Pre-heat the oven to 175°C. Ground the almonds in a food processor or high speed blender. Align a small round baking dish (26cm diameter) with baking paper.
Combine all dry ingredients in a large bowl.
Mash a banana with a fork. Add it to the oat milk mix and whisk until a smooth liquid forms.
Pour the wet ingredients over the dry ingredients and whisk well until combined. Save the sparkling water for last and only quickly combine it with the batter, so the carbonation won't get out.
Peel the apples, cut them it into quarters and carefully remove the cores. Gently slice the apple quarters without cutting them through. Pour the batter into the baking dish. Carefully push the apple quarters on top of the batter. Sprinkle the batter with the almond slices.
Bake for 45 - 50 minutes. Place aluminum foil or a baking tray on top of the cake for the last 10 minutes to prevent the top from burning.
Remove the cake from the oven and let sit for at least 20 minutes.
Sprinkle with some powdered xylit (I cut out some stars to make it look pretty) and enjoy!
