What Are Peanut Butter Mountain Bars?

Peanut Butter Mountain Bars are layered bars that start with a crunchy base (often made from graham crackers or oats) and are topped with a creamy peanut butter layer and a rich chocolate topping. The combination of textures—crunchy, creamy, and smooth—makes each bite an irresistible experience.

These bars are similar to no-bake peanut butter bars but with a bit of extra indulgence. The “mountain” part of the name refers to the layers that rise like a “mountain” of peanut butter goodness, creating a delicious contrast between the layers of crunch and the smooth, creamy peanut butter filling.

Whether you serve them as a dessert or an indulgent snack, Peanut Butter Mountain Bars are sure to be a hit with anyone who loves the flavor of peanut butter and chocolate.

Ingredients for Peanut Butter Mountain Bars

Making these bars is surprisingly simple, and the ingredients are easy to find in your local grocery store. Here’s what you’ll need:

For the Base:

• 1 1/2 cups graham cracker crumbs (or crushed digestive biscuits)
• 1/2 cup unsalted butter, melted
• 1/4 cup powdered sugar
• 1 cup rolled oats (optional for added texture)

For the Peanut Butter Layer:

• 1 cup creamy peanut butter
• 1/2 cup unsalted butter, softened
• 2 cups powdered sugar
• 1 teaspoon vanilla extract

For the Chocolate Topping:

• 1 1/2 cups semisweet chocolate chips
• 2 tablespoons unsalted butter

How to Make Peanut Butter Mountain Bars

Making Peanut Butter Mountain Bars is a simple process with just a few steps. Here’s how to do it:

Step 1: Prepare the Base

1. In a medium-sized bowl, combine the graham cracker crumbs, melted butter, powdered sugar, and oats (if using). Mix everything together until the mixture is well-combined and the crumbs are fully coated.
2. Press the mixture into the bottom of a greased 9×13-inch baking dish to form an even, compact layer. Use the back of a spoon or your fingers to press it down firmly.
3. Place the dish in the fridge to chill while you prepare the peanut butter layer.

Step 2: Make the Peanut Butter Layer

1. In a large bowl, combine the peanut butter, softened butter, powdered sugar, and vanilla extract. Stir until smooth and creamy.
2. Once the mixture is smooth, spread it evenly over the chilled graham cracker base. Use a spatula to smooth it out to the edges, ensuring a uniform layer.

Step 3: Prepare the Chocolate Topping

1. In a small saucepan, melt the chocolate chips and butter over low heat, stirring constantly until the mixture is smooth and well combined. Alternatively, you can melt the chocolate and butter together in a microwave-safe bowl in 30-second increments, stirring in between.
2. Once the chocolate is melted, pour it over the peanut butter layer, spreading it evenly with a spatula.

Step 4: Chill and Serve

1. Place the dish back in the fridge for at least 2 hours to allow the bars to set completely. This helps the layers firm up and makes them easier to cut.
2. Once the bars have chilled and set, remove them from the fridge and cut them into squares or rectangles, depending on your preference.

Tips for Perfect Peanut Butter Mountain Bars

• Use Room Temperature Butter: When making the peanut butter layer, it’s best to use softened butter to ensure the mixture is smooth and easy to spread.
• Chill Between Layers: Make sure to chill the base layer before adding the peanut butter and chocolate layers. This ensures that each layer stays distinct and firm.
• Allow the Bars to Fully Set: While the temptation to dig in early is real, allowing the bars to chill for at least 2 hours will give you the best texture and make them easier to slice.
• Customize the Toppings: Feel free to get creative with your toppings! Add crushed peanuts, a sprinkle of sea salt, or drizzle some caramel or white chocolate for extra flair.

Variations of Peanut Butter Mountain Bars

While the original Peanut Butter Mountain Bars are delicious as they are, there are plenty of fun variations you can try to make them your own:

• Add Crunch: For added texture, sprinkle some crushed peanuts, pretzels, or rice krispies on top of the peanut butter layer before adding the chocolate.
• Use Dark Chocolate: If you prefer a richer, less sweet taste, opt for dark chocolate chips instead of semisweet chocolate.
• Caramel Layer: Add a layer of caramel in between the peanut butter and chocolate layers for an extra sweet surprise.
• White Chocolate Drizzle: For a beautiful contrast, drizzle some melted white chocolate over the top of the bars after they’ve set.

How to Store Peanut Butter Mountain Bars

Peanut Butter Mountain Bars should be stored in an airtight container in the fridge. They’ll stay fresh for up to a week, but chances are, they won’t last that long! The cold helps maintain their firm texture and ensures that the chocolate stays solid. If you want to store them for longer, you can freeze the bars for up to a month. Simply cut them into individual pieces, place them in a freezer-safe container, and layer them with parchment paper to prevent sticking.
