Why You’ll Love These

Easy: This is a simple recipe with no complicated steps. Even the frosting and garnishes are easy to add on top, so you don’t have to be an experienced baker to get these just right! Also you don’t need to buy typical cake ingredients like flour, baking soda or baking powder, as the cake mix has this covered already.
Delicious: You can tell just by looking at these chocolate cupcakes how tasty they’re going to be with their chocolate chips and chocolate flavor, as well as the vanilla extract. They’re light, fluffy and so good!
Customizable: Feel free to use a different flavor of boxed cake mix, a different frosting in place of the peanut butter buttercream or even different decorations on top.

Key Ingredients for Chocolate Kitchen Sink Cupcakes

A complete list of ingredients and amounts can be found in the recipe card below.

Devil’s food chocolate cake mix: The basis of the recipe. Swap for another flavor if you want or even make your own chocolate cake batter.
Chocolate instant pudding: Another shortcut ingredient. Again, you can sub another flavor. Don’t use regular (not instant) pudding mix – it won’t work the same.
Greek yogurt: For adding moisture and a tangy flavor. Sour cream works too.
Peanut butter: Don’t use the 100% natural peanut butter because it’s too oily.
Unsalted butter: To get the frosting creamy. If you only have salted, that’s fine – just omit the sea salt.
Powdered sugar: To sweeten the frosting. Don’t use regular sugar, or else it will be grainy.
Vanilla extract: Contrasts with the chocolate flavor. Don’t use vanilla essence (which is synthetic).
Heavy cream: To add creaminess to the frosting. If your frosting is too thick, you can add a splash extra.

A delectable concoction of chocolate and pretzel flavors come together in this irresistible cookie recipe.

Substitutions and Variations

Greek yogurt: Replace this ingredient with sour cream if you like.
Unsalted butter: You can use salted butter but if you do then don’t add any extra salt.
Gluten free version: Sub a gluten free cake mix for the regular one and use a gluten free pudding mix (such as the Simply Delish brand) if you want to make this completely gluten free.

Serving Suggestions

How to Store These Game Day Cupcakes

Store: Keep these in an airtight container in the refrigerator for up to 3 days. The toppings will soften but the cupcakes will still taste good!
Freeze: You can freeze these unfrosted if you like. To do so, put them in a freezer-safe container or Ziploc bag and use within 3 months.
Thaw: Thaw as many as you need in the refrigerator overnight and then frost and decorate.

Top Tips

Let them cool: If you try to frost the cupcakes before they’re cool, the frosting will melt and become messy, so allow the cupcakes to cool completely first!
Change the flavor: If you want to swap the cake mix and instant pudding mix for different flavors, go ahead – you might end up discovering a brand new favorite cupcake recipe!
Check when they’re done: As ovens vary, you will need to check your cupcakes for doneness with a toothpick. They typically take anywhere from 15 to 18 minutes to cook through.

Easy Chocolate Cupcakes Recipe FAQs

Why do some people call these chocolate cupcakes a kitchen sink cupcakes recipe?

This comes from the phrase everything but the kitchen sink meaning all kinds of delicious add-ins are in the cupcake batter – peanut butter, chocolate, vanilla, instant pudding mix… pretty much everything except the kitchen sink!

Do you need a piping bag to frost them?

If you’re comfortable piping frosting using a piping bag, go ahead. If you don’t have one or you don’t want to use one, simply use a butter knife to spread the frosting on top before adding the toppings.
