Preheat oven to 350°F (175°C).
Now gather all your ingredients together and prepare them in the right amount. That makes baking so much easier and you're less likely to forget anything.
Chop white chocolate and mix with raspberries and 1 teaspoon maple syrup. I use my food processor for that, but you can chop the chocolate with a knife and mash the raspberries with a fork. Then set mixture aside.
Mash the bananas in the food processor. You don't need to clean it before. You can also use a fork for mashing.
Whisk mashed bananas, 60 ml maple syrup, plant oil and plant milk, then combine flour, baking soda, baking powder, salt and vanilla powder in a separate bowl and mix well. Then combine both quickly.
Pour half of the cake dough into a lightly greased form (I used a 24 cm/ 9 inch bundt cake form), then add the raspberry mixture, then the other half of the cake dough.
Gently twist a fork through the batter, marble cake style and bake for about 45 minutes.
Then I usually switch the oven off and leave the cake in there for another 5-10 minutes, so there's not such a temperature difference when taking the cake out.
To toast the sliced almonds, I just put them in a dry pan and toast them for a few minutes. They burn easily, so you want keep an eye on them and keep stirring.
After the cake cooled off, grate remaining white chocolate over the cake, then a little powdered sugar, and decorate with toasted almonds and fresh raspberries.
