Peanut Butter Bars With Chocolate Ganache

The scent of peanut butter always takes me back to childhood. Rainy afternoons spent indoors were invariably brightened by my grandmother’s baking. While chocolate chip cookies were a frequent treat, it was her peanut butter bars, rich and decadent with a smooth chocolate ganache, that truly captured my heart. Each bite was a perfect blend of salty-sweet, a comforting indulgence that warmed me from the inside out. Now, decades later, I’ve recreated that nostalgic flavor in my own kitchen, eager to share this timeless classic with you.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 35-40 minutes
• Total Time: 1 hour 10 minutes (includes cooling time)
• Servings: 24
• Yield: 24 bars
• Dietary Type: Not specified (contains dairy, eggs, gluten)

Ingredients

• 2 cups flour
• 2 cups granulated sugar
• 1 teaspoon salt
• 1 teaspoon baking soda
• ¾ cup peanut butter
• 1 cup butter
• 1 cup water
• 2 eggs
• ½ cup buttermilk

For the Ganache:

• ½ cup semi-sweet chocolate chips
• ⅓ cup whipping cream

Equipment Needed

• 13 x 9 inch baking dish
• Mixing bowls
• Measuring cups and spoons
• Microwave-safe bowl

Instructions

1. Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). This is crucial for even baking and prevents the bars from becoming too dry.
2. Grease and flour a 13 x 9 inch baking dish. This prevents the bars from sticking and ensures easy removal. A light dusting of flour after greasing works best.
3. In a large mixing bowl, combine the flour, sugar, salt, and baking soda. Whisk these dry ingredients together thoroughly to ensure even distribution. This prevents pockets of baking soda or salt, which can affect the taste and texture of the bars. Set the bowl aside.
4. In a saucepan over medium heat, combine the peanut butter, butter, and water. Bring the mixture to a boil, stirring frequently to prevent scorching. Make sure the butter is completely melted and the peanut butter is incorporated smoothly.
5. Carefully pour the hot peanut butter mixture into the bowl with the flour mixture. Mix until just combined. Avoid overmixing at this stage, as it can lead to tough bars.
6. Add the eggs and buttermilk to the batter. Mix well until everything is fully incorporated and the batter is smooth. The buttermilk adds a slight tang and helps to tenderize the bars.
7. Pour the batter into the prepared baking pan and spread it evenly.
8. Bake for 35-40 minutes, or until a wooden skewer inserted into the center comes out clean. Keep a close eye on the bars towards the end of the baking time to prevent overbaking. Ovens can vary, so adjust the baking time as needed. If the top starts to brown too quickly, tent the pan with foil.
9. Remove the bars from the oven and let them cool in the pan for 30 minutes before frosting. This allows them to firm up slightly, making them easier to handle.
10. While the bars are cooling, prepare the ganache. In a microwave-safe bowl, combine the chocolate chips and whipping cream. Microwave for 1 minute, stirring halfway through, until the chocolate is melted and the mixture is smooth. If needed, microwave in additional 15-second intervals, stirring after each interval, until melted.
11. Pour the ganache over the cooled bars and spread it evenly.
12. Refrigerate the bars until the ganache is set before cutting into squares and serving. This usually takes about 30 minutes to an hour.

Expert Tips & Tricks

• For a richer peanut butter flavor, use natural peanut butter (the kind you need to stir) in the batter. Just make sure to stir it well before measuring.
• If you don’t have buttermilk, you can make a substitute by adding 1 ½ teaspoons of white vinegar or lemon juice to ½ cup of milk. Let it sit for 5 minutes before using.
• To ensure the bars are evenly baked, rotate the pan halfway through the baking time.
• For a cleaner cut, chill the bars thoroughly before slicing. Use a warm knife to make smooth, even cuts.
• Want to elevate the presentation? Sprinkle the ganache with chopped peanuts or a pinch of sea salt before it sets.

Serving & Storage Suggestions

These peanut butter bars are best served chilled. The cool ganache provides a delightful contrast to the rich, chewy base. They’re perfect as an afternoon treat, a party dessert, or a potluck contribution.

To store, keep the bars in an airtight container in the refrigerator for up to 5 days. You can also freeze them for up to 2 months. Wrap them individually in plastic wrap before placing them in a freezer-safe container to prevent freezer burn. To thaw, transfer the bars to the refrigerator overnight or let them sit at room temperature for a few hours.

Variations & Substitutions

• Gluten-Free: Substitute the all-purpose flour with a gluten-free blend. Be sure to choose a blend that is designed for baking and contains xanthan gum for binding.
• Dairy-Free: Replace the butter with a dairy-free butter alternative. Substitute the buttermilk with a mixture of ½ cup of non-dairy milk and 1 ½ teaspoons of lemon juice or white vinegar. Use dairy-free chocolate chips and coconut cream instead of whipping cream for the ganache.
• Different Nut Butter: Experiment with almond butter, cashew butter, or sunflower seed butter for a different flavor profile.
• Add-Ins: Stir in chocolate chunks, chopped nuts, or toffee bits into the batter for added texture and flavor.

FAQs (Frequently Asked Questions)

Q: Can I use creamy peanut butter instead of regular peanut butter?
A: Yes, you can use creamy peanut butter. It will result in a slightly smoother texture, but the difference is minimal.

Q: What if I don’t have buttermilk?
A: You can easily make a buttermilk substitute by combining ½ cup of regular milk with 1 ½ teaspoons of lemon juice or white vinegar. Let it sit for 5 minutes before using.

Q: How do I prevent the chocolate ganache from seizing?
A: Be careful not to overheat the chocolate and cream mixture. Microwave in short intervals, stirring frequently. If it does seize, try adding a teaspoon of hot water at a time and stirring until smooth.

Q: Can I make these bars ahead of time?
A: Absolutely! These bars are perfect for making ahead of time. Simply bake, cool, and frost them, then store them in the refrigerator until ready to serve.

Q: How do I know when the bars are done baking?
A: Insert a wooden skewer into the center of the bars. If it comes out clean or with a few moist crumbs attached, they are done. Be careful not to overbake, as this can make them dry.
