Preheat the oven to 350 F and place a rack in the center of the oven.
Line a 9” metal round pan, springform if you have it, with parchment paper or a baking spray with flour in it.
In the bowl of a stand mixer, add in the butter, sugar, salt, vanilla and almond extracts.
Use the paddle attachment to beat on medium high speed for 2 minutes until light and fluffy.
Add in the eggs, one at a time, mixing completely before adding the next. Scrape the sides and bottom of the bowl in between each egg. After the first two eggs, add in the almond flour and beat until just combined.
Then continue with the remaining two eggs.
Scrape the sides and bottom of the bowl again.
Pour in the all purpose flour and baking powder and mix again on medium speed for about 30 seconds until combined.
Pour the cake batter into the prepared pan and smooth out the top. Sprinkle with the remaining 1 tablespoon of sugar.
Bake in the preheated oven for 25 minutes until golden brown and a toothpick inserted in the center, comes out clean.
Place the baked cake on a wire rack to cool for ten minutes. Then run a knife along the edge between the cake and the pan.
Remove the spring form or tip the cake out of the pan. Leave to cool completely on a piece of parchment paper on a wire rack.
