Preheat your oven to 350°F (175°C). This ensures that your cookies will bake evenly and reach the perfect texture.
In a large mixing bowl, combine the coconut oil, honey, and natural peanut butter. Use a spoon or an electric mixer to blend them until well combined. The mixture should be creamy and smooth.
Crack the egg into the bowl and add the vanilla extract. Mix again until these ingredients are fully incorporated into the batter.
In a separate bowl, whisk together the whole wheat flour, salt, baking soda, baking powder, wheat germ, oat bran, and ground flax seeds. This step ensures that the leavening agents and dry ingredients are evenly distributed.
Gradually add the dry mixture to the wet ingredients, stirring gently until just combined. Be careful not to overmix; you want the dough to be cohesive but not tough.
If you’re using peanut butter or chocolate chips, fold them into the dough now. This adds that delightful bit of indulgence to your cookies!
Using a spoon or cookie scoop, portion out the dough onto a baking sheet lined with parchment paper. Leave enough space between each cookie, as they will spread a little while baking.
Place the baking sheet in the preheated oven and bake for 10-12 minutes, or until the edges are lightly golden. The centers may look slightly underbaked, but they will firm up as they cool.
Allow the cookies to cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely. Enjoy these Mega Healthy Peanut Butter Cookies warm or store them in an airtight container for later.
