Ingredient List

For the Cupcakes

• 1 cup (125g) all-purpose flour
• ¾ cup (75g) unsweetened cocoa powder
• 1 tsp baking powder
• ½ tsp baking soda
• ¼ tsp salt
• ½ cup (115g) unsalted butter, softened
• 1 cup (200g) granulated sugar
• 2 large eggs
• 1 tsp vanilla extract
• ½ cup (120ml) buttermilk
• ½ cup (120ml) hot water

For the Mint Frosting

• 1 cup (230g) unsalted butter, softened
• 3–4 cups (360–480g) powdered sugar
• 2–3 tbsp heavy cream or milk
• 1 tsp peppermint extract
• Green gel food coloring (optional, for festive St Patrick’s day dessert vibes)
• Chocolate chips or shavings for topping (optional)

Ingredient Notes

• I always use high-quality cocoa powder—it makes the chocolate flavor so rich and satisfying.
• Don’t skip the buttermilk! It keeps these easy mint chocolate cupcakes extra moist and tender.
• For the frosting, I love using real peppermint extract instead of artificial flavoring—it gives such a fresh, natural taste.
• Green gel food coloring is optional, but it really makes these cupcakes perfect for a St Patrick’s day dessert display.
• Chocolate chips or shavings on top? Totally optional, but they add that little extra wow factor for chocolate birthday cupcakes.

Kitchen Equipment Needed

• Mixing bowls – For combining wet and dry ingredients. I love using glass bowls because you can see everything clearly.
• Electric mixer or stand mixer – Makes the frosting super smooth and fluffy. Hand mixers work too if that’s what you have.
• Measuring cups and spoons – Accurate measurements make all the difference in baking. My favorite are stainless steel ones—they last forever!
• Cupcake pan – For perfectly shaped cupcakes. Non-stick pans make removal so much easier.
• Cupcake liners – Keeps cupcakes neat and easy to serve. I always use parchment paper liners for a clean look.
• Spatula – For folding ingredients and scraping the bowl. Silicone ones are my go-to.
• Piping bag + tip – Optional, but perfect for creating pretty swirls of mint frosting.

Instructions

Step 1: Preheat and Prep

1. Preheat your oven to 350°F (175°C).
2. Line a 12-cup cupcake pan with cupcake liners. I like using parchment paper liners—they make cleanup so much easier and the cupcakes slide out perfectly.
3. Lightly spray the liners with non-stick cooking spray for extra insurance against sticking.

Pro Tip: Make sure your oven is fully preheated before baking—this helps the cupcakes rise evenly.

Step 2: Mix the Dry Ingredients

1. In a medium bowl, sift together the flour, cocoa powder, baking powder, baking soda, and salt.
2. Whisk everything until fully combined.

Pro Tip: Sifting the cocoa powder and flour together helps prevent lumps and gives the cupcakes a smoother texture.

Step 3: Cream Butter and Sugar

1. In a large mixing bowl, beat the softened butter and sugar together until light and fluffy—about 2–3 minutes with an electric mixer.
2. Add the eggs one at a time, mixing well after each addition.
3. Stir in the vanilla extract.

Pro Tip: Don’t rush this step! Properly creamed butter and sugar gives the cupcakes a tender, airy crumb.

Step 4: Combine Wet and Dry Ingredients

1. Gradually add the dry ingredients to the butter mixture in three parts, alternating with the buttermilk in two parts.
2. Begin and end with the dry ingredients, mixing gently to avoid overmixing.
3. Slowly stir in the hot water until fully combined—this makes the batter silky and smooth.

Pro Tip: Whisk continuously when adding hot water to prevent any lumps and ensure a glossy, smooth batter.

Step 5: Fill Cupcake Liners

1. Spoon the batter evenly into the prepared liners, filling each about 2/3 full.
2. Gently tap the pan on the counter to remove any air bubbles.

Pro Tip: Using an ice cream scoop ensures all cupcakes are the same size and bake evenly.

Step 6: Bake

1. Bake in the preheated oven for 18–22 minutes, or until a toothpick inserted in the center comes out clean.
2. Let the cupcakes cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.

Pro Tip: Avoid frosting the cupcakes while they’re warm—this can cause the frosting to melt and slide off.

Step 7: Make the Mint Frosting

1. Beat the softened butter on medium speed until creamy.
2. Gradually add the powdered sugar, 1 cup at a time, mixing on low speed at first.
3. Add the peppermint extract, heavy cream (or milk), and green gel food coloring. Beat on high until light, fluffy, and smooth.

Pro Tip: Taste the frosting before coloring—you can adjust the mint to your preference.

Step 8: Frost the Cupcakes

1. Transfer the frosting into a piping bag fitted with your favorite tip.
2. Pipe generous swirls of frosting onto the cooled cupcakes.
3. Optional: sprinkle chocolate shavings or chips on top for extra chocolatey goodness.

Tips and Tricks for Success

• Room temperature ingredients – Make sure butter, eggs, and buttermilk are at room temperature for smoother batter and fluffier cupcakes.
• Don’t overmix – When combining wet and dry ingredients, mix just until combined to keep cupcakes tender.
• Check oven temperature – Oven temperatures can vary; use a toothpick to test doneness rather than relying strictly on time.
• Cool completely before frosting – Warm cupcakes can cause frosting to melt and lose shape.
• Use a piping bag – It’s easier and makes your cupcakes look extra polished. You can swirl the frosting in any fun pattern you like!

Ingredient Substitutions and Variations

• Butter substitute – Swap butter for coconut oil or a plant-based margarine for a dairy-free version.
• Milk substitute – Use almond, oat, or soy milk instead of heavy cream or regular milk in the frosting.
• Mint flavor alternative – If peppermint extract is too strong, try a few drops of mint chocolate liqueur or natural mint essence.
• Chocolate variations – Mix in mini chocolate chips into the cupcake batter for extra chocolatey bites.
• Festive twist – Add a sprinkle of green sanding sugar on top of the frosting for St Patrick’s day dessert flair.
• Flavor swap – Turn these into chocolate birthday cupcakes by adding colorful sprinkles inside the batter for a fun surprise.

Serving Suggestions

• I love serving these mint chocolate cupcakes with a hot cup of cocoa—it doubles down on the chocolatey goodness and keeps things cozy.
• Pair them with fresh berries for a bright, refreshing contrast to the rich mint frosting.
• For a St Patrick’s day dessert spread, arrange them on a tiered tray with shamrock-shaped cookies and green candies—it looks festive and fun!
• They’re perfect as chocolate birthday cupcakes too—top each with a candle and watch the smiles light up.
• Enjoy them slightly chilled on a warm day; the frosting gets extra firm and the mint flavor really pops.

Storage and Reheating Instructions

• Room temperature: Store in an airtight container for up to 2 days. Frosted or unfrosted works.
• Refrigerator: Keep in an airtight container for up to 5 days. Bring to room temperature before serving for the best texture.
• Freezer: Cupcakes freeze well unfrosted for up to 3 months. Thaw overnight in the fridge, then frost before serving.
• Reheating: Warm slightly in the microwave for 5–10 seconds to soften the cupcake without melting the frosting.
