How to Make Easy, Gluten-Free Monster Cookies
Ingredients:
- 1 cup (250g) creamy peanut butter
- 1/4 cup (56g) butter (at room temperature)
- 1/2 cup (106g) brown sugar
- 1/2 cup (100g) granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 cup (85g) gluten-free oats
- 1 teaspoon baking soda
- 1/2 teaspoon kosher salt
- 1/2 cup chocolate candies (like M&M’s)
- 1/2 cup chocolate chips

Directions:
- Preheat your oven to 350°F (175°C). Line large baking sheets with parchment paper or silicone baking mats to prevent sticking.
- In a large mixing bowl, use a stand mixer or hand mixer to beat the peanut butter, butter, brown sugar, and granulated sugar until light and fluffy, which should take about 1-2 minutes.
- Add in the eggs and vanilla extract, beating for another minute until creamy.
- Next, mix in the gluten-free oats, baking soda, and salt until everything is well combined.
- Fold in the chocolate candies and chocolate chips gently until they’re evenly dispersed in the dough.
- Scoop the dough into round balls, with each ball being about 1½ tablespoons. Place them on the prepared baking sheet, ensuring they are about 3 inches apart.
- Bake in the preheated oven for 10-12 minutes, or until the edges are golden brown while the centers remain soft.
- Once done, remove the cookies from the oven and let them cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely.
