1-First Step: Start by preheating your oven to 350°F (177°C) and lining your baking sheets with parchment paper or silicone mats. This ensures even baking and easy cleanup, so your cookies come out just right without sticking. Gather all ingredients to make the process smooth having everything measured out helps avoid any mid-recipe rushes.

2-Second Step: In a medium bowl, whisk together the 3/4 cup all-purpose flour, 1 cup old-fashioned whole rolled oats, 1/2 teaspoon baking soda, 1/2 teaspoon baking powder, and 1/2 teaspoon salt. This dry mix forms the base of your cookies, providing structure and a hearty texture from the oats. Mixing these first lets the leavening agents distribute evenly for fluffy results.

3-Third Step: In a large bowl, beat the 1/3 cup unsalted butter, 3/4 cup packed light or dark brown sugar, and 1/4 cup granulated sugar until creamy, which takes about 2 minutes with a hand mixer. Add in the 2/3 cup creamy peanut butter, 1 large egg at room temperature, and 1 teaspoon pure vanilla extract, then mix until fully combined. This creates a smooth, peanutty dough that’s the heart of the cookie.

4-Fourth Step: Gradually stir the dry ingredients into the wet mixture on low speed until just combined, avoiding overmixing to keep the cookies tender. The dough should be sturdy and easy to handle, thanks to the peanut butter. Scoop the dough into 2-heaping-teaspoon balls, place them 3 inches apart on your prepared sheets, and flatten them gently with your fingers or a fork.

5-Fifth Step: Bake the cookies for 10-11 minutes until the edges are lightly browned. Let them cool on the sheets for 5 minutes, then transfer to wire racks to cool completely. This resting time helps them set without becoming too crisp. While they cool, prepare the frosting by beating 1 cup creamy peanut butter, 1 tablespoon honey, and 1/4 cup confectioners’ sugar until smooth and spreadable.

6-Final Step: Once cooled, spread or pipe the frosting onto the flat side of one cookie and top it with another to form a sandwich.
