Whip Up Garlic Butter: In a small bowl, simply whisk together the melted butter, minced garlic, grated Parmesan, fresh parsley, and coarse salt. Set this delicious mix aside.
Preheat & Prep: Get your oven ready by preheating it to 325°F (160°C). Line a baking sheet with parchment paper and give the parchment a light grease for easy breadstick removal.
Mix Dry Goodies: In a spacious bowl, combine the almond flour, coconut flour, protein powder, baking powder, salt, and garlic powder. Give them a quick whisk to blend everything evenly.
Add Wet Wonders: Pour in the olive oil, eggs, and egg whites. Mix until all ingredients are well combined into a dough. Let it rest for just 5 minutes to help it firm up slightly.
Shape Your Breadsticks: Lightly moisten your hands. Divide the dough into 12 equal portions. Roll each portion into a log, aiming for about 1 inch wide and 4 inches long. Place these logs onto your prepared baking sheet, ensuring they're spaced 2 to 3 inches apart (they will spread a little).
First Bake & Brush: Brush half of your fantastic garlic butter mixture over the unbaked breadsticks. Pop them into the preheated oven and bake for about 15 minutes, or until they're beautifully golden brown and firm to the touch.
Final Flavor Boost: Once baked, take them out of the oven and let them cool for 10 minutes. Then, brush the remaining garlic butter generously over the warm breadsticks. Serve them warm and savor every bite!
