I love making this 6-Inch Sunshine Citrus Cake when I want something bright, fresh, and perfectly sized for a small gathering or a cozy dessert at home.

Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the Cake

1 cup all-purpose flour

¾ tsp baking powder

¼ tsp baking soda

¼ tsp salt

½ cup granulated sugar

1 large egg

¼ cup vegetable oil

¼ cup freshly squeezed orange juice

2 tbsp freshly squeezed lemon juice

1 tbsp orange zest

1 tbsp lemon zest

¼ cup whole milk or buttermilk

½ tsp vanilla extract

For the Citrus Glaze

¾ cup powdered sugar

2 tbsp freshly squeezed orange juice

1 tsp lemon juice

Zest of ½ an orange (optional)

Directions

Preheat the Oven:
I preheat my oven to 350°F (175°C). I grease and line a 6-inch round cake pan with parchment paper to ensure easy removal.

Mix the Dry Ingredients:
In a medium bowl, I whisk together the flour, baking powder, baking soda, and salt until evenly combined.

Combine the Wet Ingredients:
In another bowl, I whisk the sugar and egg until the mixture looks light and slightly fluffy. I then add the oil, orange juice, lemon juice, orange zest, lemon zest, milk, and vanilla extract. I mix everything well until smooth.

Combine Wet and Dry:
I gradually fold the dry ingredients into the wet mixture, stirring gently until just combined. I make sure not to overmix so the cake stays tender.

Bake:
I pour the batter into the prepared pan and smooth the top. I bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean. I let the cake cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.

Make the Glaze:
In a small bowl, I whisk together the powdered sugar, orange juice, and lemon juice until smooth. If I want extra citrus aroma, I stir in a bit of orange zest.

Decorate:
Once the cake is fully cooled, I drizzle the glaze over the top and let it set before slicing and serving.

Servings and Timing

I find that this 6-inch cake serves about 4 to 6 slices, depending on how generously I cut them.

Preparation time: 15 minutes

Baking time: 25–30 minutes

Cooling and glazing time: about 30–40 minutes

Total time: approximately 1 hour and 15 minutes

Variations

I sometimes add 1 to 2 teaspoons of poppy seeds to the batter for a pleasant crunch and a beautiful look. When I want a stronger citrus flavor, I brush the warm cake with a mixture of orange and lemon juice before adding the glaze.

I also like substituting buttermilk for whole milk to create a slightly richer texture. Occasionally, I swap part of the orange juice with blood orange juice for a deeper color and a slightly different flavor profile.

Storage/Reheating

I store the cake in an airtight container at room temperature for up to 2 days. If I want to keep it longer, I refrigerate it for up to 5 days. Before serving, I let it sit at room temperature so the texture softens.

If I prefer it slightly warm, I heat a slice in the microwave for about 10–15 seconds. I am careful not to overheat it, as that can dry out the cake.

FAQs

Can I make this cake without the glaze?

Yes, I sometimes skip the glaze when I want a less sweet dessert. The cake itself is flavorful and moist enough to stand on its own.

Can I use bottled citrus juice instead of fresh?

I prefer using freshly squeezed juice because I get a brighter, fresher flavor. In a pinch, I can use bottled juice, but I notice the taste is not as vibrant.

What if I only have an 8-inch pan?

If I use an 8-inch pan, the cake will be thinner and bake faster. I start checking for doneness around the 18–22 minute mark to avoid overbaking.

Can I freeze this cake?

Yes, I wrap the fully cooled and unglazed cake tightly in plastic wrap and freeze it for up to 2 months. I thaw it at room temperature and glaze it before serving.

How do I know when the cake is done?

I insert a toothpick into the center of the cake. If it comes out clean or with just a few crumbs, I know the cake is ready.

Conclusion

I truly enjoy making this 6-Inch Sunshine Citrus Cake whenever I crave something fresh, cheerful, and easy to prepare. The lively blend of orange and lemon flavors, paired with the sweet citrus glaze, creates a dessert that feels both comforting and uplifting. For me, it is a simple way to bring a little brightness to the table with minimal effort and maximum flavor.
