A Decade of Deliciousness: Celebrating My Blog’s 10th Anniversary
Can you believe it? It’s been a full decade since I first embarked on this culinary adventure. To be precise, 10 years and a few days have passed, marking a significant milestone that feels both surreal and deeply gratifying. What started as a small, personal endeavor has blossomed into a thriving community and a true passion project.
Over these past ten years, life has unfolded in countless unexpected ways. I’ve welcomed three beautiful children into the world, navigated five different home relocations, and weathered countless personal ups and downs. Through every season of life, this blog has remained a constant, a creative outlet, and a source of immense joy. It’s grown far beyond a mere “job”; it has become an intrinsic part of who I am. I’ve often said, and truly believe, that even if I weren’t doing this for a living, I would still be blogging. My love for creating and sharing recipes is that profound, and I feel incredibly fortunate to be among those who genuinely love what they do for a living.
The numbers tell a story of their own: over 2,400 posts published. That’s a staggering amount of cooking, tasting, and, most importantly, sharing. The sheer volume of groceries that have passed through my kitchen for these creations is almost incomprehensible! The blogging landscape itself has transformed dramatically over the last ten years, evolving in ways I could never have imagined when I first started. Yet, through all the changes and trends, the journey has been nothing short of exhilarating. I am excited to see what the next decade holds for this space and for all of us who share this love for food.
But none of this would be possible without you, my incredible readers. It’s a genuine honor to know that I might play a small part in what you prepare for your family dinners or what you bring to special celebrations. Being able to share my culinary passion and connect with so many of you is truly the best part of this “job.” My heart swells when I hear about your successes in the kitchen, your favorite recipes, and the joy they bring. So, from the bottom of my heart, whether you’re a regular commenter or a quiet observer, thank you for being here and being a part of this amazing journey.
The Inspiration Behind the Lemon Sunshine Cupcakes
A celebration as significant as a 10-year blog anniversary simply demands cake, doesn’t it? I began pondering what special recipe I wanted to share with you all many months ago, knowing that a decade is quite a momentous occasion. As I reflected, a question I frequently receive surfaced in my mind: “What was the very first thing you ever baked by yourself?” My memory can be notoriously fickle, but one particular baking memory shines brightly through the years.
I distinctly recall making a “Sunshine Cake” when I was younger. My vivid recollection places this event at our local county fair, though my mom suggests it might have been a church carnival or a similar community event. Regardless of the exact venue, the memory of that cake, and the blue ribbon it earned me, is etched in my mind. I can’t recall my precise age or whether the cake was truly exceptional, but I like to believe that moment was the spark that ignited my enduring love affair with the kitchen and the art of baking.

From Layer Cake Aspirations to Cupcake Perfection
For those unfamiliar, a traditional Sunshine Cake is a truly delightful creation: a tender white cake generously filled with bright lemon curd, then elegantly topped with a light, airy marshmallow-style frosting, and finally, sprinkled with toasted coconut. To honor my blog’s milestone, I was determined to recreate this nostalgic dessert. My initial attempt involved baking the cake from scratch and preparing my favorite homemade lemon curd. However, I knew from the start that my curd hadn’t chilled long enough; it was still quite loose, and while a few more hours in the fridge would have certainly helped, I pressed on with an optimistic (perhaps naive) spirit.
As anticipated, the layer cake didn’t hold up. The soft, delicate layers, combined with the unset curd, wobbled and slipped, eventually turning into a delicious but visually chaotic mess. While the flavors were undeniably superb, I knew it wasn’t suitable for sharing as a celebratory post. This baking “mishap” prompted a creative pivot.
To simplify things and ensure a stable, shareable dessert, I decided to transform the concept into individual Lemon Sunshine Cupcakes. After all, my love for cupcakes is well-documented! This adaptation proved to be a true stroke of genius, resulting in an absolute hit. I infused the cupcake batter with a subtle hint of coconut flavor, adding another layer of complexity to the overall taste profile. For the lemon curd, I decided to return to the original Sunshine Cake recipe’s curd, finding its consistency and tang perfectly suited for filling the individual cupcakes. Finally, these sunny treats were crowned with my beloved fluffy frosting—also known as 7-minute frosting or marshmallow frosting—which I’ve perfected over the years. A generous sprinkle of sweetened flaked coconut completed the look and taste, delivering that quintessential Sunshine Cake experience in a perfectly portioned form. I must admit, I lost count of how many of these irresistible Lemon Sunshine Cupcakes I ended up enjoying!
Happy 10th Birthday, Taste and Tell! Here’s to many, many more delicious and inspiring years to come, filled with new recipes, shared memories, and countless culinary adventures!

Mastering Your Lemon Sunshine Cupcakes: Tips for Success
Creating these delightful Lemon Sunshine Cupcakes is a rewarding experience, and with a few key tips, you can ensure they turn out perfectly every time. First, always ensure your butter and eggs are at room temperature for the cupcake batter. This allows for better emulsification, resulting in a lighter, more tender crumb. When mixing the dry and wet ingredients for the cupcakes, be careful not to overmix; stop as soon as the flour streaks disappear to prevent tough cupcakes.
For the lemon curd filling, patience is key. While the recipe is straightforward, allowing the curd to chill thoroughly in the refrigerator is crucial for it to set properly. A well-chilled curd will be firm enough to hold its shape when piped into the cupcake centers, preventing any messy collapses. You can even prepare the lemon curd a day in advance to save time and guarantee optimal consistency. Remember to whisk constantly while cooking the curd to avoid scorching the bottom and ensure a smooth, lump-free texture.
The fluffy marshmallow frosting might seem intimidating, but it’s surprisingly simple to master. Ensure your egg whites are at room temperature and that your mixing bowl is immaculately clean and grease-free for the best peaks. When pouring the hot sugar syrup into the beaten egg whites, do so slowly and steadily while the mixer is running. This allows the egg whites to temper gently and prevents them from scrambling. Beat the frosting for the full 5-7 minutes as instructed; this aeration is what gives it its characteristic dreamy, ethereal texture and glossy finish. Don’t be tempted to scrape the sides of the bowl once the hot syrup has been added, as sugar crystals can form and make the frosting grainy.
When assembling, use a sharp paring knife or a cupcake corer to create a neat cavity in the center of each cooled cupcake. Don’t discard the removed cupcake “plug”; you’ll use a small piece of it to cap the lemon curd filling, ensuring a clean surface for your frosting. Pipe the glorious fluffy frosting generously onto each cupcake, then finish with a sprinkle of sweetened flaked coconut for that signature Sunshine Cupcake appeal.
Storage Suggestions
These Lemon Sunshine Cupcakes are best enjoyed fresh on the day they are made. However, if you have leftovers, they can be stored in an airtight container at room temperature for up to 2-3 days. If your kitchen is particularly warm, or for longer storage, you can refrigerate them. Just be aware that refrigeration can sometimes alter the texture of the frosting slightly. For optimal freshness, bring them back to room temperature for about 15-20 minutes before serving. Enjoy!

- 3/4 cup granulated sugar
- 2 tablespoons cornstarch
- dash of salt
- 3/4 cup water
- 2 slightly beaten egg yolks*
- 3 tablespoons lemon juice
- 1 tablespoon butter
- 1 teaspoon lemon zest
Fluffy Frosting:
- 4 egg whites* at room temperature
- 1 cup granulated sugar
- 2/3 cup light corn syrup
- 1 teaspoon vanilla extract
- sweetened flaked coconut
Instructions
- To make the cupcakes: Preheat the oven to 350ºF. Line 36 muffin tins with cupcake liners.
- In a medium bowl, whisk together the flour, baking powder and salt; set aside.3 cups all-purpose flour, 2 teaspoons baking powder, 1 teaspoon salt
- In a large bowl, cream the granulated sugar and softened butter with an electric mixer on medium speed until light and fluffy. Add the eggs, one at a time, beating well after each addition until fully incorporated. Beat in the coconut and vanilla extracts.2 cups granulated sugar, 1 cup butter, 4 eggs, 1 teaspoon coconut extract, 1 teaspoon vanilla extract
- With the mixer on low speed, alternately add the flour mixture and buttermilk to the butter mixture, beginning and ending with flour. Add ⅓ of the flour, then ½ of the buttermilk, then another ⅓ of the flour, the remaining buttermilk, and finally the remaining flour. Beat just until blended after each addition, taking care not to overmix.2 cups buttermilk
- Divide the batter evenly among the prepared muffin cups, filling each about ⅔ full.
- Bake for 15 to 18 minutes, or until a wooden skewer or toothpick inserted into the center of a cupcake comes out clean. Allow to cool in the muffin tins for 5 minutes before transferring them to a wire rack to cool completely.
- To make the lemon curd: In a medium saucepan, combine the granulated sugar, cornstarch, and a dash of salt. Whisk in the water, slightly beaten egg yolks, and lemon juice until smooth. Cook this mixture over medium heat, stirring constantly, until it thickens to a pudding-like consistency. Remove the saucepan from the heat and stir in the butter and fresh lemon zest. Transfer the lemon curd to a bowl, cover it with plastic wrap pressed directly onto the surface to prevent a skin from forming, and refrigerate until thoroughly chilled and firm.3/4 cup granulated sugar, 2 tablespoons cornstarch, dash of salt, 3/4 cup water, 2 slightly beaten egg yolks*, 3 tablespoons lemon juice, 1 tablespoon butter, 1 teaspoon lemon zest
- To make the fluffy frosting: In the bowl of a stand mixer fitted with the whisk attachment, beat the egg whites on high speed until they form stiff, glossy peaks.4 egg whites*
- Meanwhile, in a small saucepan, combine the granulated sugar and light corn syrup. Heat the mixture over medium heat, stirring occasionally, until it comes to a full, rolling boil. Immediately remove from the heat.1 cup granulated sugar, 2/3 cup light corn syrup
- Once the egg whites are stiff, slowly and carefully pour the hot sugar mixture in a thin stream down the side of the mixer bowl into the egg whites while the mixer continues to beat on high speed. Continue to beat the frosting for 5-7 minutes, until it forms a shiny, fluffy marshmallow frosting that holds its shape and the bowl is cool to the touch. Beat in the vanilla extract until combined.1 teaspoon vanilla extract
- To assemble the cupcakes: Using a sharp knife or a cupcake corer, carefully cut a cone shape out of the center of each cooled cupcake. Reserve the cut-out piece. Fill the hollowed center of each cupcake with approximately 1 teaspoon of the chilled lemon curd. Replace a small portion of the reserved cupcake piece on top of the curd to cap it, creating a flat surface for frosting. Repeat with all remaining cupcakes.
- Pipe or spread the dreamy fluffy frosting generously onto each filled cupcake. Finish by sprinkling sweetened flaked coconut over the frosting for that perfect Lemon Sunshine Cupcake touch.sweetened flaked coconut
