Preheat oven to 350°F (180°C). Line a baking sheet with parchment paper.
Make flax Egg: In a small bowl, mix together 3 tbsp water and 1 tbsp ground flax. Let sit for 5-10 minutes until it forms a gel like consistency. This acts as our egg replacer and helps bind everything together!
In a medium bowl, whisk together the sunflower seed butter, coconut sugar, flax egg, and vanilla until smooth.
Add protein powder, almond flour, baking soda, and salt. Mix until a thick dough forms.
Fold in the dye-free candy-coated chocolate chips.
Using a small cookie scoop or ice cream scoop, scoop the dough into 9-12 balls (about 2 tablespoons each). Roll the dough together using your hands so that it all sticks together and gently flatten into cookie shapes.
Bake for 9–11 minutes, until edges are set but centers are still soft. Gently press 2–3 candy eyeballs into each cookie while they are still warm so that they’ll stick better. I like to also press in a few extra dye-free candy coated chocolate chips. Don't press too hard or you will press right into the center of the cookie.
Cool on the pan for at least 15 minutes before transferring. Cookies will firm up as they cool.
