Preheat your oven to 350 degrees.
Prepare your cookie sheet with a parchment. Alternatively, you could grease the cookie sheet and dust with some flour.
Mix the dry ingredients in a bowl and set aside.
With a hand mixer, beat the softened butter, peanut butter, and panela sugar until creamy.
Add the maple syrup, sweet potato and vanilla.
Give it another beating to incorporate and get a smooth paste.
Gently fold all the dry ingredients into the wet ingredients, using long strokes with a spatula or a quick blend with your hand mixer
Do not overmix. As soon as the flour is incorporated, take your cookie scoop or two teaspoons and form little balls, or you can take your hand. I don't like how the dough keeps sticking to my hands, and prefer the spoon method.
Drop each ball onto the parchment and when you're done, go back and flatten them all with an oily spoon or hand. Give then plenty of room to spread if you want pretty round shaped cookies. I had mine a little too close, which also increased the baking time and made them not so pretty.
Place into the oven and bake for 10-20 min. Mine actually took 30 minutes, but it's a bit of a challenge to regulate the temperature in a BBQ grill to be perfect. Lots of variables.
They are done when the edges are getting lightly browned and the cookies are looking dry. I usually press down lightly on one near the center, and if it seems pretty firm, they are done. In some Ovens you might have to rotate the sheet half way through so they bake evenly.
Serve as is which is my favorite, or frost with your favorite cream cheese frosting or a maple glaze.
