granny Smith are excellent choices that offer a wonderful balance of sweet and tart flavors.

Flour and Oats

We use a combination of whole wheat flour and rolled oats. The whole wheat flour adds a nutty flavor and extra nutrients, while the rolled oats provide a wonderful chewy texture. Avoid steel-cut oats, as they won’t soften enough during baking.

Natural Sweeteners & Fats

Pure maple syrup provides a warm, complex sweetness that pairs beautifully with cinnamon and apple. For fat, melted coconut oil and unsweetened applesauce work together to create an exceptionally moist cake without needing butter.

How to Make The Best Healthy Oatmeal Apple Cake

Making this cake is as easy as mixing and baking. Follow these simple steps for a perfect result every time.

  1. Preheat and Prep: Start by preheating your oven to 350°F (175°C). Lightly grease and flour a 9-inch round cake pan to prevent sticking.
  2. Combine Dry Ingredients: In a large mixing bowl, whisk together the whole wheat flour, rolled oats, baking soda, baking powder, ground cinnamon, nutmeg, and salt. Mixing the dry ingredients first ensures the leavening agents are evenly distributed.
  3. Combine Wet Ingredients: In a separate, medium-sized bowl, whisk the unsweetened applesauce, maple syrup, eggs, melted coconut oil, and vanilla extract until everything is smooth and well combined.
  4. Mix Batter: Pour the wet ingredients into the bowl with the dry ingredients. Stir gently with a spatula until just combined. It’s important not to overmix, as this can lead to a tough cake.
  5. Fold in Apples: Gently fold your diced apples into the batter.
  6. Bake to Perfection: Pour the batter into your prepared cake pan and use the spatula to spread it into an even layer. Bake for 35-40 minutes. You’ll know it’s done when a toothpick inserted into the center comes out clean.
  7. Cool Completely: Let the cake cool in the pan for about 10 minutes. Then, carefully invert it onto a wire rack to cool completely before slicing and serving.

Tips for the Perfect Apple Oat Cake

  • Don’t Overmix: Mix the batter until the ingredients are just combined. Overmixing develops the gluten in the flour, which can result in a dense, tough cake.
  • Dice Apples Uniformly: Cut your apples into small, uniform pieces (about 1/2-inch cubes) to ensure they cook through evenly and are distributed well in every slice.
  • Room Temperature Ingredients: For a smoother, more uniform batter, use room temperature eggs and applesauce. This helps the ingredients emulsify better.

Delicious Variations & Substitutions

This recipe is wonderfully versatile. Here are a few ideas to make it your own:

  • Make it Gluten-Free: Swap the whole wheat flour for a 1-to-1 gluten-free all-purpose baking blend.
  • Add a Crunch: Fold in 1/2 cup of chopped walnuts or pecans along with the apples for a delightful crunch.
  • Warm Spice Boost: Add 1/4 teaspoon of ground ginger or allspice to the dry ingredients to enhance the warm spice flavor. If you’re a fan of unique spice blends, check out this Huli Huli Chicken for inspiration on flavor combinations.

Storing Your Oatmeal Apple Cake

This cake stores beautifully. Keep it in an airtight container at room temperature for up to 3 days. If you need to store it longer, it will last in the refrigerator for up to a week. For a quick and hearty meal idea that also stores well, consider these ground beef burrito bowls.
