Ingredients
Scale
- For the Apple Oat Cake Batter:
- 2 cups (180 g) old-fashioned rolled oats, finely blended into flour (approximately 1 3/4 cups oat flour)
- 2 medium ripe sweet apples (Fuji, Gala, or Honeycrisp), peeled, cored, and finely chopped (approximately 2 cups)
- 3 large eggs, room temperature
- 1/3 cup (80 ml) pure maple syrup or raw honey
- 1 tsp baking powder
- 1 tsp ground cinnamon
- 1 tsp pure vanilla extract
- Optional Add-Ins:
- 1/4 cup (30 g) chopped walnuts or pecans
- 1/4 cup (40 g) raisins or dried cranberries
Instructions
- Preheat Oven and Prepare Cake Pan: Preheat your oven to 350°F (175°C). Line the bottom of an 8-inch round cake pan with parchment paper and lightly grease the sides to help prevent the cake from sticking during baking.
- Blend Rolled Oats into Fine Oat Flour: Place the 2 cups (180 g) of old-fashioned rolled oats into a high-speed blender or food processor. Blend continuously for 1–2 minutes until the oats are completely transformed into a fine, flour-like powder. You should have approximately 1 3/4 cups of homemade oat flour. Transfer the finely ground oats to a large mixing bowl.
- Prepare Apple Inclusions: Peel and core the 2 medium ripe sweet apples, such as Fuji, Gala, or Honeycrisp. Finely chop them into uniform 1/4-inch cubes, yielding approximately 2 cups of diced apples. Keeping the apple pieces small ensures they soften evenly during baking and distribute throughout the delicate oat cake crumb. Set aside.
- Mix Wet Ingredients: In a separate medium mixing bowl, whisk together the 3 room-temperature eggs, 1/3 cup (80 ml) of pure maple syrup or raw honey, and 1 teaspoon of pure vanilla extract until the mixture is smooth, uniform, and well combined.
- Combine Dry Oat Base: Add 1 teaspoon of baking powder and 1 teaspoon of ground cinnamon to the large bowl containing the finely blended oat flour. Whisk thoroughly until the leavening and cinnamon are evenly distributed throughout the oat flour.
- Form Batter and Fold in Apples: Pour the prepared egg, maple syrup, and vanilla mixture into the dry oat flour base. Stir gently with a rubber spatula until a thick, cohesive cake batter forms. Carefully fold in the finely chopped apples. If desired, add 1/4 cup (30 g) of chopped walnuts or pecans and 1/4 cup (40 g) of raisins or dried cranberries. Mix gently until the fruit and optional add-ins are evenly distributed throughout the batter.
- Rest Batter and Transfer to Pan: Allow the apple oatmeal cake batter to rest at room temperature for 5 minutes so the oat fiber can absorb some of the moisture and thicken naturally. Pour the batter into the prepared 8-inch round cake pan and smooth the surface evenly with a rubber spatula.
- Bake Until Golden and Set: Place the cake pan in the preheated oven and bake at 350°F (175°C) for 35–40 minutes, or until the top is beautifully golden brown and the center is fully set. Insert a toothpick into the center of the cake; it should come out clean or with just a few moist crumbs attached. Avoid overbaking to preserve the naturally moist apple and oat texture.
- Cool, Slice, and Serve: Remove the baked apple oatmeal cake from the oven and allow it to cool in the pan for 15 minutes so its delicate structure can firm up. Carefully transfer the cake to a wire cooling rack and let it cool further as desired. Slice into 8 equal portions and serve slightly warm or at room temperature for a deliciously soft, cinnamon-scented homemade treat!
Notes
- Blend Oats Very Finely: Process the old-fashioned rolled oats until they reach a fine, flour-like powder consistency. Coarse oat particles can make the finished cake dense and crumbly rather than soft and cohesive, so take the full 1–2 minutes to blend them thoroughly.
- Chop Apples Small: Cut the apples into tiny, uniform 1/4-inch cubes. Large apple chunks can weigh down the delicate wheat-free cake structure and prevent the crumb from setting evenly. Small pieces distribute beautifully throughout the cake and soften during baking.
- Do Not Overbake: Because this apple oatmeal cake contains no butter or oil, excessive baking can evaporate the natural moisture from the fruit and dry out the oat crumb. Remove the cake from the oven as soon as the center is set and a toothpick comes out clean or with a few moist crumbs.
