In a mixing bowl, combine cottage cheese, lemon juice, lemon zest, honey, and vanilla extract until smooth.
Add almond flour, baking powder, and salt to the mixture, stirring until fully combined.
Pour the batter into a microwave-safe mug, filling it halfway to allow for rising.
Microwave on high for 1 to 2 minutes, checking for doneness until the cake is set and a toothpick comes out clean.
