Essential Ingredients
The charm of Grape Soda Cupcakes lies in their vibrant, soda-inspired ingredients. Here’s what you’ll need and why each one matters:
For the Cupcake Batter
- Egg Whites (4, room temperature): Provide structure and a light, airy texture without the yolk’s richness.
- Vegetable Oil (½ cup): Adds moisture for a tender crumb.
- Grape Soda (1½ cups): Infuses the batter with fizzy, grape flavor and helps with leavening.
- White Cake Mix (15.25 oz): Serves as a neutral base to highlight the grape flavor.
- Unsweetened Grape-Flavored Drink Mix (0.14 oz, one packet): Boosts the grape flavor with a concentrated punch.
- Purple Gel Food Coloring (4–6 drops): Enhances the visual appeal with a vibrant purple hue.
For the Buttercream Frosting
- Salted Butter (1 cup, 2 sticks, softened): Forms a creamy, rich base for the frosting.
- Pure Vanilla Extract (2 tsp): Adds a warm, sweet note to balance the grape flavor.
- Pure Almond Extract (¼ tsp): Enhances the frosting with a subtle, nutty depth.
- Powdered Sugar (4 cups, sifted): Sweetens and thickens the frosting for piping.
- Heavy Cream (2–3 tbsp): Adjusts the frosting to a smooth, pipeable consistency.
- Purple Gel Food Coloring (4–6 drops): Creates a uniform, vibrant purple frosting.
For Garnish (Optional)
- Purple Sparkling Sugar: Adds a crunchy, glittery finish for a festive look.
Substitutions and Variations
- Egg Whites: Replace with ½ cup aquafaba (chickpea liquid) for a vegan version, whipped to soft peaks.
- Vegetable Oil: Swap with canola oil or melted coconut oil for similar moisture.
- Grape Soda: Use another fruit-flavored soda (like orange or cherry) and a matching drink mix for a different flavor.
- Cake Mix: Use a gluten-free white cake mix for dietary needs or a vanilla cake mix for a slightly richer base.
- Drink Mix: Substitute with another unsweetened drink mix flavor (like cherry or blue raspberry) and adjust food coloring.
- Butter: Use vegan butter for a dairy-free frosting.
- Heavy Cream: Replace with non-dairy milk (almond, oat, or soy) or coconut cream for a dairy-free option.
- Garnish: Swap sparkling sugar with sprinkles, crushed grape-flavored candies, or edible glitter.

Step-by-Step Instructions
Making Grape Soda Cupcakes is fun and straightforward with a few simple steps. Follow these instructions for perfect cupcakes every time:
- Preheat and Prep:
- Preheat the oven to 350°F (175°C).
- Line a standard 12-cup muffin tin (and a second tin for extra batter) with cupcake liners.
- Tip: Use colorful or themed liners to match the vibrant purple cupcakes for a festive presentation.
- Mix the Cupcake Batter:
- In a medium mixing bowl (2–3 quarts), combine 4 egg whites (room temperature), ½ cup vegetable oil, and 1½ cups grape soda.
- Use a handheld mixer on medium-low speed to mix until well combined, about 30–45 seconds.
- Lower the mixer speed to low and add the 15.25 oz white cake mix and 0.14 oz unsweetened grape-flavored drink mix. Mix just until incorporated and the batter is a uniform light purple, about 20–30 seconds.
- For a deeper purple, add 2–3 drops of purple gel food coloring and mix until no streaks remain and the color is uniform.
- Tip: Avoid overmixing to keep the cupcakes light and fluffy, and use room-temperature egg whites for better emulsification.
- Fill and Bake:
- Fill each cupcake liner ⅔ full (about 2–3 tbsp of batter) to allow room for rising.
- Bake for 15 minutes, or until a toothpick inserted into the center comes out with only a few crumbs (not wet batter). Start checking at 12 minutes, as ovens vary.
- Carefully remove the cupcakes from the muffin tin and transfer to a wire cooling rack to cool completely, about 20–30 minutes.
- Tip: Use a cookie scoop for even portions, and don’t overfill liners to prevent overflow.
- Make the Buttercream Frosting:
- Using a stand mixer or a large mixing bowl (4–5 quarts) with a handheld mixer on medium-high speed, beat 1 cup softened salted butter, 2 tsp pure vanilla extract, and ¼ tsp pure almond extract for 1–1½ minutes, until light and fluffy.
- Lower the mixer speed to low and add 4 cups sifted powdered sugar, 1 cup at a time, alternating with 2–3 tbsp heavy cream, until fully incorporated and smooth.
- Increase the mixer speed to medium-high and beat for 30–45 seconds until the frosting is creamy and pipeable.
- Lower the speed to medium, add 4–6 drops of purple gel food coloring, and mix until the color is uniform with no visible streaks.
- Tip: Sift the powdered sugar to avoid lumps, and adjust cream for a thick but pipeable consistency.
- Frost the Cupcakes:
- Fill a disposable piping bag fitted with a shaped tip (like a star or round tip) or a gallon-size Ziploc bag with a corner snipped off with the buttercream frosting.
- Hold the tip about ½ inch above the surface of a cooled cupcake and use steady, even pressure to pipe the frosting in a spiral pattern, starting from the center and working outward.
- Repeat for all cupcakes.
- Tip: Chill the frosting for 10 minutes if it’s too soft to hold shape, and practice piping on a plate for consistent spirals.
- Garnish and Serve:
- Sprinkle the frosted cupcakes with purple sparkling sugar for a glittery, festive touch.
- Serve at room temperature, perfect for parties, picnics, or dessert tables.
- Tip: Add garnishes immediately after frosting to ensure they stick, and store ungarnished cupcakes if not serving right away.

Assembly
Assembling Grape Soda Cupcakes is all about creating a vibrant, soda-inspired treat with a polished finish. Here’s how to make them look and taste incredible:
- Bake Thoughtfully: Fill liners evenly for uniform cupcakes, bake just until done for a fluffy texture, and pipe the frosting in neat spirals for a professional look.
- Presentation Tips:
- Display cupcakes on a tiered stand or colorful platter to highlight their bright purple frosting and sparkling sugar.
- Garnish with extra sparkling sugar, grape-flavored candies, or small soda-themed decorations for a playful vibe.
- Serve in fun, patterned liners or on dessert plates with a fork for a whimsical presentation, perfect for kids’ parties or summer events.
- Pair with a glass of grape soda, sparkling water, or milk for a complete soda-shop experience.
Storage and Make-Ahead Tips
Grape Soda Cupcakes are best fresh but can be prepped or stored with these tips to keep them delicious:
- Make-Ahead:
- Bake the cupcakes up to 1 day in advance, cool completely, and store in an airtight container at room temperature. Frost and garnish just before serving.
- Prepare the frosting up to 2 days ahead, store in an airtight container in the fridge, and re-whip briefly before piping.
- Tip: Don’t frost too far in advance, as the frosting may soften the cupcake tops over time.
- Storage:
- Store unfrosted cupcakes in an airtight container at room temperature for up to 2 days or in the fridge for up to 5 days.
- Store frosted cupcakes in the fridge, covered, for up to 5 days, as the frosting contains dairy. Let sit at room temperature for 15–20 minutes before serving for the best texture.
- Tip: Use a cupcake carrier or cover loosely with plastic wrap to protect the frosting spirals.
- Freezing:
- Freeze unfrosted cupcakes in an airtight container or freezer bag for up to 2 months. Thaw at room temperature for 1–2 hours, then frost and garnish.
- Freeze frosting separately in a freezer-safe container for up to 2 months, thaw in the fridge overnight, and re-whip before using.
- Tip: Avoid freezing frosted cupcakes, as the frosting may become grainy or weepy when thawed.
Recipe Variations
Grape Soda Cupcakes are versatile and fun to customize. Here are some creative twists to try:
- Cherry Soda Cupcakes: Use cherry soda and cherry-flavored drink mix with red gel food coloring for a cherry soda-inspired treat.
- Orange Soda Cupcakes: Replace grape soda with orange soda, use orange drink mix, and tint the batter and frosting orange.
- Blue Raspberry Soda Cupcakes: Swap for blue raspberry soda and drink mix with blue gel food coloring for a vibrant blue cupcake.
- Lemon-Lime Soda Cupcakes: Use lemon-lime soda (like Sprite) and a citrus drink mix, tinting with yellow or green food coloring.
- Gluten-Free Soda Cupcakes: Use a gluten-free white cake mix and ensure the drink mix and garnishes are gluten-free.
- Vegan Soda Cupcakes: Replace egg whites with aquafaba, use vegan butter, non-dairy cream, and a vegan cake mix.

FAQs
1. Can I use a different cake mix flavor?
Yes! A vanilla or yellow cake mix works, but white cake mix keeps the grape flavor and color vibrant. Adjust food coloring as needed.
2. Are these cupcakes healthy?
They’re an indulgent treat, but you can lighten them by using a reduced-sugar cake mix, less powdered sugar in the frosting, or smaller portions. Enjoy in moderation.
3. Can I make these vegan?
Yes! Use aquafaba (whipped chickpea liquid) for egg whites, vegan butter, non-dairy cream, and a vegan cake mix. Ensure the drink mix and garnishes are vegan.
4. Why are my cupcakes dense?
Overmixing or using cold egg whites can cause density. Mix just until combined, and use room-temperature egg whites for a light texture.
5. Can I skip the food coloring?
Yes! The grape drink mix adds a light purple hue, but food coloring deepens it. Omit for a subtler color or adjust to taste.
6. How do I pipe perfect frosting spirals?
Use a piping bag with a shaped tip, chill the frosting if too soft, and practice steady pressure on a plate first for consistent spirals.
7. Can I prep these for a party?
Yes! Bake up to 1 day ahead and store unfrosted at room temperature. Frost and garnish on the day of serving for the freshest look.
8. What’s the best way to store leftovers?
Store unfrosted cupcakes at room temperature for 2 days or in the fridge for 5 days. Store frosted cupcakes in the fridge, covered, for up to 5 days.
