Simple Lemon Curd Frosting Questions Answered
How important is the temperature of the butter?
Using softened butter is crucial for achieving that creamy and fluffy texture in your frosting. It should be at room temperature, about 68-72°F (20-22°C). If it’s too cold, you’ll end up with a lumpy frosting; if it’s too warm, it could become greasy. Allowing the butter to soften for about 30 minutes before starting will make all the difference!
Can I substitute the lemon curd?
Absolutely! While lemon curd gives this frosting its signature zesty flavor, you can substitute it with other fruit curds like lime or orange for a delightful twist. Just keep in mind that different curds may impact the sweetness and tartness, so taste as you go to balance flavors.
How do I store leftover frosting?
If you have any leftover frosting (which might be rare!), store it in an airtight container in the refrigerator for up to one week. Just give it a good stir before using again, as it may firm up a bit. For longer storage, you can freeze it in an airtight container for up to three months. When ready to use, simply thaw it overnight in the fridge and let it come to room temperature.
What if my frosting is too runny?
If your frosting turns out too runny, don’t fret! This can happen if you’ve added too much lemon curd or if your butter was too soft. Simply add more powdered sugar—start with a tablespoon at a time—until you reach your desired consistency. You want a thick yet spreadable texture that holds its shape beautifully on cakes and cupcakes.
Is this frosting suitable for special diets?
This Simple Lemon Curd Frosting contains dairy due to the butter, making it unsuitable for vegan diets. However, you can experiment with vegan butter alternatives and ensure your lemon curd is plant-based if you’re looking for a dairy-free option. Additionally, keep an eye on portion sizes as this recipe yields about 4 servings at approximately 200 calories each.

This delightful frosting comes together quickly! With just 10 minutes of prep time and no cooking involved, you’ll have a luscious topping ready to go. Whether you’re decorating a birthday cake or whipping up some cupcakes, this zesty treat will elevate any dessert in no time!
