These brownie-cake hybrid treats turn ordinary boxed mixes into something extraordinary that'll taste like you made them from scratch. They've got just the right mix of cakey and fudgy texture with deep chocolate flavor you won't be able to put down. The smooth chocolate frosting on top makes these babies vanish super fast whenever they show up at my gatherings.
I whipped these up for my kid's birthday when I was running behind but still wanted to make something memorable. She told me they beat anything from fancy bakeries, and now everyone demands them at family get-togethers.

How To Make Chocolate Brownie Cupcakes
- Get Everything Ready:
- Heat your oven to 350°F and put paper liners in your muffin tin. Go for good quality liners so they won't stick and will keep their shape while baking.
- Create Your Batter:
- Dump both the cake mix and brownie mix into a big bowl. Add your room temperature eggs, pour in the water and oil. Stir everything for about two minutes, going in circles to work in some air and get rid of any lumps. You want your mix looking shiny and smooth.
- Pour Into Cups:
- Use an ice cream scoop or measuring cup to fill each liner about two-thirds full. This lets them rise without making a mess. Give the pan a light tap on the counter to pop any big air bubbles.
- Bake Them Up:
- Put the pan on the middle rack in your hot oven. Let them bake for 18 to 22 minutes, checking when you hit the minimum time. They're done when the tops bounce back a little when touched and a toothpick comes out with a few crumbs but not wet batter.
- Let Them Cool:
- Keep the cupcakes in the pan for 5 minutes after baking. This helps them firm up without getting damp. Then move them to a cooling rack for at least half an hour before adding frosting. They must be totally cool or your topping will just slide off.
- Make Your Frosting:
- Put softened butter in your mixer bowl. Add in the cocoa, honey, vanilla, and powdered sugar. Mix slowly for about half a minute until things start coming together. It'll look dry and chunky at first.
- Get The Right Texture:
- While mixing on low, pour in heavy cream one spoon at a time. Watch as your frosting changes from crumbly to silky smooth. Stop adding cream once it's easy to spread but still holds its shape. You might need less cream on humid days or more when it's dry.
- Top And Enjoy:
- Once cupcakes are completely cool, spread on frosting with a knife or pipe it on. Start from the edges and work your way to the middle in a spiral. Eat right away or keep covered at room temp.

Adding honey to the frosting was a happy accident when I ran out of corn syrup one time. Now I always make my chocolate frosting this way. It gives a little something extra that makes everyone beg for the recipe.
Storage Solutions
These treats stay amazingly moist when you keep them in a sealed container at room temperature for up to four days. If you want to make them further ahead, freeze the unfrosted cupcakes by wrapping each one in plastic, then putting them in a freezer bag for up to three months. Just let them thaw naturally before adding frosting. You can also make the frosting a week early and keep it in the fridge. Just warm it up and give it a quick whip before using.
Creative Variations
These chocolate treats are awesome as they are, but you can easily switch things up. Try adding some espresso powder to the mix for coffee-flavored ones, or throw in some mini chocolate chips for extra bits of chocolate. For the topping, you can mix in some peanut butter or swap the vanilla for mint extract during Christmas time. My family goes crazy when I scoop out the middle of each cupcake and drop in some salted caramel before putting on the frosting.

Serving Suggestions
You can serve these at pretty much any event. For kids' parties, add some bright sprinkles or little chocolate chips on top. For fancy dinners, pipe the frosting up high and add some chocolate curls or a light dusting of cocoa. They go great with coffee, milk, or even red wine for the grown-ups. I like to serve them a bit cool in summer and room temp in winter for the best texture experience.
