Ingredients

• 1 1/2 cups of graham cracker crumbs
• 1/3 cup of granulated sugar
• 1/2 cup of melted butter
• 1 cup of peanut butter
• 8 oz of cream cheese
• 1 cup of powdered sugar
• 1 tsp of vanilla extract
• 1 1/2 cups of whipping cream (divided)
• 1 cup of chocolate chips
• 1/2 cup of chopped peanuts
• 1/2 cup of peanut butter chips (optional)

Substitution Options

If you’re out of an ingredient or want to switch things up, here are some ideas:

• Graham cracker crumbs: Use crushed digestive biscuits or vanilla wafers.
• Peanut butter: Swap with almond butter or cashew butter for a nutty twist.
• Whipping cream: Heavy cream works just as well.
• Chocolate chips: Dark chocolate or semi-sweet chocolate chunks are great alternatives.

Preparation

Step 1: Make the Crust

Mix the graham cracker crumbs, sugar, and melted butter in a bowl until it resembles wet sand. Press this mixture firmly into the bottom of a 9-inch springform pan. The butter should help it stick together like glue. Pop it in the fridge while you work on the filling. Pro tip: Use the bottom of a glass to press the crust evenly—it’s a game-changer!

Step 2: Whip Up the Filling

In a large bowl, beat the peanut butter, cream cheese, powdered sugar, and vanilla extract until smooth and creamy. This is where the magic happens—the peanut butter adds richness, while the cream cheese keeps it light. In another bowl, whip 1 cup of the whipping cream until stiff peaks form. Fold this into the peanut butter mixture gently to keep it airy. Pour this luscious filling over the chilled crust and smooth it out with a spatula.

Step 3: Make the Ganache

Heat the remaining 1/2 cup of whipping cream in the microwave for about 30 seconds, then pour it over the chocolate chips. Let it sit for a minute before stirring until glossy and smooth. Pour this heavenly ganache over the peanut butter layer. Sprinkle chopped peanuts and peanut butter chips on top for extra crunch and flair. Chef’s tip: Toast the peanuts lightly before sprinkling them on for an even deeper flavor.

Step 4: Chill and Serve

Refrigerate the cake for at least 4 hours, though overnight is ideal. This gives the flavors time to meld and the layers to set perfectly. When you’re ready to serve, run a knife around the edges of the pan and release the springform collar. Slice and enjoy!

Timing

Here’s how long each step takes:

• Prep time: 20 minutes
• Cooking time: 0 minutes (no baking required!)
• Resting time: 4–8 hours in the fridge
• Total time: About 5 hours (mostly hands-off)

Chef’s Secret

For an extra burst of flavor, add a pinch of salt to the peanut butter filling. The salt enhances the sweetness and balances the richness of the chocolate. Trust me, it’s a small tweak that makes a big difference!

Extra Info

Did you know that peanut butter was invented in the late 1800s as a protein-rich food for people who couldn’t chew solid foods? Fast forward to today, and it’s become a beloved staple in desserts like this Irresistibly Simple Peanut Butter Cake. Fun fact: Americans eat over 700 million pounds of peanut butter each year!

Necessary Equipment

To make this cake, you’ll need:

• A 9-inch springform pan
• A mixing bowl and electric mixer
• A spatula for smoothing layers
• A microwave-safe bowl for melting chocolate
• A sharp knife for slicing

Storage

This cake stores beautifully in the fridge. Keep it covered with plastic wrap or in an airtight container to prevent it from absorbing odors. It stays fresh for up to 5 days, though I doubt it’ll last that long!

If you want to freeze it, wrap individual slices tightly in plastic wrap and place them in a freezer-safe bag. They’ll keep for up to 2 months. Just thaw them in the fridge overnight before serving.

Pro tip: Always let the cake come to room temperature for 15–20 minutes before slicing. This ensures clean cuts and maximum flavor.

Tips and Advice

• Use full-fat whipping cream for the best texture in both the filling and ganache.
• Don’t skip chilling the cake—it’s crucial for setting the layers.
• If you’re short on time, pop the cake in the freezer for 1–2 hours instead of refrigerating it.

Presentation Tips

• Serve slices on pretty dessert plates with a dollop of whipped cream.
• Garnish with extra chocolate shavings or a drizzle of melted peanut butter.
• Add a sprig of mint for a pop of color.

Healthier Alternative Recipes

Want to lighten up this cake? Here are six variations:

1. Low-Sugar Version: Use sugar-free peanut butter and a sugar substitute for the powdered sugar.
2. Vegan Option: Substitute dairy-free cream cheese, butter, and whipping cream.
3. Gluten-Free Twist: Use gluten-free graham crackers for the crust.
4. Lightened-Up Filling: Replace half the cream cheese with Greek yogurt.
5. Dark Chocolate Ganache: Use dark chocolate chips for a richer, less sweet topping.
6. No-Bake Cheesecake Style: Omit the peanut butter chips and focus on the creamy filling.

Common Mistakes to Avoid

Mistake 1: Skipping the Chilling Time

One of the biggest mistakes is rushing the chilling process. Without enough time in the fridge, the layers won’t set properly, and the cake will fall apart when sliced. Be patient—it’s worth the wait!

Mistake 2: Overmixing the Whipped Cream

When folding the whipped cream into the peanut butter mixture, be gentle. Overmixing can deflate the cream, making the filling dense instead of light and airy. Pro tip: Use a spatula and fold in slow, deliberate motions.

Mistake 3: Using Old Chocolate Chips

Old or low-quality chocolate chips can seize when mixed with warm cream, ruining your ganache. Always check the expiration date and opt for high-quality chocolate for the best results.

FAQ

Can I use crunchy peanut butter?
