Preheat your oven to 350°F (180°C) and grease a 9-inch (23cm) cake pan.
In a medium bowl, whisk together the all-purpose flour, almond flour, baking powder, and salt.
In a separate large bowl, cream the butter and sugar together until light and fluffy.
Add the eggs and vanilla extract to the large bowl and mix until well combined.
Gradually add the dry ingredients to the large bowl, alternating with the milk, and mix until just combined.
Pour half of the batter into the prepared cake pan and smooth it out.
Spoon the raspberry jam over the batter and spread it out evenly.
Pour the remaining batter over the raspberry jam and smooth it out.
Bake the cake for 35-40 minutes, or until a toothpick inserted into the center of the cake comes out clean.
Let the cake cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely.
Serve the almond cake with raspberry jam and enjoy!
