Ingredients for One Small Ramekin

• 2 tablespoons (30 mL) neutral oil, such as canola or vegetable oil
• 3 tablespoons (39 g) white granulated sugar
• 1 large (32 g) egg white
• ½ teaspoon vanilla extract
• 2 tablespoons (30 mL) milk, I used whole milk here for richness
• 5 tablespoons (40 g) all-purpose flour, roughly ¼ cup plus 1 tablespoon
• ½ teaspoon baking powder
• ⅛ teaspoon kosher salt
• Approximately 1 tablespoon sprinkles, I prefer ‘jimmies’ because they don’t bleed color as much
• Butter for greasing the ramekin
• 2 tablespoons (28 g) unsalted butter, softened to room temperature
• ½ cup (64 g) powdered sugar, add more if you prefer thicker frosting
• 2 teaspoons (10 mL) milk, I again used whole milk
• ½ teaspoon vanilla extract
• A pinch of kosher salt, skip if using salted butter
• Nonpareil sprinkles to top the cake

How to Bake and Frost

1. Preheat oven to 350°F (177°C) and generously butter a 10‑oz (≈4.25″) ramekin; place a small round of parchment in the bottom if desired.
2. In a medium bowl, combine the oil and granulated sugar with a fork until smooth.
3. Whisk in the egg white, milk, and vanilla until the mixture is light and slightly bubbly.
4. Gently fold in the flour, baking powder, and salt until just combined, then carefully fold in the batter sprinkles.
5. Spoon the batter into the prepared ramekin and smooth the top.
6. Bake until golden and a toothpick inserted comes out with just moist crumbs, about 23–27 minutes; the top should spring back when pressed.
7. While the cake cools, mix softened butter and powdered sugar until roughly blended, then stir in milk, vanilla, and salt, adding more milk if needed to reach a spreadable consistency.
8. Remove the cooled cake from the ramekin, trim the domed top with a serrated knife to create a flat surface leaving about ½” space from the ramekin rim, and return the cake to the ramekin.

9. Spread the frosting evenly over the cake top, smoothing it to the ramekin edge.

   

10. Pour nonpareil sprinkles onto a small plate, invert the frosted cake into the sprinkles, and gently press to adhere; lift carefully.

Tips for Perfect Texture

• Don’t Overbake – The secret to a moist single serve dot cake lies in baking just right. Stop when a toothpick comes out clean with just a few moist crumbs. The top should gently bounce back when you touch it.
• Use Softened Butter for Frosting – Soft butter blends smoothly for creamy frosting. If it’s too cold, it lumps and won’t mix well. See how silky buttercream should look in our White Chocolate Raspberry Dream Cake.
• Use the ‘Spoon and Level’ Flour Method – To avoid a dense cake, scoop flour with a spoon into your measuring cup then level it off with a knife instead of dipping straight into the bag. This simple step also keeps bakes like Perfect Blueberry Cheesecake Cookies light and tender.

Flavor Swaps and Add-In Ideas

Want to switch things up a bit? Try these easy ideas that work great for this single serve dot cake:

• Sprinkle Swap: Use jimmies, sanding sugar, or pastel nonpareils depending on your mood—just like you might decorate easy sugar cookies. Jimmies bleed less inside, nonpareils create that classic dot texture on top.
• Oil Options: Canola, vegetable, or avocado oil keeps things moist. You can also swap in melted unsalted butter 1:1 for richer flavor, though it might make the cake a bit denser.
• Milk Choices: Any milk—dairy or plant-based like almond or oat—works perfectly, just swap 1:1. Full-fat milks give the best flavor.
• Egg Swap: Use a whole egg instead of just the white if you like a richer, slightly taller cake. If your batter feels too loose then reduce added liquid by about ½ teaspoon.
• Gluten-Free: Use a 1:1 gluten-free flour blend with xanthan gum for similar texture, but expect a slight difference.
• Chocolate Dot Cake: Add 1 tablespoon unsweetened cocoa powder folded with the flour and a teaspoon more sugar if you want it sweeter. Try chocolate frosting too!
• Zesty or Flavor Boosts: Stir in ½ teaspoon lemon or orange zest, and add a drop of matching extract to your frosting for a fresh pop. Citrus fans might also enjoy our Key Lime Cookies for tart-sweet inspiration.
• Mini Cakes: Double the recipe for two ramekins or pour into a lined muffin tin for multiple mini dot cakes. Watch baking time closely — smaller cakes bake faster.

How to Store and Freeze

Wondering how to keep your single serve dot cake fresh and tasty? Here’s what works best:

• Room Temperature: Keep your frosted cake covered in an airtight container for up to a day. Avoid warm spots so frosting doesn’t melt.
• Refrigeration: Store in the fridge for 4-5 days. The frosting firms up cold, so let the cake sit at room temp for 20-30 minutes before eating for that soft, creamy feel.
• Freezing: Freeze unfrosted cakes wrapped tightly in plastic and in a freezer bag for up to two months. Thaw in the fridge overnight, bring to room temperature, then frost and decorate fresh. Freezing after frosting and sprinkling can dull the topping.
• Reheat: Warm a serving for 8-15 seconds in the microwave (watch closely!) or 5-8 minutes in a 300°F (150°C) oven. If chilled, bring to room temp first or increase oven time slightly.
• Make-Ahead: Bake your cake a day ahead and keep unfrosted in an airtight container in the fridge. Mix up fresh frosting and decorate just before serving for best sprinkle stick and appearance.

Answers to Common Questions

Why only use an egg white?

Using just the egg white makes this single serve dot cake light and fluffy without extra richness. It also keeps the batter small, perfect for one ramekin.

What’s the ‘Spoon and Level’ method?

This method helps you measure flour correctly without packing it down. Fluff the flour, spoon it gently into your cup, then level off the top with a knife. It prevents too much flour, which can make your cake dry.

What’s a dot cake exactly?

Dot Cakes are those mini cakes that became super trendy, covered in frosting and bright nonpareil sprinkles, giving them a fun, playful top texture that’s visually stunning and adds a little crunch. If you love that colorful, crunchy vibe, you might also enjoy Easy Jello Meringue Cookies for a similarly bright, airy bite.

Can I double this recipe?

Yes! You can double it easily to bake two single serve dot cakes in separate ramekins.

Do I have to use nonpareil sprinkles on top?

Not at all. Feel free to use whatever sprinkles you like, or even leave them off for a simpler finish.
