Step-by-step process (detailed)
1. Preheat the oven
Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper.
2. Mix dry ingredients
In a bowl, whisk together flour, baking soda, and salt until evenly combined.
3. Cream butter and sugars
In a separate bowl, beat softened butter, peanut butter, and brown sugar until smooth, creamy, and slightly fluffy, about 2–3 minutes.
4. Add wet ingredients
Add the egg and vanilla extract, mixing until fully incorporated and smooth.
5. Combine mixtures
Gradually add the dry ingredients to the wet mixture, stirring until just combined to maintain a soft texture.
6. Add oats and mix-ins
Fold in rolled oats and optional chocolate chips or peanuts, ensuring even distribution throughout the dough.
7. Scoop the dough
Drop spoonfuls of dough onto the prepared baking sheet, spacing them slightly apart.
8. Bake
Bake for 10–12 minutes, until the edges are lightly golden and the centers remain soft.
9. Cool
Allow cookies to cool on the baking sheet for a few minutes, then transfer to a cooling rack to set properly.
10. Serve
Serve warm for a softer texture or at room temperature for a chewy bite.
