Ingredients for Kit Kat Candy Bar
Gather these items:
- 1 1/2 cups All-Purpose Flour
- 1 cup Sugar
- 1/3 cup Cocoa Powder
- 1 teaspoon Baking Soda
- 1/2 teaspoon Baking Powder
- 1/2 teaspoon Salt
- 1 large Egg, room temperature
- 1/2 cup Buttermilk, room temperature
- 1/2 cup Coffee, hot
- 1/4 cup Vegetable Oil
- 1 1/2 teaspoon Vanilla Extract
- 12 Kit Kats, half crushed, half cut into quarters
- 1 cup Butter, room temperature
- 4 cups Powdered Sugar
- 2 teaspoons Vanilla Extract
- 2 Tablespoons Heavy Cream

How to Make Kit Kat Candy Bar Step-by-Step
- Step 1: Preheat your oven to 350°F and line a muffin tin with cupcake liners to get ready for baking.
- Step 2: Place half of the Kit Kat bars into a sealed Ziploc bag and crush them using a rolling pin; these will be mixed into the batter for delightful chunks of chocolate.
- Step 3: In a large bowl, sift together the flour, sugar, cocoa powder, baking soda, baking powder, and salt to combine the dry elements evenly.
- Step 4: In a separate bowl, whisk together the egg, buttermilk, hot coffee, vegetable oil, and vanilla extract until smooth and well blended.
- Step 5: Gradually add the dry ingredients to the wet ingredients using a mixer set on medium speed; mix for about 2 minutes and scrape down the sides as needed to ensure thorough incorporation.
- Step 6: Gently fold the crushed Kit Kat pieces into the batter, distributing them evenly without overmixing.
- Step 7: Divide the batter evenly among the cupcake liners, filling each about two-thirds full.
- Step 8: Bake the cupcakes for 13 minutes or until a toothpick inserted into the center comes out clean. Remove from the oven and let them cool completely before frosting.
- Step 9: Using a stand mixer with a paddle attachment, beat the softened butter on medium speed until light and creamy, about 2–3 minutes.
- Step 10: Add powdered sugar, vanilla extract, and heavy cream to the butter and mix on low speed until combined and smooth.
- Step 11: Add the crushed Kit Kat pieces to the frosting and increase the mixer speed to medium-high, whipping the frosting for 3–4 minutes until fluffy.
- Step 12: Transfer the frosting to a decorating bag and pipe it generously onto the cooled cupcakes.
- Step 13: Top each cupcake with quarters of Kit Kat bars and drizzle with fudge sauce if desired for an extra special look and flavor.
