Step 1Preheat the oven to 150 °C/ 300 °F (conventional), or 130 °C/ 270 °F (fan assisted) and line a baking sheet with parchment paper.
Step 2In a medium bowl beat the egg whites with an electric mixer on high with the cream of tartar until stiff peaks form, about 5 minutes.
Step 3In another bowl combine the yolks, cream cheese, and cheddar powder until smooth.
Step 4Fold the yolk mixture into the egg whites then transfer the batter to a piping bag. Pipe 5 cm (2 inch) strips (about 24) onto the baking sheet. Transfer to the oven and bake for 15 minutes.
Step 5Turn the temperature down to 120 °C/ 250 °F and slightly crack the oven door. Continue to bake for 1 hour until crispy. Store in an airtight container at room temperature for up to 5 days.
