- 1/2 cup brown sugar (105 grams) (packed)
- 1/3 cup granulated sugar (66 grams)
- 1/2 cup smooth peanut butter (130 grams) (smooth, commercially prepared)
- 1 large egg

- 1/2 teaspoon baking powder

- 1/4 teaspoon salt
For the Add-ins

How to Make Peanut Butter Oatmeal Chocolate Chip Cookies
Step 1: Preheat the Oven
Preheat your oven to 350°F (180°C or 170°C on a convection oven). Line cookie sheets with baking paper or silicone baking mats.
Step 2: Cream the Butters and Sugars
In a large bowl, beat together the softened butter, brown sugar, granulated sugar, and peanut butter until well combined.
Step 3: Add Egg and Vanilla
Beat in the large egg and vanilla extract until smooth.
Step 4: Mix in Dry Ingredients
Add in the flour, baking powder, baking soda, and salt. Mix into the batter starting with a few stirs before turning on your mixer to low speed until fully incorporated.
Step 5: Stir in Oats
Add in the oats and stir by hand until evenly mixed.
Step 6: Incorporate Chocolate Chips
Stir in 3/4 cup of chocolate chips. Save the remaining 1/4 cup for dotting on top of each cookie if desired; alternatively, mix all chips into the dough.
Step 7: Form Cookie Dough Balls
Form dough balls using about 3 tablespoons of dough each. A large cookie scoop works well here; if you don’t have one, use two spoons. If sticky, consider chilling the dough for about 30 minutes.
Step 8: Bake Cookies
Place dough balls on lined cookie sheets about 2-3 inches apart. Bake in preheated oven for about 10-12 minutes or until tops look just set.
Step 9: Cool Down
Remove from oven and cool cookies on cookie sheets for at least 10 minutes. Optionally place a few extra chocolate chips on top of each warm cookie before serving.
