Top Reasons To Make It
- It’s naturally gluten-free, using wholesome oat flour for a tender crumb.
- You only need one bowl to make it. Less cleanup is always a win.
- The cozy cinnamon and sweet apple flavor is a classic everyone loves.
- It’s incredibly moist and stays that way for days.
- This cake is the perfect easy gluten free cake for birthdays, potlucks, or just because.
Ingredients
- 2 cups oat flour: The base of our gluten free cake, giving it a lovely, hearty texture.
- 2 tsp baking powder: Helps our cake rise and become light and fluffy.
- 1 tsp ground cinnamon: For that essential warm, cozy spice flavor.
- 1/2 tsp fine sea salt: Balances all the sweetness and enhances the other flavors.
- 2 large eggs: Bind everything together and add richness.
- 1/2 cup pure maple syrup: A natural sweetener that adds a deep, caramel-like note.
- 1/3 cup melted coconut oil: Makes the cake incredibly moist. You can use avocado oil too.
- 2 tsp pure vanilla extract: The secret to a wonderful aroma and flavor.
- 1/2 cup unsweetened applesauce: Keeps the cake super moist and adds apple flavor.
- 1 medium apple, peeled and finely chopped: For little pockets of sweet, baked apple throughout.
Instructions
- Preheat your oven to 350°F (175°C). Grease an 8-inch round or square cake pan and line it with parchment paper for easy removal.
- In a large bowl, whisk the oat flour, baking powder, cinnamon, and salt together until they’re well combined.
- In a separate medium bowl, whisk the eggs, maple syrup, melted coconut oil, vanilla extract, and applesauce until the mixture is smooth and uniform.
- Pour the wet ingredients into the dry ingredients. Gently fold everything together with a spatula until you no longer see streaks of flour. Be careful not to overmix. Fold in the finely chopped apple.
- Pour the batter into your prepared pan and smooth the top with your spatula. Bake for 30-35 minutes. You’ll know it’s done when the top is golden, the edges pull away from the pan, and a toothpick inserted into the center comes out clean.
- Let the cake cool in the pan for about 15 minutes before transferring it to a wire rack to cool completely. This patience helps it set perfectly.
Variations & Substitutions
- Dairy-Free & Vegan: For a dairy free gluten free cake, use a flax egg (1 tbsp ground flaxseed + 3 tbsp water per egg, let sit 5 mins) instead of regular eggs.
- Nutty Twist: Fold in 1/2 cup of chopped walnuts or pecans for a delightful crunch.
- Chocolate Lover’s: Stir in 1/2 cup of dairy-free chocolate chips to turn this into a fantastic gluten free chocolate cake variation.
- Spice It Up: Add a pinch of nutmeg or cardamom along with the cinnamon for more warmth.
- Sugar Swap: You can use an equal amount of honey instead of maple syrup if you prefer.
Tips For Success
- Make sure your oat flour is certified gluten-free if you have a sensitivity, as oats can sometimes be processed in facilities with wheat.
- Don’t overmix the batter! Just fold until combined for the most tender crumb.
- For an extra pretty finish, slice a few thin apple pieces and arrange them on top of the batter before baking.
- Let the cake cool almost completely before slicing. It’s a little fragile when warm but sets up beautifully.
- And if you don’t have store-bought oat flour, you can make your own by blending gluten-free old-fashioned oats in a blender until fine. So easy.
Gluten Free Baking Notes
Gluten-free baking can feel tricky, but oat flour is a wonderfully forgiving ingredient. It doesn’t need any complicated blends or gums to work its magic. The key is to measure your flour correctly—fluff it up in the bag, spoon it into your measuring cup, and level it off. Don’t pack it down. This ensures you get the perfect amount for a moist gluten free cake every time. And remember, gluten-free cakes are often more tender and delicate than their wheat-based cousins, which is a beautiful thing.
Storage & Reheating
Store any leftover cake in an airtight container at room temperature for up to 2 days. For longer storage, keep it in the refrigerator for up to 5 days. This cake also freezes beautifully! Wrap the whole cake or individual slices tightly in plastic wrap and then in foil. Freeze for up to 3 months. Thaw overnight in the fridge. For that just-baked warmth, pop a slice in the microwave for 15-20 seconds. So good.
Frequently Asked Questions
- Can I make this into cupcakes? Absolutely! This batter makes wonderful cupcakes. Line a muffin tin, fill cups 2/3 full, and bake for 18-22 minutes at the same temperature.
- What’s the best apple to use? I love using sweeter, baking apples like Fuji or Gala because they soften beautifully and don’t need much added sugar.
- Is this considered a flourless cake recipe? While it uses oat flour, which is gluten-free, it is not technically flourless. For a truly flourless option, you’d want a nut-based cake.
- Can I use a different pan? A 9-inch round pan will work, but your cake will be a bit thinner, so start checking for doneness around 25 minutes.
- This is my first homemade gluten free cake. Any advice? You’ve picked a great one to start with! Just follow the instructions, trust the process, and get ready to enjoy a delicious, cozy win.
