How to Make:

Quick Overview

This recipe is easy, quick, and satisfying: mix a few ingredients in one bowl, fill liners, bake for about 15–20 minutes, then frost once cooled. The cake is soft and tender, with a touch of mint and a light green hue. Prep time is about 10 minutes, baking time 15–20 minutes, and cooling plus frosting about 20–30 minutes for a total of roughly 45–60 minutes from start to finish.

Ingredients

1 box white cake mix (15.25 oz), ready to use
3 large egg whites, room temperature
1 cup water
1/3 cup vegetable oil
1/4 to 1/2 teaspoon mint or peppermint extract, depending on taste
1/2 teaspoon green food coloring, or more for a deeper shade

Directions

Preheat your oven to 350°F (175°C) and line a cupcake pan with cupcake liners. Use a standard 12-cup pan for the recipe quantity given.
In a large mixing bowl, combine the cake mix, egg whites, water, vegetable oil, mint extract, and green food coloring. Mix until smooth. Use an electric mixer on medium speed for 30–60 seconds, scraping the sides once so everything is fully incorporated. The batter should be lump-free and evenly colored.
Fill each cupcake liner about 2/3 full with batter. Using an ice cream scoop or large spoon helps keep sizes consistent so cupcakes bake evenly.
Bake for 15–20 minutes or until a toothpick inserted in the center comes out clean. Start checking at 15 minutes; bake longer if needed depending on your oven. Rotate the pan halfway through if your oven heats unevenly.
Allow cupcakes to cool completely before frosting. Let them cool in the pan for 5 minutes, then transfer to a wire rack to cool fully; frosting a warm cupcake will melt the topping.
Frost with your favorite buttercream or whipped topping and enjoy! For a mintier frosting, add a drop of peppermint extract and a pinch of green coloring to match the cupcakes.

What to Serve With:

A cold glass of milk or an iced latte to balance the minty sweetness.
Fresh berries or a simple fruit salad for a bright, acidic contrast.
Coffee or hot chocolate for a cozy pairing at a party.
Mini chocolate squares or a drizzle of chocolate ganache for an extra indulgent touch.

Top Tips for Perfecting:

Adjust mint extract carefully: start with 1/4 teaspoon and taste a bit of batter; peppermint can quickly overpower.
Use egg whites instead of whole eggs for a lighter crumb and paler color. If using whole eggs, reduce slightly and expect a slightly denser texture.
Don’t overmix: once the batter is smooth, stop mixing to avoid a tough cupcake.
Even distribution: use an ice cream scoop to portion batter so all cupcakes bake uniformly.
Frosting options: a stabilized whipped topping keeps things lighter, while vanilla buttercream provides richness. Add a tiny pinch of salt to frosting to balance sweetness.
Avoid underbaking: check with a toothpick; wet batter indicates more time needed. Overbaking will dry them out.

Storing and Reheating Tips:

Refrigerator: Store frosted cupcakes in an airtight container in the fridge for up to 4 days. Bring to room temperature before serving for best flavor and texture.
Freezing: Freeze unfrosted cupcakes in a single layer on a baking sheet until firm, then transfer to a freezer bag for up to 2 months. Thaw overnight in the refrigerator and then bring to room temperature before frosting. Frosted cupcakes can be frozen individually on a tray and then wrapped to prevent frosting damage; thaw in the fridge.
Reheating: Warm a cupcake for 10–15 seconds in the microwave on low power if you like them slightly warm, but avoid heating frosted cupcakes directly to prevent melting. For best texture, let frozen cupcakes thaw thoroughly before enjoying.

FAQs

Can I use whole eggs instead of egg whites?
Yes, you can use 3 whole large eggs in place of the 3 large egg whites. The cupcakes may be slightly richer and a touch denser, but they will still be delicious.

How much mint extract should I add for a strong mint flavor?
Start with 1/4 teaspoon in the batter and 1/4 teaspoon in the frosting. Increase up to 1/2 teaspoon total only if you prefer a stronger mint profile—mint extract is potent.

Can I make these cupcakes without green food coloring?
Absolutely. The flavor will be the same; the green coloring is purely decorative. You can use natural coloring alternatives like matcha (use very little) or spinach powder, but these will add subtle flavor changes.

What frosting pairs best with Shamrock Shake Cupcakes?
A classic vanilla buttercream complements the mint flavor nicely. For a lighter option, use stabilized whipped cream or a cream cheese frosting for tang and richness.

Can I turn this into a cake instead of cupcakes?
Yes. Pour the batter into a greased 8- or 9-inch round pan and bake at 350°F (175°C) for approximately 25–35 minutes, checking doneness with a toothpick.
