Preheat oven to 350 degrees F. 

Place butter, peanut butter, egg, brown sugar, and honey in a large mixing bowl. Use hand mixer to mix on medium speed for 1 minute 15 seconds. The mixture will be light and creamy.

Add vanilla, baking soda, and salt. Combine. 

Add chocolate chips, sunflower seeds, and oats. Stir with a spoon to fully combine and coat all ingredients. The dough will be wet. That's okay! You don't need to add more oats.

Use a cookie scoop or spoon, and place about a tablespoon of dough onto parchment lined cookie sheet. These are more like drop cookies. Do not try and use your hands to make round balls.

Bake for 11 minutes, until cookies are just set in the middle with brown edges.
