Monster Cookie Recipe
Active Time: 10 minutes
Total Time: 1 hour
Yield: 8 cookies
Ingredients:
¾ cup butter or coconut oil, melted
¾ cup brown sugar
⅓ cup sugar
1 ½ tsp vanilla extract
1 egg
½ cup creamy peanut butter
1 ¼ cups all purpose flour
¾ cup rolled oats
1 teaspoon baking powder
½ tsp baking soda
½ tsp sea salt
½ cup Thrive Market Organic Chocolate Chunks

1 cup pretzels, broken into bite-sized pieces
Instructions:
Combine melted butter, brown sugar, granulated sugar, and vanilla in a mixing bowl. Whisk in the egg and peanut butter.
Add the flour, oats, baking powder, baking soda, and salt. Stir with a spatula until a thick dough forms.
Add the chocolate gems, pretzels, and chocolate chunks. Stir until combined.
Divide the dough into ⅓ cup portions. Roll each portion into a ball and place them on a plate. Cover and refrigerate the dough balls for 30 minutes.
While the dough is chilling, preheat the oven to 350ºF. Line a baking sheet with parchment paper.
Place 4 cookies on a baking sheet and bake for 14-16 minutes (this recipe will require two separate baking sheets). Let cool briefly before serving.
