Equipment
Method
- Preheat oven to 300 degrees F. Line a baking sheet with parchment paper.
- Drain cottage cheese by pouring off all excess liquid. Blend until completely smooth using a food processor or immersion blender. Set aside.
- In a large, clean, dry bowl, beat egg whites with cream of tartar on medium-high speed until stiff peaks form, about 2 to 4 minutes. Bowl and beaters must be completely free of grease or yolk.
- In a separate bowl, whisk together egg yolks, blended cottage cheese, cornstarch, powdered sweetener, vanilla extract, and lemon zest until smooth.
- Stir one third of the whipped egg whites into the yolk mixture to lighten it. Pour the lightened mixture over the remaining whites and fold gently using a rubber spatula in wide sweeping motions. A few white streaks are fine. Do not overmix.
- Gently fold in blueberries with 2 to 3 strokes, distributing evenly without deflating the batter.
- Scoop batter using a quarter-cup measuring cup onto the prepared baking sheet, spacing about 2 inches apart. Lightly flatten each mound with the back of a spoon.
- Bake at 300 degrees F for 25 to 27 minutes until golden brown and firm to the touch. Do not open the oven door during baking. Cool on the baking sheet a few minutes before transferring to a wire rack. Texture firms further as they cool.
Notes
Best eaten within 12 hours. Store leftovers in an airtight container in the fridge for up to 3 days. Do not freeze. Serve at room temperature or refresh in a 275 degree F oven for 5 minutes. Bowl and beaters must be completely clean and dry before whipping egg whites. If using frozen blueberries, pat completely dry to avoid a runny batter.
