INSTRUCTIONS

Step 1:

Pop the oven on at 350°F (175°C). Toss liners in your cupcake tray.

Step 2:

Mix salt, baking soda, flour, and the cocoa together in a bowl.

Step 3:

In another bowl, blend sugar, oil, the eggs, and some vanilla. Swap in the dry stuff, pouring in milk here and there until smooth.

Step 4:

Spoon the batter into your prepared cups, about two-thirds full. Bake for 18-20 mins. Let them get totally cool before moving on.

Step 5:

Whip up the filling: creamy peanut butter, powdered sugar, and milk. Scoop a hole in each cupcake and stuff it in.

Step 6:

Beat the butter with peanut butter until fluffy. Add powdered sugar, milk, and vanilla. Swirl the frosting on top of each cupcake.

Serving and Storage Tips

• If you want the middle all gooey, warm 'em a tiny bit before serving. That peanut butter will be extra melted.
• Keep them in a sealed container at room temp for a couple days. Fridge works too if you want 'em to last longer.

Helpful Notes

• Wait until the cupcakes are cool before filling and icing or you’ll have a big mess.
• Sprinkle a pinch of sea salt on the frosting for a nice salty kick.

Tips from Well-Known Chefs

• A piping bag makes stuffing the cupcakes super easy and way less messy.

Chocolate and Peanut Butter Dream

Every bite is packed with chocolate and peanut butter magic. You’ll love the smooth middle—the surprise inside is the best part. These are spot-on for birthdays, celebrations, or just because you want something awesome.

FAQs

Can I freeze these cupcakes?

Sure! Just skip the frosting first. Wrap each one well in plastic and freeze in a bag for three months.

What can I use instead of vegetable oil?

Try melted coconut oil or canola oil for a change. Flavor might be a bit different, but it totally works.

How do I prevent the peanut butter filling from leaking?

Make sure you get the filling deep in the cupcake and cover it all up with frosting.

Can I use natural peanut butter for this?

It's better to stick to regular creamy peanut butter. Natural kinds split and don't mix up as well for this.
