- Preheat oven to 325 degrees F. Line a baking sheet with parchment paper.
- Place all the ingredients into a large mixing bowl. Note that I’ve had the best luck just using whatever measurements the mix calls for.
- Whisk until just combined.
- Pour the batter onto the prepared baking sheet.
- Use an offset spatula to spread batter into a thin layer.
- Bake for 25 minutes.
