Preheat the oven to 325F. Line an 8-inch springform with parchment paper, grease it, and dust it with almond flour.
In a medium bowl, add in cane sugar, butter and sea salt. Mix all of the ingredients together using a hand mixer until it’s light and fluffy. Should take around 4 minutes.
Crack the eggs and beat them with the butter using the mixer.
Then, add cottage cheese, vanilla extract, lemon zest and lemon juice. Using a hand mixer mix for another minute.
Now, slowly add in the almond flour with baking powder and mix on a slower setting until a consistent batter is formed.
Pour the batter into the springform, smooth it out on the top, and cover with sliced almonds.
Bake in the oven for 55-60 minutes. If the top of the cake is browning up too much, cover with foil midway.
Let it cool down for 1 hour inside the form before serving.
Optional: dust with powdered sugar before serving.
