Step-by-step process (detailed)
1. Preheat the oven
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. A properly heated oven ensures even baking and prevents spreading issues.
2. Cream butter, peanut butter, and sugars
In a large bowl, beat the softened butter, peanut butter, brown sugar, and granulated sugar for 3–4 minutes until the mixture is smooth, creamy, and slightly fluffy. This step incorporates air, helping create a chewy yet tender texture.
3. Add eggs and vanilla
Add eggs one at a time, mixing well after each addition to fully incorporate. Stir in vanilla extract and mix until the batter looks smooth and glossy.
4. Mix dry ingredients
In a separate bowl, combine oats, baking soda, and salt. This ensures even distribution of leavening and seasoning.
5. Combine wet and dry
Gradually add the oat mixture to the wet ingredients, mixing gently until fully combined. The dough will be thick and slightly sticky.
6. Fold in mix-ins
Fold in chocolate chips and candy-coated chocolates evenly, ensuring each scoop will have a balanced mix of ingredients.
7. Portion the dough
Use a cookie scoop or spoon to portion dough into balls (about 2 tablespoons each). Place them on the baking sheet with space between each cookie.
8. Shape the cookies
Lightly flatten each dough ball slightly with your hand. These cookies don’t spread much, so shaping helps achieve the right thickness.
9. Bake
Bake for 10–12 minutes until edges are set and lightly golden while centers remain soft. The cookies will continue to firm up as they cool.
10. Cool and serve
Let cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack. Serve once cooled or slightly warm.

Overbaking — dry cookies
Skipping flattening — uneven shape
