Let’s Make it together
Preheat Your Oven: Preheat your oven to 350°F (175°C). Prepare baking sheets with parchment paper; this prevents sticking while ensuring easy cleanup.
Mix Dry Ingredients: In a medium bowl, whisk together oats, flour, baking soda, and salt. Set aside while you mix the wet ingredients—this keeps everything organized.
Cream Peanut Butter and Sugars: In a large mixing bowl, combine peanut butter with brown sugar and granulated sugar. Beat until fluffy, adding eggs one at a time until fully incorporated.
Add Vanilla Extract: Stir in vanilla extract into your mixture for that warm aroma. It’s like giving your cookies a cozy sweater!
Combine Wet and Dry Ingredients: Gradually fold dry ingredients into the wet mixture until just combined. Be gentle here; overmixing can lead to tough cookies!
Scoop and Shape Cookies: Use a cookie scoop or tablespoon to drop dough onto prepared baking sheets. Leave space between each scoop for spreading—nobody likes cookie puddles!
Bake for 10-12 minutes until edges are golden but centers are still soft. Allow cooling on the baking sheet before transferring to wire racks; patience is key!
Enjoy every chewy bite of these delightful peanut butter oatmeal cookies that are sure to become your new favorite treat!
