Preheat oven to 425°F (220°C). Line a 9x13-inch baking sheet with parchment paper and grease lightly.
Whisk together eggs, cottage cheese, vanilla essence, lemon juice, and sugar or honey in a medium bowl until smooth.
In another bowl, mix flour, baking powder, and kosher salt until combined.
Add the dry ingredients to the wet mixture and stir gently until just combined, avoiding overmixing.
Pour batter evenly into the prepared baking sheet and scatter sliced strawberries on top.
Bake for 15 minutes until golden brown and puffed.
Remove from oven, slice into squares, and serve warm with extra strawberries, powdered sugar, and maple syrup.
