FAQs
Can I use regular flour instead of oat flour?
Yes, you can substitute regular all-purpose flour, but oat flour adds a nuttier flavor and extra fiber, making the cookies healthier.
What type of protein powder works best?
Whey or plant-based protein powders both work well. Choose a flavorless or vanilla variety to complement the sweetness and birthday cake theme.

Instructions
- Preheat Oven: Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper to prevent sticking and ensure even baking.
