Instructions

Mix the base ingredients: In a bowl, combine the rolled oats, 1/2 cup peanut butter, honey or maple syrup, vanilla extract, and a pinch of salt. Mix well until the mixture is cohesive and can be easily formed into shapes.
Form cookie rounds: Roll the mixture into small balls, then flatten each ball into a cookie-shaped round. Place the rounds on a parchment-lined tray to prepare for assembly.
Prepare the filling: In a separate bowl, blend 1/2 cup peanut butter with 2 to 3 tablespoons of powdered sugar until the filling is smooth and creamy, adjusting sweetness to taste.
Assemble the cookies: Spread a small amount of the peanut butter filling onto one cookie round. Then press a second cookie round on top to create a sandwich. Repeat this step for the remaining cookie rounds and filling.
Chill the cookies: Place the assembled sandwich cookies in the refrigerator and chill for 30 to 60 minutes. This step firms up the cookies for better texture and easier handling.
Serve and store: Enjoy the cookies chilled or at a cool room temperature. Store any leftovers in a covered container in the refrigerator to keep them fresh.

Notes

For a vegan option, use maple syrup instead of honey and ensure peanut butter is natural and free from animal products.
You can substitute peanut butter with almond butter or another nut butter as per preference.
If the mixture is too sticky, refrigerate it for 10–15 minutes before shaping the cookies.
Adjust the powdered sugar in the filling based on your desired sweetness level.
Store cookies properly in the fridge to maintain freshness and prevent the peanut butter filling from melting.
