Ingredients
Here’s what you’ll need to create this comforting Apple Oat Cake:
- 2 cups (180 g) rolled oats (old-fashioned, not instant)
- 2 large apples, peeled, cored, and roughly chopped (about 300-350 g or 2 cups chopped)
- 2 large eggs
- ½ cup (120 ml) milk (dairy or non-dairy, such as almond or oat milk)
- ¼ cup (60 ml) maple syrup or honey
- 2 tablespoons (30 g) melted coconut oil or unsalted butter
- 1 teaspoon baking powder
- 1 teaspoon ground cinnamon
- ½ teaspoon vanilla extract
- ¼ teaspoon salt
- Optional: ¼ cup (30 g) chopped walnuts or pecans, extra apple slices for topping
Ingredient Notes
- Rolled Oats: Use old-fashioned rolled oats for the best texture and structure. Instant or quick oats have a different consistency and may result in a gummier cake.
- Apples: Firm, sweet-tart apples like Honeycrisp, Gala, Fuji, or Granny Smith work wonderfully. Avoid overly soft or mealy apple varieties.
- Sweetener: Maple syrup and honey both provide natural sweetness and moisture. You can adjust the amount slightly to your preference.
- Milk: Any milk you have on hand will work, dairy or non-dairy.
- Coconut Oil/Butter: Adds richness and moisture. If using unsalted butter, make sure it’s melted and slightly cooled.
Equipment You’ll Need
- Blender or food processor
- 8×8 inch (20×20 cm) baking dish
- Mixing bowl (if not using blender for final mix)
- Measuring cups and spoons
- Parchment paper (optional, for easy removal)
How to Make Apple Oat Cake
Follow these simple steps to bake your wholesome Apple Oat Cake:
- Prepare Your Pan & Preheat Oven: Preheat your oven to 350°F (175°C). Lightly grease an 8×8 inch (20×20 cm) baking dish or line it with parchment paper, leaving an overhang on two sides for easy lifting.
- Make Oat Flour: Place the rolled oats into your blender. Blend on high speed until the oats are finely ground into a flour-like consistency. Transfer about 1 cup of the oat flour to a separate mixing bowl and set aside.
- Blend Wet Ingredients & Apples: To the blender with the remaining oat flour, add the chopped apples, eggs, milk, maple syrup (or honey), melted coconut oil (or butter), vanilla extract, and salt. Blend until the mixture is mostly smooth. Some small chunks of apple are fine and add to the texture.
- Combine & Mix: Pour the wet apple-oat mixture from the blender into the mixing bowl with the reserved oat flour. Add the baking powder and ground cinnamon. Stir gently with a spatula until just combined. Be careful not to overmix. If using, fold in the chopped walnuts or pecans at this stage.
- Pour & Bake: Pour the batter into your prepared baking dish, spreading it evenly. If desired, arrange a few thin apple slices on top for decoration.
- Bake Until Golden: Bake for 30-35 minutes, or until the cake is golden brown around the edges and a toothpick inserted into the center comes out clean.
- Cool & Serve: Let the cake cool in the pan on a wire rack for at least 15-20 minutes before slicing and serving. This helps it set properly.
Pro Tips for the Best Results
- Don’t Overmix: Once you combine the wet and dry ingredients, mix just until no streaks of flour remain. Overmixing can develop the gluten in the oats and make the cake tough.
- Choose the Right Apples: Using apples that hold their shape well and offer a good balance of sweet and tart will elevate the cake’s flavor and texture.
- Let it Cool: While tempting to dive in immediately, allowing the cake to cool slightly helps it firm up and makes for cleaner slices.
- Adjust Sweetness to Taste: If your apples are very sweet, you might reduce the maple syrup slightly. If you prefer a sweeter cake, you can add an extra tablespoon.
- Parchment Paper is Your Friend: Lining the pan with parchment paper not only prevents sticking but also makes lifting the entire cake out for slicing incredibly easy.
Common Mistakes to Avoid
- Using Instant Oats: Instant or quick oats are processed differently and will absorb liquid too quickly, leading to a gummy or overly dense cake. Stick to old-fashioned rolled oats.
- Underbaking: An underbaked oat cake can be soggy in the center. Ensure the toothpick test comes out clean and the edges are golden brown.
- Not Prepping the Pan: Even with a non-stick pan, greasing or lining with parchment paper is crucial to prevent sticking and ensure easy removal.
- Blender Overload: If your blender isn’t powerful enough, blend the oats into flour in two batches to avoid straining the motor and ensure a fine consistency.
Variations & Substitutions
- Other Fruits: Replace apples with ripe pears, peaches, or even a mix of berries for a different twist.
- Spice It Up: Add ¼ teaspoon of nutmeg, allspice, or ground ginger alongside the cinnamon for a more complex spice profile.
- Add-ins: Stir in ¼ cup of dried cranberries, raisins, or mini chocolate chips with the nuts (or instead of) for extra flavor and texture.
- Gluten-Free: This recipe is naturally gluten-free if you use certified gluten-free rolled oats.
- Vegan Version: Substitute the eggs with 2 “flax eggs” (2 tbsp ground flaxseed mixed with 6 tbsp water, let sit for 5 minutes), use plant-based milk, and ensure your coconut oil is truly plant-based.
Serving Suggestions
This Apple Oat Cake is delightful on its own, but here are some ways to make it even more special:
- Warm & Simple: Enjoy a slice warm, perhaps with a dusting of powdered sugar.
- Creamy Toppings: Serve with a dollop of Greek yogurt, a scoop of vanilla ice cream, or a drizzle of warm custard.
- For Breakfast: Pair it with your morning coffee or tea, or crumble it over a bowl of yogurt with fresh fruit.
- Extra Sweetness: A light drizzle of extra maple syrup or a dollop of apple butter makes a lovely addition.
Storage & Reheating
- Countertop: Store leftover cake in an airtight container at room temperature for up to 2 days.
- Refrigerator: For longer storage, keep it in an airtight container in the refrigerator for up to 5 days.
- Freezer: This cake freezes beautifully! Once completely cooled, slice the cake into individual portions. Wrap each slice tightly in plastic wrap, then place them in a freezer-safe bag or container. Freeze for up to 2-3 months.
- Reheating: Thaw frozen slices in the refrigerator overnight. Reheat individual slices in the microwave for 30-60 seconds, or in a toaster oven at 300°F (150°C) for 5-10 minutes until warmed through.
