Reeses Peanut Butter Cupcakes

I love chocolate and peanut butter together. It is the best mix in the world. When I eat a candy bar, I always look for the orange wrapper first. That is why I had to make these cupcakes. They taste just like the candy but even better because they are soft and fresh from my oven. You will learn how to make a dark chocolate cake that stays moist and a frosting that is fluffy like a cloud.

These cupcakes are great for birthdays or just a rainy Tuesday. My friends always ask for the recipe when I bring them to a party. They look fancy but they are actually very easy to bake. I will show you every step so you can make them at home today. Kids love to help with the candy part too!

Get your muffin tin ready and let us start baking these treats together.

The Secrets to Perfect Peanut Butter Cupcakes

Before we jump into the bowl, I want to talk about why this recipe works. A good cupcake needs to be light but strong enough to hold heavy frosting. Peanut butter is heavy, so we have to be smart about how we use it. I use cocoa powder for the cake because it makes a deep chocolate color that looks pretty against the tan frosting. It also makes the cake feel like a real treat.

One thing I learned the hard way is that not all peanut butter is the same. I once tried to use the natural kind that you have to stir. It was a big mess! The oil separated and made the frosting runny. For this recipe, stick to the creamy kind that stays smooth in the jar. It makes the texture perfect every single time. Let us look at what you need to get from the store.

What You Need to Buy

To make these cupcakes, you do not need any weird stuff. Most of these things are likely in your pantry right now. You will need flour, sugar, and unsweetened cocoa powder for the base. Make sure your cocoa is fresh so it smells strong. You also need baking powder, baking soda, and a little bit of salt. Salt is important because it makes the chocolate taste stronger.

For the wet parts, grab some milk, vegetable oil, and a large egg. I like using oil instead of butter for the cake part. It keeps the cake very soft even if you put them in the fridge. You also need vanilla extract. For the star of the show, buy a bag of mini Reese’s Peanut Butter Cups. You will put some inside the cake and some on top for decoration. For the frosting, you need butter, more peanut butter, and powdered sugar. Don’t forget a splash of heavy cream to make it extra fluffy.

• 1.5 cups all-purpose flour
• 1 cup granulated sugar
• 0.5 cup unsweetened cocoa powder
• 1 tsp baking powder and 0.5 tsp baking soda
• 1 large egg (room temperature is best)
• 0.5 cup whole milk
• 0.25 cup vegetable oil
• 1 tsp vanilla extract
• 0.5 cup boiling water
• 12 mini Reese’s cups for the middle

Mixing the Chocolate Batter

Making the batter is the fun part. First, you mix all the dry things in a big bowl. Use a whisk to get rid of any lumps in the cocoa powder. If the cocoa has big chunks, the cake might have bitter spots. Once that is mixed, add the egg, milk, oil, and vanilla. Mix it until it looks thick and dark. It will smell like a chocolate factory in your kitchen already!

The secret step is the boiling water. I know it sounds weird to add hot water to cake batter, but trust me. It helps the cocoa powder bloom. This means the chocolate flavor gets way bigger. Pour the hot water in slowly and whisk gently. The batter will be very thin, but that is okay. Thin batter makes a very light and airy cupcake. IMO, this is the best way to make chocolate cake from scratch.

The Hidden Candy Surprise

This is the part that makes people go wow. Line your muffin tin with paper liners. I like using orange or brown ones to match the Reese’s theme. Fill each liner about halfway with the chocolate batter. Then, take a mini peanut butter cup and push it right into the middle of the batter. Do not push it all the way to the bottom, or it might stick to the paper. Just let it hover in the center.

Cover the candy with a little bit more batter. You want the cup to be hidden like a secret treasure. When people take a bite, they will find the melted chocolate and peanut butter inside. It is a great surprise! If you don’t have mini cups, you could use a big spoon of peanut butter instead, but the candy is much more fun. Just make sure you don’t overfill the liners. If they are too full, they will spill over the edges and make a mess.

Baking to Perfection

Put your cupcakes in the oven at 350 degrees. They usually take about 18 to 22 minutes to bake. You can tell they are done when you poke the top and it springs back up. You can also use a toothpick. Stick it in the side of the cake, not the middle where the candy is. If the toothpick comes out clean or with just a few crumbs, they are ready. My kitchen always smells amazing at this point.

One big mistake I used to make was trying to frost them too soon. If the cake is even a little bit warm, the peanut butter frosting will melt and slide right off. It will look like a sad puddle. Take the cupcakes out of the tin and let them sit on a wire rack. They need to be completely cool to the touch. This usually takes about an hour. Go watch a show or clean up the dishes while you wait.

Whisking Up the Best Peanut Butter Frosting

The frosting is where the real peanut butter flavor lives. It is salty, sweet, and very creamy. I use a lot of peanut butter in mine because I want people to know exactly what they are eating. This frosting is so good I sometimes just eat it with a spoon. Don’t tell anyone! You want to use a hand mixer or a stand mixer for this part. Doing it by hand is a huge workout and it won’t get as fluffy.

You start by beating the butter and peanut butter together. They should look like one smooth, light tan cream. Then you add the powdered sugar. Add the sugar slowly or it will fly everywhere and cover your face in white dust. I’ve done that before and it was not funny at the time! Once the sugar is in, add a little milk or cream to make it soft enough to pipe through a bag.

Getting the Right Texture

The texture of your frosting is very important. If it is too stiff, it will tear the top of your cupcake. If it is too soft, it won’t hold its shape. You want it to look like thick whipped cream. If it feels too hard, add one teaspoon of milk at a time. If it looks too runny, add a little more powdered sugar. It is easy to fix if you go slow.

I like to use creamy peanut butter for a smooth look. If you use crunchy peanut butter, the little nut pieces will get stuck in your piping tip. That can be very frustrating! If you really want crunch, you can sprinkle crushed peanuts on top at the end. This frosting stays good at room temperature for a while, but it is best if you keep the cupcakes in a cool spot so the butter stays firm.

How to Decorate Like a Pro

You don’t need to be a chef to make these look pretty. Use a piping bag with a big star tip. Start in the middle of the cupcake and move in a circle toward the edge. Then, swirl back toward the middle as you go up. It makes a tall tower of frosting that looks like it came from a bakery. If you don’t have a piping bag, you can use a plastic storage bag. Just snip off one corner and squeeze!

Once the frosting is on, put another mini Reese’s cup on the very top. You can also drizzle some melted chocolate over the frosting if you want to be extra fancy. I sometimes crush up some extra candies and sprinkle the dust over the top too. It makes them look very professional. FYI, these look great on a white plate because the colors really pop. People will think you spent all day on them.

Storing Your Tasty Treats

If you have leftovers, you need to store them right. These cupcakes stay fresh for about three days if you put them in an airtight container. You can leave them on the counter if your house is cool. If it is hot, the frosting might get too soft. In that case, put them in the fridge. Just remember to take them out 30 minutes before you want to eat them. Cold frosting doesn’t taste as good as room temperature frosting.

You can also freeze these! If you want to make them ahead of time, bake the cakes and freeze them without frosting. They stay good for a month in the freezer. When you are ready for a party, thaw them out and make the fresh frosting. This is a great way to save time. I usually make a double batch because they go so fast. Everyone loves peanut butter and chocolate, so they never last long at my house.

Other Ways to Make This

You can change this recipe to fit what you like. If you don’t like chocolate cake, you can use a yellow cake recipe instead. It still tastes great with the peanut butter. You can also use different candies. Try using the white chocolate Reese’s or the ones with pieces inside. There are so many kinds now! It is fun to try new things and see what tastes best.

This recipe also works as a big cake. If you don’t want to make 12 small cupcakes, you can pour the batter into two round cake pans. You will need to bake them longer, maybe about 30 minutes. Just layer the frosting and candies in the middle. It makes a very impressive birthday cake. My brother asked for this version last year and he loved it. It is very flexible and hard to mess up if you follow the steps.

Common Questions About Baking

Can I use natural peanut butter?

I do not suggest it. Natural peanut butter has too much oil. It will make the frosting separate and runny. Use a standard creamy brand for the best results.

How do I keep the cupcakes moist?

Using vegetable oil instead of butter keeps them soft. Also, do not overbake them. Take them out as soon as a toothpick comes out clean.

What if I don’t have a piping bag?

You can use a gallon-sized Ziploc bag. Put the frosting in and cut a small corner off. It works just like a real piping bag for a simple swirl!

Can I make these gluten-free?

Yes! Use a 1-to-1 gluten-free flour blend. Most other ingredients are already naturally gluten-free, but always check your labels to be safe.

Do I have to use boiling water?

You should. The hot water makes the cocoa powder bloom, which gives you a much richer chocolate flavor. It makes a big difference in the final taste.

Enjoy Your Peanut Butter Treats

I hope you have a blast making these Reese’s Peanut Butter Cupcakes. They are the perfect mix of sweet and salty. Everyone will love the hidden candy inside.
