Description

These No-Bake Peanut Butter Oatmeal Sandwich Cookies are a quick and easy treat combining creamy peanut butter, nutritious oats, and a touch of natural sweetness from honey or maple syrup. Perfect for a wholesome snack or a simple dessert, they require no baking and come together in just minutes.


Ingredients

Scale

Cookie Base

  • 1 cup rolled oats
  • 1/2 cup peanut butter (creamy or crunchy)
  • 1/4 cup honey or maple syrup
  • 1/2 teaspoon vanilla extract
  • Pinch of salt

Filling

  • 1/2 cup peanut butter
  • 2–3 tablespoons powdered sugar (to taste)


Instructions

  1. Combine Ingredients: In a bowl, mix rolled oats, 1/2 cup peanut butter, honey or maple syrup, vanilla extract, and a pinch of salt until the mixture is well combined and holds together cohesively.
  2. Form Cookies: Roll the mixture into small balls and then flatten each ball into cookie-shaped rounds. Place these on a parchment-lined tray for easy handling.
  3. Prepare Filling: In a separate bowl, blend 1/2 cup peanut butter with 2 to 3 tablespoons powdered sugar until the filling is smooth and creamy, adjusting sweetness to your preference.
  4. Assemble Sandwiches: Spread a small amount of the peanut butter filling onto one cookie round, then gently press a second cookie on top to create a sandwich.
  5. Repeat Assembly: Continue assembling the remaining cookies and filling until all have been used.
  6. Chill: Place the assembled sandwich cookies in the refrigerator for 30 to 60 minutes to firm up and set properly before serving.
  7. Serve and Store: Enjoy the cookies chilled or at cool room temperature. Store any leftovers covered in the refrigerator to maintain freshness.

Notes

  • You can use either creamy or crunchy peanut butter based on your texture preference.
  • Adjust the amount of powdered sugar in the filling to suit your desired sweetness level.
  • These cookies are best when kept refrigerated but can be served at room temperature for a softer texture.
  • For a nut-free version, substitute peanut butter with sunflower seed butter.
  • Make sure to use rolled oats and not instant oats for better texture and binding.
