Ingredients You'll Need
Gathering the right ingredients is the first step to creating these delightful cupcakes. Each component is simple but important, adding layers of flavor, texture, and that wow factor we all crave. From the rich cocoa powder that gives the cake its deep chocolate taste to the caramel sauce that elevates the buttercream to pure magic, these ingredients work together to create something truly special.
- 1 cup + 2 tablespoons all purpose flour: Provides the perfect structure to keep the cupcakes moist yet fluffy.
- ½ cup cocoa powder: Delivers a rich, chocolaty base that complements the Kit Kat wafers beautifully.
- ½ teaspoon baking soda: Helps the cupcakes rise to tender perfection.
- ⅛ teaspoon salt: Balances sweetness and enhances chocolate flavor.
- ¾ cup + 2 tablespoons granulated sugar: Sweetens the batter while contributing to a tender crumb.
- ¼ cup vegetable oil: Keeps the cupcakes moist and soft.
- 1 egg: Binds ingredients and adds richness to the texture.
- 1 teaspoon vanilla extract: Adds warmth and depth to the flavor profile.
- ⅔ cup buttermilk: Creates a tangy contrast and tenderness in the crumb.
- 6 fun-sized Kit Kat bars, broken into single wafers (12 wafers total): The star ingredient that surprises with crunchy pockets inside the cupcake.
- ½ cup (1 stick) unsalted butter, softened (for frosting): The creamy base for the caramel buttercream frosting.
- 1 ½ cups powdered sugar: Sweetens and thickens the frosting to the perfect consistency.
- Pinch of salt: Cuts through sweetness and highlights the caramel’s richness.
- ¼ cup caramel sauce (homemade or store-bought): Infuses the frosting with irresistible sweetness and a buttery finish.
How to Make Kit Kat Cupcakes with Caramel Buttercream Frosting Recipe
Step 1: Prepare Your Oven and Dry Ingredients
Preheat your oven to 350 degrees Fahrenheit and line a cupcake pan with 12 paper liners. Next, whisk together the flour, cocoa powder, baking soda, and salt in a medium bowl to ensure even distribution. This mix will give the cupcakes that classic chocolate flavor with the perfect lift.
Step 2: Combine Sugar, Oil, and Wet Ingredients
In a large bowl, beat the granulated sugar and vegetable oil together until smooth and slightly glossy. Add in the egg and vanilla extract, beating until fully incorporated. This creates a smooth, rich base that locks in moisture.
Step 3: Alternate Adding Dry Ingredients and Buttermilk
Gradually add the flour mixture and buttermilk alternately to the wet ingredients—flour in three parts and buttermilk in two. This method prevents overmixing and keeps the batter light, leading to tender cupcakes.
Step 4: Assemble Cupcakes with Kit Kat Wafers
Scoop a small amount of batter into each cupcake liner to cover the bottom. Cut one Kit Kat wafer in half and place both halves flat on top of this batter layer. Then, cover with more batter until the liner is about two-thirds full. This layering ensures the Kit Kat wafers bake into hidden, crunchy pockets inside.
Step 5: Bake and Cool
Bake for 16 to 18 minutes or until a toothpick inserted near the Kit Kat comes out with a few moist crumbs but not wet batter. The tops will likely sink just a bit, but that's perfect—cool the cupcakes completely before frosting to keep everything neat.
Step 6: Make the Caramel Buttercream Frosting
Beat softened butter, powdered sugar, and a pinch of salt until smooth and creamy. Pour in the caramel sauce and continue beating until the frosting is light and fluffy. This caramel buttercream frosting is what truly elevates the cupcakes, adding a luscious, silky finish.
Step 7: Frost and Garnish
Pipe or spread the caramel buttercream over each cooled cupcake. Take the remaining Kit Kat wafers, cut each in half, and press them cut side down into the frosting to create a stunning and crunchy garnish.
How to Serve Kit Kat Cupcakes with Caramel Buttercream Frosting Recipe
Garnishes
Besides the Kit Kat wafer garnish, you can sprinkle flaky sea salt on top of the frosting for a delightful salty-sweet contrast, or add a drizzle of warm caramel sauce for extra decadence. These simple touches add flair and enhance the caramel flavor beautifully.
Side Dishes
Pair these cupcakes with a scoop of vanilla ice cream or a dollop of whipped cream to create a comforting dessert experience. For an afternoon treat, a cup of strong coffee or a rich hot chocolate complements the chocolate and caramel profile perfectly.
Creative Ways to Present
Arrange the cupcakes on a tiered cake stand for festive occasions, or place each cupcake in a decorative cupcake wrapper with a little ribbon tied around for gifting. You could even create mini cupcake cones by placing frosting-topped cupcakes inside mini waffle cones—a playful and unique presentation.
Make Ahead and Storage
Storing Leftovers
Store leftover cupcakes in an airtight container at room temperature for up to two days to keep them fresh and moist. If your kitchen is warm, the fridge is an option but let them come back to room temperature before serving for optimal flavor.
Freezing
You can freeze unfrosted cupcakes by wrapping each individually in plastic wrap and placing them in a freezer-safe container for up to three months. Thaw completely at room temperature before frosting. Frosted cupcakes can also be frozen briefly but are best enjoyed fresh.
Reheating
To refresh cupcakes after refrigeration or freezing, warm them gently in the microwave for about 10 seconds. This softens the cake and brings back that freshly-baked warmth without melting the frosting.
FAQs
Can I use chocolate chips instead of Kit Kat wafers?
Absolutely! While Kit Kat wafers provide a unique crunch and the iconic layered texture, chocolate chips will melt into pockets of gooey chocolate. Both are delicious, but the experience will vary slightly.
Is there a substitute for buttermilk?
Yes! If you don’t have buttermilk on hand, mix ⅔ cup of milk with 1 tablespoon of lemon juice or white vinegar, let it sit for 5 minutes, and use it as a substitute. This keeps the cupcakes tender and adds that slight tang.
Can I make the caramel buttercream frosting ahead of time?
You can prepare the frosting a day in advance and keep it refrigerated in an airtight container. Before using, bring it back to room temperature and whip a bit to restore its creamy texture.
How do I prevent the cupcakes from sinking?
Sinking tops usually result from opening the oven door too early or underbaking. Be sure to wait until the cupcakes are set before checking, and avoid opening the oven frequently during baking.
Can these cupcakes be made gluten-free?
Yes, by substituting all-purpose flour with a gluten-free flour blend designed for baking, you can enjoy these cupcakes gluten-free. Just ensure your other ingredients like baking powder and caramel sauce are also gluten-free.
Final Thoughts
Trust me, once you try this Kit Kat Cupcakes with Caramel Buttercream Frosting Recipe, you’ll wonder why you ever settled for ordinary cupcakes.
