Preheat oven to 275°F. Line 12 standard muffin cups with cupcake liners or silicone liners.
In food processor, combine cottage cheese, eggs, confectioners’ sugar, cocoa powder, flour, espresso powder, and vanilla. Process until smooth, 2 minutes. Scrape down sides as needed.
2 cups low fat cottage cheese, 2 large eggs, 1 ½ cups confectioner's sugar, ⅓ cup unsweetened cocoa powder, 2 tablespoons all purpose flour, 2 teaspoons instant espresso powder, 1 teaspoon pure vanilla extract
Divide mixture among the cups and place 1 cookie on top of each.
9 chocolate wafer cookies, such as Famous
Bake until filling is set and cookies soften, 25 minutes. Let cool to room temperature in pan on a wire rack, then refrigerate at least 1 hour (or covered, up to 3 days).
To serve, invert cheesecakes onto plates and peel off liners. Top with whipped cream, chocolate syrup, or fresh fruit, if desired.
Notes
Cottage cheese note: Use full fat or lowfat cottage cheese. It doesn't really matter what size the curds are because they get pulverized in the food processor.
Filling variations: Omit espresso powder if desired, or substitute a couple drops of mint extract for a minty chocolate cheesecake. If you like, fold mini chocolate chips into the batter.
