What You Need to Make Kit Kat Cupcakes
For your convenience, I’ve included shop-able ad links to some of the products used to make this candy bar cupcake recipe. Disclosure policy available here.
- All-purpose flour
- Cocoa Powder — Unsweetened baking cocoa, not to be confused with hot cocoa mix.
- Baking soda AND baking powder
- Egg — Allow the egg to come to room temperature
- Buttermilk — Adds a subtle zip to the cupcakes!
- Warm coffee — You can use decaf if making for the family and you don’t want caffeine in the cupcakes!
- Vegetable oil — Or your favorite cooking oil
- Vanilla extract
- Butter — We recommend unsalted butter for baking, as we already included salt in the recipe itself.
- Powdered sugar
- Vanilla extract
- Heavy cream — You can also substitute with other types of milk, including non-dairy.
- Kit Kats — You’ll crush half of them to incorporate into the frosting, and use the other half to decorate the cupcakes.
Kitchen Supplies Used
- Muffin tin
- Cupcake liners
- Stand mixer — You can also use an electric hand mixer if that’s what you have at home. But if you’ve been eyeing a gorgeous KitchenAid mixer, check out the refurbished options! We bought ours refurbished and saved a ton of money!
- Frosting decorating bag — We love these reusable silicone piping bags because you can wash and use them over and over again. A star tip makes those gorgeous icing swirls that you see at fancy bakeries.
Why is there coffee in the cupcakes?
Believe it or not, you won’t really taste the coffee in the cupcakes!
Coffee is often used in baking to enhance chocolate flavor. So adding coffee to our candy bar cupcakes makes them taste even MORE rich and chocolate-y!
You can use regular or decay, but if making for kids I’d definitely recommend decaf, as caffeine does NOT cook out and will still be in the cupcakes!
Can I use other candy bars?
Sure! We made these with Kit Kats specifically, but you could use this same recipe to make Twix cupcakes, Hershey bar cupcakes, or a spectacular combination!
All you’d have to do is swap out the candy bars used!
Can I use boxed cake mix?
Yep! We provided a recipe to make chocolate cupcakes from scratch, however, if you want to save time you can absolutely use a boxed cake or cupcake mix.
When it comes to frosting, I’d still recommend making your own if possible, as homemade buttercream holds its shape much better than store-bought frosting.
How do I make them gluten free?
Here’s the tricky part…Kit Kats aren’t gluten free. So while you can totally swap gluten free all-purpose flour for the regular flour in this recipe, the candy bars themselves contain gluten.
One option would be to use a type of candy that is also gluten free, if you’re not stuck on Kit Kats.
