Ingredient Breakdown

This cake keeps things simple and wholesome with a short list of pantry staples:

• Rolled oats or oat flour: The base of the cake, providing fiber and a hearty texture.
• Apples: Grated or finely chopped, they add natural sweetness and moisture.
• Eggs or flax eggs: For binding and structure; flax eggs make it vegan-friendly.
• Greek yogurt or applesauce: Adds creaminess and moisture without extra fat.
• Natural sweeteners: Choose from honey, maple syrup, or mashed banana for a refined sugar-free option.
• Baking powder: Helps the cake rise and stay fluffy.
• Spices: Cinnamon and nutmeg bring warmth and depth of flavor.
• Optional add-ins: Walnuts for crunch, raisins for extra sweetness, and vanilla extract for aroma.

Tip: Use tart apples like Granny Smith to balance the sweetness and enhance the flavor complexity.

This combination of ingredients creates a cake that’s not only delicious but also nourishing. The oats and apples work together to provide fiber and texture, while the natural sweeteners and yogurt or applesauce keep it moist and flavorful. It’s a flexible recipe that welcomes substitutions, making it easy to adapt to your taste or dietary needs.

Step-by-Step Instructions

Follow these simple steps to bake your own Healthy Oatmeal Apple Cake:

1. Preheat your oven to 350°F (175°C). Grease an 8×8-inch baking pan or line it with parchment paper for easy removal.
2. Prepare the wet ingredients: In a large mixing bowl, whisk together 2 eggs (or flax eggs), ½ cup Greek yogurt or applesauce, and ¼ to ⅓ cup of your preferred natural sweetener (honey, maple syrup, or mashed banana).
3. Add the dry ingredients: Stir in 1½ cups of rolled oats or oat flour, 1½ teaspoons baking powder, 1 teaspoon cinnamon, and ¼ teaspoon nutmeg. Mix until well combined.
4. Fold in the apples: Gently stir in 1½ cups of grated or finely chopped apples. If using, add ¼ cup chopped walnuts, ¼ cup raisins, and 1 teaspoon vanilla extract.
5. Pour the batter into the prepared pan and spread evenly.
6. Bake for 35–40 minutes, or until the top is golden and a toothpick inserted in the center comes out clean.
7. Cool completely in the pan before slicing into squares.

Tips for success:

• Avoid a soggy texture by squeezing excess moisture from grated apples before adding them.
• For a moist crumb, don’t overbake—check at the 35-minute mark.
• Let it rest after baking to allow the oats to fully absorb moisture and set the cake.

This cake stores well in the fridge and tastes even better the next day!
