Whether you’re making them for a birthday, this recipe can be used for a special occasion or as comfort food that will have everyone coming back for seconds.

A Little History of the Chocolate and Peanut Butter Pairing

We have come a long way since these first applications, and it is genuinely historical how far chocolate and peanut butter have come to be combined into one product in the first place.

We all love the marriage of these two flavours, but it was popularised when Harry Reese invented the Reese’s Peanut Butter Cup in 1928. He was a dairy farmer and candy maker when he established H.B. Reese Candy Company in Hershey, Pennsylvania. He also played around with the chocolate and peanut butter combination, leading him to create the famous peanut butter cup. The Reese’s Peanut Butter Cup was born, melding the rich savoriness of peanut butter with the sweet smoothness of chocolate.

The Reese’s Cup helped make chocolate and peanut butter the standard combination for candies and desserts as its popularity expanded. In 1963, Reese’s was ultimately acquired by Hershey to guarantee the combination’s survival and spread to future generations.

The success of Reese’s led to other products and countless variations, such as peanut butter-filled chocolates, cookies, and cupcakes — just like the ones in the recipe you shared! Today, chocolate and peanut butter are favourite flavour combinations, and they are used in candies, baked goods, ice creams, and even savoury dishes.

This iconic pairing is ipso facto timeless, probably because of its perfect balance of sweet and salty and its appeal to people of all ages , from toddlers to elders.

The Chemistry Between Chocolate and Peanut Butter

But chocolate and peanuts make one of the best combinations because of the beautiful balance of flavours and textures, which creates this perfect and delicious experience for the taste buds. This is why this pairing is so successful:

1. Flavor Balance:

Chocolate is usually lovely, and peanut butter gives you a savoury, nutty taste. The juxtaposition awakens the palate and produces a taste—a balance. Every bite is delightful without being overly sweet because of the smooth sweetness of chocolate and the richness of peanut butter.

2. Richness:

Chocolate and peanut butter are both decadently rich ingredients on their own. Combine them, and you have a dessert that feels decadent and more than satisfying. The peanut butter and chocolate combination creates a decadent and irresistibly delicious experience with each bite.

3. Texture Contrast:

The silkiness of chocolate and the slightly grainy, creamy mouthfeel of peanut butter also work well together. This textural difference also adds to the pleasure of the dessert, as the melting buttercream peanut butter frosting will mix in your mouth with the more robust chocolate that holds the shape.

4. Nostalgic Appeal:

Chocolate and peanut butter pairings have become nostalgic favourites, with products such as Reese’s Peanut Butter Cups. That familiarity makes them a comforting, go-to treat for people of all ages, reminding us of childhood or favourites past.

5. Universally Loved:

We love the combo because it caters to a variety of palates. Chocolate and peanut butter are something that a wide range of demographics can enjoy—from kids to adults—and can be shaped to fit an array of desserts, including cakes, pastries, and cookies, making it a versatile combination in endless recipes.

And maybe no other combination has been so time-tested—no wonder it continues to be a classic go-to for making everything from candies to cupcakes to ice cream to cookies!

Tools You’ll Need for Perfect Cupcakes

To make sure your cupcakes are perfect, you will need these tools:

• Mixing Bowls: Jeff uses one for dry and wet ingredients so he doesn’t over-mix.
• Whisk and Spatula: Necessary for smooth blending and scraping every last bit of batter.
• Muffin Tin: A standard twelve-cup muffin tin will work fine for this recipe.
• Cupcake Liners: But prevent sticking and make cleanup easier.
• Piping bag and tips: Gives your frosting swirls that fancy professional look.
• Cooling rack: This lets the cupcakes cool evenly before icing.

Steps to make Chocolate Peanut Butter Cupcakes:

Step 1: Preheat the Oven

Heat the oven to 350°F (175°C) and place cupcake liners inside a 12-cup muffin pan.

Step 2: Mix Dry Ingredients

Use a whisk to mix the flour, baking soda, baking powder, cocoa powder, and salt in a medium-sized bowl.  

Step 3: Whisk together wet ingredients

In a large bowl, combine the granulated sugar, brown sugar, eggs, vegetable oil and vanilla extract and whisk until smooth.

Step 4: Add the buttermilk

Pour the buttermilk and stir until well combined. Slowly add the dry ingredients and stir until combined.

Step 5: Add Hot Water

Add the hot water gradually, while stirring, until a thin batter forms that is smooth.

Step 6: Bake the Cupcakes

Dump the batter equally into the cupcake liners, filling them two-thirds up. Bake for 18–20 minutes or until a toothpick inserted into the centre comes over. Let the cupcakes cool completely on a wire rack.

Step 7: Prepare the Frosting

 Mix the peanut and softened butter in a big bowl until smooth and creamy. Add powdered sugar, vanilla extract and salt, then mix until combined. Slowly add one tablespoon of heavy cream until the frosting meets your desired consistency.

Step 8: Frost the Cupcakes

Pipe or spread cooled cupcakes with frosting with a star tip or a spatula. For pizazz, drizzle melted chocolate or chopped peanuts on top.

Perfect Chocolate Peanut Butter Cupcake Tips

Here are some tips to bake these Chocolate Peanut Butter Cupcakes perfectly:

1. Insist on Room Temperature Ingredients

Ensure your eggs and buttermilk are at room temperature for smoother batter and better mixing.

2. Incorporate Hot Water

Adding hot water to the batter elevates the chocolate flavour and leaves the cupcakes extra moist.

3. Don’t Overmix the Batter

Do not overmix the batter, as it will yield dense cupcakes.

4. Frost After Cooling

Cool the cupcakes before frosting to avoid melting the frosting.

5. Fill Cupcake Liners Properly

Fill cupcake liners by about two-thirds   to ensure baking and rising are even.

6. Frosting with Piping Bag

To pipe frosting onto cupcakes for a professional look, use a piping bag with a star tip for smooth frosting swirls.

7. Test for Doneness

Test cupcakes at the shortest baking time with a toothpick inserted. If it comes out clean, they’re finished.

8. Store Properly

Cupcakes can stored in an airtight container for two days or refrigerated for 5 days.

Selecting Ideal Peanut Butter for Frosting

When it comes to frosting, not all peanut butter is created equal. Here’s what to look for:

1. Creamy and Smooth Peanut Butter

Use smooth, creamy peanut butter—it doesn’t have much grit, so the frosting will be silky.

2. Natural Peanut Butter

Choose natural peanut butter with 1 or 2 ingredients that deliver a rich, authentic peanut taste if possible.

3. Avoid Added Sugars or Oils

For a more straightforward taste and better consistency in frosting, use peanut butter free of added sugars or oils.

4. Salted vs. Unsalted

You may use salted or unsalted peanut butter, but adjust the salt in the recipe according to your preference.

5. Consistency

Look for peanut butter that’s pliable enough to mix easily but firm enough to keep the frosting together. If the peanut butter does not have a smooth, spreadable texture, combine it.

The Science Behind Moist and Fluffy Cupcakes

The science of moist and fluffy cupcakes is a delicate balance of ingredients and techniques. So here’s how all of those factors work together to create that ideal texture:

1. Leavening Agents (i.e. Baking Powder and Baking Soda)

• These ingredients react with wet ingredients to create air bubbles. When you bake, the gases bubble up, pushing the batter higher and giving it a light, fluffy texture.

2. Buttermilk

• Buttermilk creates an acid that reacts with baking soda, releasing carbon dioxide bubbles in the batter, which causes the cupcakes to rise. Buttermilk doesn’t develop gluten like regular milk and tenderises the batter, giving you a soft crumb.

3. Hot Water

• Adding Hotto, the batter dissolves cocoa powder, deepening the chocolate taste. The liquid also chemically breaks down the sugars, creating a smoother batter and ultimate moist cupcakes.

4. (Butters and Sugars Mixing) Creaming Method

• Creaming the butter with sugar combines them well and aerates the batter, which promotes a lighter crumb. This is crucial for creating a tender crumb.

5. Proper Mixing Technique

• Mixing too much can create excess flour gluten, resulting in heavy cupcakes. Creaming the sugar and butter together prevents overmixing when introducing the dry and wet ingredients and helps keep the batter tender and the cupcakes fluffy.

Chocolate Peanut Butter Cupcake Customization

If you’d like to play around with the frosting, here are some ideas:

1. Chocolate Ganache Frosting

• Replace the peanut butter frosting with a silky-smooth chocolate ganache. Lightly beat the heavy cream and bittersweet chocolate together for a rich, decadent topping to accompany the chocolate cupcake.

2. Frosting with Peanut Butter Cream Cheese

• Mix the peanut butter frosting with cream cheese for a tangy twist. This produces a creamy, mildly piquant taste that balances the sweetness of the cupcakes.

3. Nutella Frosting

• Add Nutella to your frosting to make it hazelnut-chocolate-flavored. This gives your cupcakes an extra slice of decadence.

4. Salted Caramel Drizzle

• Top your cupcakes with salted caramel drizzle to add sweet and savoury contrast to the chocolate and peanut butter decadence.

5. Marshmallow Fluff Frosting

• Add marshmallow fluff to the peanut butter frosting for a light, fluffy consistency and a sweet, gooey contrast to the rich cupcake base.

6. Whipped Peanut Butter Frosting

• The other is whipped peanut butter frosting, which becomes light and fluffy, delivering a creamy, melt-in-your-mouth texture while still being packed with peanut flavour.

7. Chocolate Peanut Butter Swirl

• Swirl together chocolate ganache and peanut butter frosting for a stunningly beautiful treat that celebrates both elements.

8. Maple Peanut Butter Frosting

• Use maple syrup in the peanut butter frosting. The maple flavour will be fantastic with the cupcakes’ chocolate base.

Healthier Swaps for Chocolate Peanut Butter Cupcakes

If you want to make this dessert a little healthier without compromising on flavour, give these tweaks a go:

• Whole Wheat Flour: Whole wheat flour or 50/50 blend for fibre.
• Natural Peanut butter: Natural peanut butter without sugar or oils.
• Greek Yogurt Frosting: Swap some butter in the frosting for Greek yoghurt for a protein punch.
• Dark Chocolate: Use dark chocolate chips (or cocoa powder) for an intense flavour with more antioxidants.
• Refined Sugar: Use coconut sugar as a refined sugar alternative with a lower glycemic index.

Making This Cupcake a Cake

How to Make Chocolate Peanut Butter Cupcakes into a Full-Sized Cake:

1. Double the Recipe

• Make the cupcake batter and frosting recipes, both double to have enough to make a two-layer cake.

2. Prepare Cake Pans

• Preheat oven to 350°F (180°C). Grease and line two nine-inch round cake pans with parchment paper.

3. Adjust Baking Time

• Divide the batter equally between the two pans. Mix well and pour into a bowl lined with baking paper. Bake for 25 to 30 minutes in a preheated oven at 350°F/175°C. Check at the 25-minute mark to avoid overbaking.

4. Cool the Cakes

• Let the cakes cool in the pans for about 10 minutes, then transfer to a wire rack to cool completely.

5. Layer and spread some peanut butter frosting between the two when the cakes are cool layers. Then, frost the whole cake with the rest of the frosting.

6. Decora

• For a beautiful effect, top with desired decorations, such as drizzles of melted chocolate or caramel, chopped peanuts, or swirls of frost.

How to Fix Common Cupcake Problems

Problem 1: Dry Cupcakes

• Result: Overbaking or too much flour.
• Fix: Set a timer and see if it’s done soon. Use the spoon-and-level method when measuring flour.

Problem 2: Sinking Cupcakes

• Cause: You overmixed the batter or opened the oven door too soon.
• How to correct it: Stir the batter until just combined, and don’t peek until the cupcakes are nearly done.

Problem 3: Cupcake Liners That Stick

• Cause: Too little fat in the recipe or improper cooling.
• Fix: Stick to the recipe and let cupcakes cool thoroughly before peeling away the liners.

Problem 4: Frosting Melts

• The Issue: Frosting cupcakes when they’re not entirely calm.
• Mistake: Skipping pre-cooling the cupcakes completely before decorating. If your kitchen is warm, chill the frosted briefly before piping.
