Preheat oven to 350 degrees.
Add eggs, cottage cheese, olive oil, vanilla and coconut sugar to a large mixing bowl. Whisk together until smooth.
Add in baking powder, flour and cocoa powder to the same bowl. Mix together until just combined.
Add cake batter to an 8 or 9 inch cake pan. If necessary, grease or line the pan. I used a caraway pan and lightly oiled it.
Bake cake for 30-40 minutes, until a toothpick comes out clean or until cake reads 200 degrees on a meat thermometer.
Let cake fully cool. Cool it for 10-30 minutes in the pan on a wire rack, and then for 1-3 hours out of the pan. You need the cake to be fully cooled before frosting it. To speed up the process you can refrigerate the cake for part of the cooling process, just don't put it in the fridge when it is still hot.
Add all frosting ingredients to a blender or food processor. Blend until smooth, stopping to scrape down the blender as needed.
Frost cake and top with strawberries if using, slice and enjoy.
