Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
85 g oat flour
2 medium apples (about 300 g total), peeled and grated
1 ripe banana (about 120 g), mashed
2 large eggs
7 g baking powder
1/8 teaspoon salt
Directions
Preheat your oven to 180°C (350°F). Grease a small 8-inch (20 cm) round cake pan or line it with parchment paper.
Peel and grate the apples using the fine side of a grater. If they are very juicy, lightly squeeze out excess liquid, but keep some moisture for a soft cake.
In a large mixing bowl, mash the ripe banana with a fork until smooth.
Add the eggs to the mashed banana and whisk until fully combined.
Stir in the grated apples and mix well.
In a separate bowl, combine the oat flour, baking powder, and salt.
Gradually fold the dry ingredients into the wet mixture. Stir gently until no dry streaks remain. Do not overmix.
Pour the batter into the prepared cake pan and smooth the top.
Bake for 30–40 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cake to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.

FAQs
Can I use regular flour instead of oat flour?
