1-First Step: Gather and Prep Your Ingredients Start by getting all your ingredients ready to make things smooth. Measure out 1/2 cup butter (115 g), 1/2 cup granulated sugar (100 g), and the rest as listed. Let the butter and egg sit at room temperature for about 10 minutes. This prep takes roughly 5 minutes and sets you up for success.

2-Second Step: Cream the Butter and Sugars In a large bowl, cream the 1/2 cup butter (115 g) with 1/2 cup granulated sugar (100 g) and 1/2 cup brown sugar (110 g) for 2-3 minutes until it’s light and fluffy. Use a hand mixer or stand mixer for this it makes the dough easier to work with and ensures even texture.

3-Third Step: Add the Wet Ingredients Mix in 1/2 cup peanut butter (130 g) until it’s fully blended, then beat in 1 large egg and 1 teaspoon vanilla extract (5 ml). This step should take about 1 minute and helps create that rich, cohesive dough we love.

4-Fourth Step: Combine the Dry Ingredients In another bowl, whisk together 1 cup all-purpose flour (120 g), 1 1/4 cups rolled oats (112 g), 1/4 teaspoon salt (1.5 g), 1/2 teaspoon baking powder (2 g), and 1/2 teaspoon baking soda (2.5 g). Gradually add this to the wet mixture, stirring just until combined to avoid over-mixing.

5-Fifth Step: Mix in the Add-Ins Fold in 3/4 cup candy-coated chocolate pieces (130 g) and 1/2 cup chocolate chips (90 g) by hand. This keeps the chunks intact for that monster effect and takes about 1 minute.

6-Sixth Step: Preheat and Shape the Dough Preheat your oven to 350°F (175°C) while you drop tablespoon-sized balls of dough onto baking sheets lined with parchment paper. Space them about 2 inches apart to allow for spreading. Chilling the dough for 15-30 minutes here can help keep them thick it’s a great tip for best results!

7-Seventh Step: Bake the Cookies Bake for 10-12 minutes until the edges are set but the centers are still soft. Keep an eye on them after 10 minutes to prevent over-baking. This step is crucial for that chewy texture, and it locks in all the flavors.

8-Final Step: Cool and Enjoy Remove the cookies from the oven and let them cool on the baking sheet for 5-10 minutes; they’ll firm up as they rest. Once cooled, transfer to a wire rack. Serve them warm with a glass of milk for the ultimate treat! If you’re looking for more cookie inspiration, try our peanut butter chocolate molten lava cake for a decadent twist.
