Preheat your oven to 350°F (175°C) and grease your round cake pan.
In a bowl, combine almond flour and baking powder and whisk until blended well.
In another large bowl, beat softened butter with granulated sugar until pale and fluffy for about 3 minutes.
Add the eggs into the buttery mixture one at a time and drizzle in vanilla extract while mixing.
Gradually add the dry mix into the wet ingredients while alternating with milk and stir gently until just combined.
Pour your batter into the prepared pan and smooth out the top.
Bake for 30-35 minutes or until a toothpick comes out clean.
