Ingredients:
- For the Crust:
- 1 ½ cups graham cracker crumbs (about 12 full sheets)
- ½ cup (1 stick) unsalted butter, melted
- ¼ cup granulated sugar
- For the Peanut Butter Filling:
- 1 cup (2 sticks) unsalted butter, softened
- 3 cups powdered sugar
- 1 cup creamy peanut butter
- 1 teaspoon vanilla extract
- ¼ cup milk
- For the Chocolate Topping:
- 12 ounces semi-sweet chocolate chips
- 2 tablespoons unsalted butter
Preparing the Graham Cracker Crust
Okay, let’s get started with the foundation of our delicious bars the graham cracker crust! This is super easy and comes together in just a few minutes. Trust me, it’s the perfect base for all that peanut butter goodness to come.
- Crush the Graham Crackers: First things first, we need to turn those graham crackers into fine crumbs. You can do this in a couple of ways. My preferred method is using a food processor just toss the graham crackers in and pulse until you have a nice, even crumb. If you don’t have a food processor, no worries! Simply place the graham crackers in a large zip-top bag, seal it tightly, and use a rolling pin to crush them into crumbs. Aim for a consistency similar to coarse sand.
- Combine the Crust Ingredients: In a medium-sized bowl, combine the graham cracker crumbs, melted butter, and granulated sugar. Make sure the butter is fully melted so it incorporates evenly.
- Mix Well: Use a fork or your hands (my personal favorite!) to mix everything together until the crumbs are evenly moistened. The mixture should resemble wet sand and hold its shape when pressed together.
- Press into the Pan: Now, grab an ungreased 9×13 inch baking pan. Pour the graham cracker mixture into the pan and use the bottom of a measuring cup or your fingers to firmly press it into an even layer. Make sure to press it down really well, especially in the corners, so it forms a solid base.
- Chill the Crust: Place the pan in the refrigerator to chill for at least 30 minutes. This will help the crust set and prevent it from crumbling when you add the peanut butter filling. You can even chill it for longer if you want even overnight!
Making the Peanut Butter Filling
Alright, now for the star of the show the creamy, dreamy peanut butter filling! This is where the magic happens, and it’s so simple you won’t believe it. Just a few ingredients and a little mixing, and you’ll have the most irresistible filling ever.
- Cream the Butter: In a large bowl (or the bowl of your stand mixer), cream the softened butter until it’s light and fluffy. This usually takes about 2-3 minutes. Make sure your butter is truly softened not melted for the best results.
- Add the Powdered Sugar: Gradually add the powdered sugar, one cup at a time, mixing on low speed until it’s fully incorporated. Be careful not to add it all at once, or you’ll end up with a cloud of powdered sugar!
- Mix in the Peanut Butter and Vanilla: Add the peanut butter and vanilla extract to the bowl and mix until everything is well combined. Scrape down the sides of the bowl as needed to ensure everything is evenly mixed.
- Add the Milk: Gradually add the milk, one tablespoon at a time, until the filling reaches a smooth and creamy consistency. You might not need all of the milk, so add it slowly and check the consistency as you go. You want it to be spreadable but not too runny.
- Spread over the Crust: Remove the chilled graham cracker crust from the refrigerator. Spread the peanut butter filling evenly over the crust, making sure to reach all the way to the edges.
- Chill Again: Return the pan to the refrigerator and chill for at least 30 minutes, or until the filling is firm. This will make it easier to spread the chocolate topping without the filling mixing in.
Creating the Chocolate Topping
Last but not least, we’re adding the decadent chocolate topping! This is the perfect finishing touch that takes these bars from amazing to absolutely irresistible. It’s so easy to make, and the combination of chocolate and peanut butter is simply divine.
- Melt the Chocolate and Butter: In a heat-safe bowl, combine the chocolate chips and butter. You can melt this in the microwave or over a double boiler.
- Microwave Method: Microwave in 30-second intervals, stirring after each interval, until the chocolate is completely melted and smooth. Be careful not to overheat the chocolate, or it will seize up.
- Double Boiler Method: Place the bowl over a pot of simmering water, making sure the bottom of the bowl doesn’t touch the water. Stir constantly until the chocolate is melted and smooth.
- Stir Until Smooth: Once the chocolate is melted, stir until it’s completely smooth and glossy. The butter helps to create a nice, shiny finish.
- Pour over the Filling: Remove the pan from the refrigerator and pour the melted chocolate evenly over the peanut butter filling.
- Spread Evenly: Use a spatula or knife to spread the chocolate into an even layer, making sure to cover the entire surface of the peanut butter filling.
- Chill to Set: Return the pan to the refrigerator and chill for at least 1 hour, or until the chocolate is completely set. This is the hardest part waiting for them to be ready!
Cutting and Serving
Finally, the moment we’ve all been waiting for cutting and serving these amazing peanut butter no-bake bars! Here are a few tips to make sure they come out perfectly.
- Let them Sit: Before cutting, let the bars sit at room temperature for about 10-15 minutes. This will make them easier to cut without the chocolate cracking too much.
- Use a Warm Knife: Run a large knife under hot water, then dry it thoroughly. This will help you cut through the chocolate and peanut butter layers cleanly. Repeat this process between each cut.
- Cut into Squares: Cut the bars into squares or rectangles of your desired size. I usually cut them into about 24 bars, but you can make them smaller or larger depending on your preference.
- Serve and Enjoy: Serve the bars cold or at room temperature. They’re perfect for parties, potlucks, or just a sweet treat any time of day.
- Storage: Store any leftover bars in an airtight container in the refrigerator for up to a week. They can also be frozen for longer storage just wrap them individually in plastic wrap before freezing.
Tips and Variations
Want to customize these bars to your liking? Here are a few ideas:
- Add Chocolate Chips to the Filling: Stir in ½ cup of mini chocolate chips to the peanut butter filling for an extra chocolatey treat.
- Use Different Types of Peanut Butter: Try using crunchy peanut butter for a bit of texture, or even a flavored peanut butter like chocolate or honey.
- Add a Sprinkle of Sea Salt: Sprinkle a pinch of sea salt over the chocolate topping before it sets for a sweet and salty flavor combination.
- Make it Vegan: Use vegan graham crackers, vegan butter, and a plant-based milk alternative to make these bars vegan-friendly.
- Add Pretzels: Press crushed pretzels into the graham cracker crust for a salty and crunchy base.
