Ingredients for Peanut Butter Sandwich Cookies

Gathering the ingredients is the first step toward cookie bliss. Here’s what you’ll need for these delightful Peanut Butter Sandwich Cookies:

Unsalted Butter: Softened butter adds richness and flavor. You can substitute with margarine if you’re in a pinch.
Brown Sugar: This gives the cookies a lovely moisture and depth of flavor. Use light or dark according to your preference.
Granulated Sugar: It balances the sweetness and helps with the cookie’s texture.
Smooth Peanut Butter: Your nutty superstar! You can opt for crunchy if you enjoy a bit of texture or even almond butter for something different.
Large Egg: This binds everything together while providing a touch of moisture. If you’re egg-free, a flaxseed meal substitute can work.
Vanilla Extract: A little splash of vanilla enhances the flavors of the other ingredients. No extract? Vanilla essence will do!
All-Purpose Flour: This forms the base of the cookies, aiding in structure. Whole wheat flour works too if you’re feeling health-conscious.
Baking Soda: Essential for leavening, it helps the cookies rise. Don’t skip this; your cookies will miss the lift!
Salt: Just a pinch to elevate the sweet flavors and balance the taste.
Quick Oats: These add texture and chewiness. You can swap them for rolled oats, just pulse them a bit into smaller bits.
For the Filling:
Unsalted Butter: Again, for smoothness in your filling.
Smooth Peanut Butter: Bring this back for a double dose of peanutty goodness!
Powdered Sugar: This creates a sweet and creamy filling. Feel free to adjust to your taste for a sweeter or milder finish.
Whipping Cream or Milk: To achieve that perfect creamy consistency. Use what you have on hand!

How to Make Peanut Butter Sandwich Cookies

Step 1: Preheat and Prepare

Let’s kick things off by preheating your oven to 350°F (180°C). While that’s warming up, grab your cookie sheets and line them with parchment paper or a baking mat. This will prevent sticking and make cleanup a breeze. Trust me, using parchment paper is a game-changer! It gives your cookies a lovely base to sit on. Also, be sure to set your space up for success. A tidy kitchen makes all the difference!

Step 2: Cream the Base Ingredients

In a large mixing bowl, combine the softened butter, light brown sugar, and granulated sugar. Using an electric mixer, beat them together until they become light and fluffy—about 3-4 minutes. Don’t rush this step; the fluffiness will help your cookies rise and maintain that soft texture we all adore. Once mixed, add in smooth peanut butter. This nutty wonder adds the irresistible flavor that makes these Peanut Butter Sandwich Cookies so delicious!

Step 3: Incorporate the Egg and Vanilla

Now, it’s time to elevate our mixture! Crack in one large egg and pour in a teaspoon of vanilla extract. Give everything a good mix until well-combined. This step helps bind our cookie dough together while enhancing that classic cookie flavor. The sweet aroma of the vanilla is already hinting at what’s to come!

Step 4: Combine Dry Ingredients

In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. Once that’s done, gradually add this flour mixture to your creamed ingredients. Mix on low speed to avoid a cloud of flour in your face! Lastly, fold in the quick oats—I like to mix until just combined for a smooth texture, ensuring no flour streaks remain. This creates a delightful chewiness that’s essential for our cookies.

Step 5: Form and Bake Cookie Dough

Let’s bring those cookies to life! Using a tablespoon, scoop out dough and roll into balls. Aim for about 1 to 1.5 tablespoons each. Place them about 2 inches apart on your prepared baking sheets. A slightly wet hand helps to flatten them gently; this way, they’ll bake evenly. Bake in your preheated oven for 8-11 minutes until the tops look set. Your kitchen will be filled with the most delightful smell as they bake!

Step 6: Cool the Cookies

After baking, let the cookies cool on the baking sheets for about 10-15 minutes. This cooling time is crucial! It allows them to firm up, making them easier to transfer to a wire rack without falling apart. After that, let them cool completely before frosting; this keeps the filling from melting. Patience, friends, it’s so worth it!

Step 7: Prepare the Peanut Butter Filling

While your cookies cool, let’s whip up that creamy peanut butter filling! In a separate bowl, beat the softened butter until it’s smooth. Then, blend in the smooth peanut butter until well mixed. Gradually add powdered sugar, starting on low speed to avoid a sugary explosion. Finally, mix in whipping cream or milk, a tablespoon at a time, until you achieve that divine creamy consistency. It should be thick but spreadable—a true dream come true!

Step 8: Assemble the Sandwich Cookies

The moment of truth has arrived—assembly time! Take one cookie and spread about a tablespoon of the luscious peanut butter filling on the bottom. Top it off with another cookie and gently press down to create your sandwich. Repeat until all your cookies are filled. You’ve created a delectable treat that your family will absolutely adore!

Tips for Success

Always use room temperature ingredients for better mixing and fluffiness.
Measure flour accurately; spoon it into the cup and level it off.
Chill the dough for 30 minutes if it’s too sticky to handle.
Experiment with add-ins like chocolate chips or nuts for extra flavor.
For a crunchier texture, bake a minute longer.

Equipment Needed

Mixing Bowls: Use a large bowl for mixing; any bowl will do in a pinch!
Electric Mixer: A hand mixer is great; a sturdy whisk works too with a bit more effort.
Baking Sheets: Cookie sheets are ideal; you can use any flat baking dish.
Parchment Paper: This helps prevent sticking; silicone mats are a neat alternative.
Cooling Rack: Essential for cooling; a simple plate can work if you’re in a hurry.

Variations on Peanut Butter Sandwich Cookies

Chocolate Peanut Butter Sandwich Cookies: Add cocoa powder to the dough for a chocolatey twist. Use dark chocolate for the filling.
Nutty Oatmeal Filling: Replace half of the peanut butter in the filling with almond or cashew butter for a new flavor profile.
Gluten-Free Option: Substitute all-purpose flour with a gluten-free flour blend to enjoy these cookies without the gluten.
Vegan Adaptation: Use a plant-based butter substitute and replace the egg with a flax egg or applesauce for a delicious vegan treat.
Spiced Cookies: Add cinnamon or nutmeg to the cookie dough for a warm flavor that dances on your taste buds.
