Key Lime Curd Mousse is super easy to make!
Key Lime Curd Mousse is creamy with a sweet and tangy flavor. I used leftover key lime curd, but you can easily make your own in the microwave.
For Spring Sweets Week, I made some Key Lime Curd Coconut Thumbprint cookies. They were so delicious! I rolled half in coconut and half not because the hubs doesnโt really like coconut. For me, I think itโs a texture thing for him. Heโs tried coconut chips and liked those. So, if you think you donโt like coconut, then try coconut chips. If you still donโt like coconut, then itโs a flavor thing and not a texture thing.
I had leftover curd from those cookies. So, I froze it. Yes, you can freeze curd for up to 1 year if stored properly. Luckily, I have a vacuum sealer which means I have less waste from freezer burn. If you donโt have a vacuum sealer, I highly recommend them. We got one when we go the chest freezer. Granted, we havenโt used the chest freezer too much lately. But I do keep some things in there like the bowl to the ice cream maker, a whole duck for the holidays, the second corned beef I bought because I love corned beef.
We used to use both more when we shopped at one of those wholesale stores. But we havenโt really felt a need to shop at one of those stores for a while. The hubs works at Walmart so we get a discount on all the groceries. And we just havenโt bought a lot in bulk lately. And with grocery pick up, thereโs little to no impulse buys of marked down meats. I sort of miss those, though. Maybe Iโll start planning a trip inside to peruse the meat aisle.
Whatโs in key lime curd?
Itโs super simple. Thereโs key lime juice, eggs, sugar, and butter. Thatโs all. And you can swap out whatever citrus you want for the key lime juice. Itโs such a simple a easy recipe. I donโt know why I donโt make curd more often. Maybe it has to do with the citrus thing and the hubs doesnโt like those for dessert. Yes, heโs a bit picky, but calls ME the picky one.
Citrus curd is super simple to make, too. You can make it in the microwave! Yes. I learned this when I was researching easy curd recipes for my lemon daisy tartlets I made several years ago. For me, itโs easier to make this kind of curd than the traditional kind. I tend to curdle the eggs in the traditional method. I only had not even an 1/8 teaspoon of cooked egg when I strained this batch of key lime curd.
How you make key lime curd in the microwave?
Basically, you combine everything in a microwave safe bowl and then microwave it on 1-minute intervals, stirring in between. The good thing about the microwave is the way it heats things up. The magnetron creates microwaves that cause water molecules to vibrate.
This is why things with high water content like vegetables to cook faster. And why this curd cooks as evenly and quickly as it does. Just keep microwaving the curd at 1-minute intervals and stirring until the curd reaches the consistency you want. I like mine a little thicker than most because Iโm using in something and donโt want it to get runny.
What is in key lime curd mousse?
Well, thatโs easy. Itโs the key lime curd, whipping cream, and powdered sugar. Now the amount of powdered sugar will depend on your taste buds and how tangy your curd is. But be careful not to add too much powdered sugar or else the egg whites might not reach stiff peaks. Itโs a delicate balance. For me, I like the sweet tart combination of this key lime curd mousse, so I stuck with 1/4 cup of powdered sugar and 1 cup of whipping cream.
I added a cup of the key lime curd to the whipped cream mixture. And I still had some curd leftover. Since I didnโt have cookies to make the same kind of mousse I did with the mango mousse, I opted for a parfait style key lime curd mousse. I layered the leftover key lime curd in mine and just put a dollop on top for the hubs. Because I didnโt want to waste the leftover key lime curd. It was too delicious to discard!
How do you make key lime curd mouse?
Well, I already talked about how to make the curd. If donโt have leftover curd like I did and will be making it for this recipe, then make sure you let it chill for at least 2 hours. It will thicken as it chills, and it will blend in better with the whipped cream if itโs chilled.
Once the curd is chilled then you whip the cream with the powdered sugar. Feel free to add in some vanilla extract if you want. Just make sure it doesnโt have too high an alcohol content and might mess up the whipped cream.
Funny story. Well, not so funny, but a true story. Iโm standing in the kitchen using the whisk attachment on my hand mixer making this key lime curd mousse. Iโve got it on high speed and just whipping away. Next thing I know, the whipped cream is going all over the place. For the life of me I cannot figure out why. I have made a complete mess of the whipped cream for no reason I can think of.
I check that Iโve put the beater in the correct hole. Is it secure and in the right spot? Is the beater where it belongs? I trouble shoot everything I can think of. And then I see it. One of the tines of the beater broke and itโs free on one side.
The mixer isnโt that old, and I havenโt used the whisk that often. I get pissed and grab the pliers to break the loose piece off. And it happened again today as I whipped egg whites for a recipe later this week! So now, my whisk attachment has 2 tines on it.
What does key lime curd mousse taste like?
Sweet tart creamy goodness!! The sweetened cream and the sweet tart curd make for a delicious citrus key lime curd mousse. And the whipped cream and creamy curd means itโs double creamy and delicious. It tastes rich without requiring a ton of effort.
I love the sweet tart flavor of this mousse. And I love the layers of leftover curd in between the mousse. I wish I had cookies to really make it a decadent dessert with a layer of maybe chocolate or caramel cookies. That would be totally delicious. I might have to try that next time I make this. Because there will be a next time.

I love fruit curd (especially lime) and this is a great way to turn it into a proper dessert dessert without a lot of extra work. Genius!
Thank you! I have made more microwave curd now that I know I can. So much easier than stove curd.
This looks gorgeous and is a perfect dessert to serve for special occasions. I love how you froze the lemon curd and used it.
It freezes well! I was on the fence, but it came out perfectly fine.
Love that this is done in the microwave! We never have leftovers to freeze because my guys will just eat it by the spoonful.
My hubs doesn’t do citrus desserts so I knew I’d have leftovers. LOL
These are beautifully appealing. I always love a citrus dessert. As for markdowns, check to see if flashfood is in your area yet. They have deals on meats. I’d been getting steaks and lamb on deep discount.
I’ve seen them, but I’m not sure they’re in my area yet. I’ll keep an eye on them though.
I love key lime and this is the perfect refreshing dessert for brunch!
Thank you!
These are gorgeous and look soooo refreshing!! Perfect for any citrus!
Thank you so much!
Oh yum! Love the layering. It sound amazing with the sweet and tangy flavors.
The sweet cream and tangy filling was a fun twist to this mousse.
