CakeFrosting
  • 2 cups all-purpose flour
  • 2 cups granulated sugar
  • 1 tsp baking powder
  • 1 tsp baking soda
  • 1/4 tsp kosher salt
  • 1 cup (2 sticks) salted butter
  • 1/2 cup unsweetened cocoa powder
  • 1 cup boiling water
  • 1/2 cup whole milk
  • 2 tsp peppermint extract
  • 2 large eggs
  • 1 lb. powdered sugar
  • 1 cup (2 sticks) salted butter, at room temperature
  • 2 tbsp whole milk
  • 1 tbsp vanilla extract
  • 1 cup crushed candy canes or peppermint candies, for decoration

Step-by-Step Instructions

Let’s break down the process so you can recreate this impressive sheet cake with confidence:

1. Prep the Pan

  • Preheat your oven to 350°F (175°C).
  • Line a 13-by-18-inch rimmed baking sheet (or jelly roll pan) with parchment paper, ensuring seamless removal after baking.

2. Mix Dry Ingredients

  • In a large mixing bowl, whisk together flour, granulated sugar, baking powder, baking soda, and salt until evenly combined.

3. Prepare Chocolate Mixture

  • In a small saucepan over medium-low heat, melt the salted butter and cocoa powder together, whisking until smooth (about 2 minutes).
  • Cautiously add boiling water to the mixture and allow it to bubble briefly, then remove from heat.
  • Pour this warm chocolate mixture into the bowl with the dry ingredients and stir until smooth.
  • Let the batter cool for 5 minutes.

4. Combine Wet Ingredients

  • In a separate bowl, whisk together whole milk, peppermint extract, and eggs until blended.
  • Gently stir this milk mixture into the cooled chocolate batter until fully incorporated and smooth.

5. Bake the Cake

  • Pour the batter into your prepared pan and smooth out the top evenly.
  • Tap the pan on the counter a few times to remove air bubbles.
  • Bake for about 20 minutes, or until a toothpick inserted in the center comes out clean and the cake springs back to the touch.
  • Let the cake cool briefly in the pan.

6. Make Peppermint Frosting

  • In a large bowl, use a mixer on low speed to beat together powdered sugar, butter, milk, and vanilla extract until smooth (2–3 minutes).
  • Increase mixer speed to medium and beat until the frosting is light and fluffy (an additional 2 minutes).

7. Frost and Decorate

  • Spread the frosting evenly over the slightly cooled cake using an offset spatula or the back of a spoon.
  • Let the frosting set for about 15 minutes.
  • For a decorative finish: Lay two strips of parchment diagonally across the cake to act as stencils.
  • Sprinkle crushed candy canes or peppermint candies in between the parchment lines to create striking, festive stripes. Shift the parchment as you go for even lines.

Tips for Success

  • Room Temperature Ingredients: Ensure butter is at room temperature for a silky frosting texture and even mixing.
  • Peppermint Extract: Measure carefully—peppermint extract can overpower easily, so stick precisely to the suggested amount.
  • Don’t Overbake: Start checking the cake at 18 minutes to prevent it from drying out; the cake should be just set and springy.
  • Use Fresh Candy: Crush candy canes or peppermint candies just before decorating for the brightest color and crunch.

Frequently Asked Questions (FAQs)

Q: Can I make this cake ahead of time?

A: Yes! You can bake the sheet cake a day in advance, wrap it tightly once cooled, and frost it before serving. The frosted cake will also keep well covered at room temperature for up to two days.

Q: Can I freeze the cake?

A: Absolutely. If you plan on freezing, bake and cool the cake completely, wrap well, and freeze without frosting for up to 2 months. Thaw at room temperature before frosting and decorating.

Q: How do I get sharp, clean stripes with the peppermint candy?

A: Use two strips of parchment paper laid diagonally across the cake as a stencil, then sprinkle the crushed candy between. Carefully lift and reposition the strips as you go for crisp, straight lines.

Q: What’s the best way to crush the candy canes?

A: Place unwrapped candy canes or peppermint candies in a heavy-duty plastic bag, seal, and crush with a rolling pin or meat mallet until you get small pieces (but not dust). Aim for a mix of shards and small bits for the best texture.

Q: Can I adjust the intensity of mint flavor?

A: Yes, the peppermint intensity is easily customized. Use less extract for a subtler flavor, or add a bit more (a quarter teaspoon at a time) if you like a stronger mint hit.

Serving and Storage Suggestions

  • Perfect for Parties: This sheet cake serves about 24 guests, making it ideal for gatherings big and small.
  • Serving Tip: Cut into squares or rectangles for easy portioning. Pair with a hot mug of cocoa or coffee for extra holiday cheer.
  • Storage: Store covered at room temperature for up to two days, or refrigerate if your kitchen is very warm.
  • Leftovers: Leftover cake can be stored in an airtight container. The cake retains its moistness and flavor for several days.

Variations & Customizations

  • Gluten-Free Version: Substitute your favorite cup-for-cup gluten-free flour blend.
  • Dairy-Free: Use vegan butter and plant-based milk for both cake and frosting.
  • Extra Chocolate: Stir in a cup of mini chocolate chips into the batter for bursts of chocolate in every bite.
  • Festive Sprinkles: For more color, add festive holiday sprinkles along with or instead of crushed candy canes.
  • Different Extracts: Swap peppermint for orange or almond extract for a new flavor profile.

Ideas for Holiday Dessert Tables

  • Pairing: This cake pairs beautifully with other seasonal treats, such as red velvet desserts, Italian Christmas cookies, or a no-bake cheesecake.
  • Presentation: Serve on a large tray or cake stand for maximum effect. Garnish the edges with extra whole candy canes for a stunning centerpiece.
  • Make It a Tradition: Its striking appearance and reliable flavor make this a standout dessert to enjoy year after year.

Expert Baking Tips for Sheet Cakes

  • Uniform Baking: A rimmed baking sheet (13×18 inches) ensures even baking; avoid using significantly smaller or larger pans, which can affect baking time and texture.
  • Parchment Paper: Lining the pan prevents sticking and makes for easier removal and neater slicing.
  • Cooling: Let the cake cool slightly before adding frosting, but don’t wait until it’s cold—the frosting will spread more smoothly on a barely-warm cake.
  • Baking in Advance: If you need to prep ahead, bake and freeze the unfrosted cake, then make the frosting fresh before serving for the best flavors and texture.

More Chocolate-Peppermint Treats to Try

  • Peppermint Patty Cake: Infuse cakes with mini peppermint patties for extra bursts of cool mint and gooey chocolate.
  • Peppermint Fudge: Create a rich fudge with a layer of peppermint swirl.
  • No-Bake Peppermint Desserts: Save time with quick recipes like peppermint bark, icebox cakes, or layered trifles.

Frequently Asked Questions (Quick Reference)

Q: Can I make this recipe nut-free?

A: Yes, this recipe is naturally nut-free. Always double-check your ingredient labels for cross-contamination if you have serious allergies.

Q: Can I double the recipe for a larger crowd?

A: Doubling works best when using two pans rather than one oversized pan, to ensure the cake bakes evenly and thoroughly.

Q: What if I don’t have peppermint extract?

A: Substitute with a smaller amount of pure mint extract, or omit for a more classic chocolate flavor. Crushed candy canes alone will still give a mild minty taste.
