Moist Chocolate Cupcakes

Featured in Irresistible Desserts & Treats.

If you’re into chocolate, these cupcakes are for you! The thin batter—thanks to hot water—yields incredibly moist results and cranks up that cocoa flavor. Combine that with quality cocoa powder for a heavenly taste. Whipped chocolate buttercream balances sweetness with chocolate richness, and they taste even better overnight. They’re perfect for any event or just as a go-to snack made with simple pantry ingredients.

Dive into chocolate heaven with these indulgent homemade treats. After countless kitchen trials, I've nailed the sweet spot between intense cocoa flavor and soft, juicy texture. Carefully selected ingredients come together in a dessert that puts store-bought versions to shame.

Everyone raves about these little cakes thanks to their deep chocolate punch and dreamy consistency. The magic happens when cocoa meets cultured buttermilk, creating that unforgettable richness you'll crave again and again.

Must-Have Components

  • All-Purpose Flour: Pick unbleached and measure it right for that perfect structure you want.
  • Granulated Sugar: The small crystals melt smoothly, giving just the right sweetness.
  • Cocoa Powder: Go for plain unsweetened, and don't skip sifting to keep your mix lump-free.
  • Leaveners: Only use fresh baking soda and powder to make sure they rise beautifully.
  • Neutral Oil: This keeps everything moist without changing the taste.
  • Fresh Eggs: Let them sit out before using for better mixing and fluffier results.
  • Buttermilk: The real cultured stuff makes all the difference for softness and taste.

Step-By-Step Process

Getting Ready:
Heat oven to 350°F with rack in the middle. Take cold stuff out early to warm up. Line your muffin tin and give the liners a quick spray.
Dry Mix:
Grab 1¾ cups flour, 1½ cups sugar, ¾ cup cocoa, 1½ teaspoons baking soda, 1 teaspoon baking powder, ½ teaspoon salt and whisk them for half a minute.
Liquid Mix:
In another bowl, whisk ½ cup oil, 2 eggs, 1 cup buttermilk, 2 teaspoons vanilla until they're well mixed and a bit fluffy.
Putting Together:
Dump wet stuff into dry stuff. Stir gently just until mixed. Pour in ½ cup really hot water, mix till smooth. Your mix will look runny.
Cooking:
Fill each cup about ¾ full. Bake 18-22 minutes until a toothpick comes out with moist bits. Turn the pan around halfway. Let them sit 5 minutes before moving to a cooling rack.

Old-school bakers have always known the secret: real buttermilk isn't just nice to have, it's absolutely needed for that melt-in-your-mouth softness that makes these treats so special.

Serving Suggestions

Show them off on a stack-style plate for wow factor. Serve them not too cold or hot. Pair with cold milk or fresh coffee. Add fresh berries or shiny sprinkles for fancy times.

Tasty Twists

Make these even better by swapping water for hot coffee to boost the chocolate kick, and throw in some espresso powder for extra richness. Toss in tiny chocolate bits for a fun texture change, then add swirls of raspberry jam for a fruity surprise. Finish with smooth peanut butter topping that perfectly balances the bold chocolate base.

Keeping Fresh

Store topped treats in an airtight box on the counter for 3 days. Freeze plain ones up to 3 months. Let them sit out 2 hours before adding topping. You can make your topping 3 days ahead and keep it in the fridge.

Frequently Asked Questions

→ Why is the batter so runny?
That’s all part of the plan! The hot water brings out the chocolate’s best flavor while creating a tender and moist texture in the finished cupcake.
→ Can I replace buttermilk with something else?
For sure! Just mix a cup of milk with a tablespoon of lemon juice or vinegar. Let it sit for a few minutes, and once it curdles, you’re good to go.
→ What’s the best way to store these cupcakes?
Put frosted ones in a sealed container, and they’ll last three days at room temperature. They taste better next day! For longer storage, refrigerate for up to a week or freeze and thaw before enjoying.
→ Can these cupcakes go in the freezer?
Definitely! You can freeze the unfrosted cupcakes for up to three months in an airtight container. Thaw before adding frosting, or freeze already-frosted ones, but the frosting might not look perfect after thawing.
→ How do these cupcakes stay so moist?
It’s a mix of things—like using oil for longer-lasting moisture, buttermilk for soft crumbs, and hot water for a thin batter that bakes into rich, moist perfection while boosting the chocolate flavor.

Ingredients

→ Chocolate Cupcakes

01 1 cup of very hot water
02 1 1/2 teaspoons vanilla extract
03 1 cup of buttermilk
04 1/2 cup of coconut or canola oil
05 2 large eggs
06 1 teaspoon salt
07 2 teaspoons baking soda
08 1 teaspoon baking powder
09 3/4 cup of dark cocoa powder
10 1 3/4 cups granulated sugar
11 1 3/4 cups all-purpose flour

→ Chocolate Buttercream

12 3 1/2 cups powdered sugar
13 1 cup of butter, room temperature
14 3/4 cup cocoa powder
15 2-3 tablespoons of cream, milk, or half-and-half

→ Garnish

16 Sprinkles, mini chocolate chips, or shavings

Instructions

Step 01

Fire up your oven to 350°F (175°C) and shift the rack to the center spot.

Step 02

Combine the sugar, cocoa, salt, flour, baking soda, and baking powder in a big mixing bowl. If you’ve got a sifter, it makes blending easier.

Step 03

In a second bowl, whisk the buttermilk, vanilla, eggs, and oil together till smooth. A minute of mixing is plenty.

Step 04

Add the dry mix to the wet one bit by bit while stirring lightly. When that’s done, slowly mix in the hot water. The batter’s supposed to be runny—that’s how they stay moist!

Step 05

Line up the cupcake tins with baking liners and lightly spray them with nonstick cooking mist. Fill each liner about 3/4 of the way.

Step 06

Pop the trays into the preheated oven and let them bake for about 18 to 22 minutes. You’ll know they’re ready when a clean toothpick comes out after poking the middle.

Step 07

Pull the cupcakes out of the tins and let them cool all the way down before adding any frosting.

Step 08

While the cupcakes cool, cream the butter and cocoa together until smooth. Slowly add powdered sugar, throwing in a splash of cream here and there. Keep whipping until it’s fluffy—and adjust with extra cream if spreading feels tough.

Step 09

Spread or pipe the chocolate buttercream over cooled cupcakes. Sprinkle on some chips, curls, or whatever toppings you love.

Notes

  1. For extra flavor, store these covered overnight before serving.
  2. Adding boiling water to the batter makes them incredibly tender and moist.
