Before you start, prepare a 23cm/9-inch springform cake pan by greasing and lining it. Once that's done, preheat your oven to 350F/180C.
In a mixing bowl, combine almonds, coconut, sugar, flour, and salt, then whisk to aerate and eliminate lumps.
In a separate bowl, lightly whisk eggs. Add melted butter, vanilla extract, and lemon zest, and whisk until thoroughly combined. Pour this mixture into the dry ingredients and whisk until well blended.
Transfer half the dough into the cake tin, layer with half the raspberries, and top with the remaining dough and raspberries.
Add flaked almonds, then bake for 50 minutes, checking closely towards the end for a clean skewer test.
After a 30-minute rest, invert the cake out of the tin, discard the parchment, and position it correctly on a serving plate. You can serve it warm with cream or refrigerate it for later.
You can store it in an airtight container or wrap it in aluminum foil, and it will stay fresh for 3 days. Plus, it freezes beautifully for a month.
