A delicious blueberry buttercream made with fresh blueberries.
I really don’t like to see anything go to waste and I almost always have leftovers after baking something. Extra buttercream, ganache, cupcakes, etc. I store all of this in my freezer, but it can get out of control every once in a while, so I like to find things I can make with the extras.
In this case I used the following leftovers to make the perfect lemon cupcakes with blueberry buttercream.
- (pink) buttercream from the Pretty in Pink Ombre Cake
- meyer lemon cupcakes from the Meyer Lemon Bundt Cake
- (shrivelled) blueberries from the Blueberry Tart
The process was pretty simple AND successful considering I winged the entire thing.
While the buttercream and cupcakes were defrosting, I cooked down the blueberries, pushed them through a strainer, and reduced them to a thick sauce. I then cooled the sauce completely and added about 2-3 Tbsp of it to the room temperature buttercream. I folded it in by hand, but the buttercream was separating a bit so I threw it into the mixer and beat it for a couple minutes and it came out perfect!
It’s important to note that the starting buttercream was PINK. If you want yours to turn out the same color as these ones, make sure you use a base of pink. I’m sure the color would turn out just as pretty with white buttercream though, likley more of a pretty pastel blue.
I love the flecks of blueberries in these.
With the leftovers, I had just enough to ice the 6 cupcakes I had. Perfect. I managed to pick out a handful of un-shriveled blueberries as garnish, but the pickings were slim!
Classic combo of lemon and blueberry was a success. And YAY to no wasted leftovers!

I have a very basic question. When you strain the blueberries, do you use the liquid in the frosting, or do you use the meat of the blueberries that is still in the strainer?
Olivia says
Hi Danielle! You discard what’s in the strainer and use the liquid — it should be quite thick though — like a jelly.
Milena says
I’m so excited to try this! I love your page! Would I be able to follow the same recipe but use strawberries instead of blueberries?
Olivia says
Hi Milena! Yes, it would work fine with strawberries too π
Jen says
I tried making this and followed all the steps to your vanilla buttercream to be disappointed that the blueberry buttercream ended up as simply just as vanilla buttercream with a change of color. I don’t know maybe I did it wrong…but the taste of vanilla buttercream after putting in the blueberry sauce taste exactly the same honestly.
Olivia says
I’m sorry to hear that Jen! It’s definitely not an overpowering blueberry flavour, but it should be there. You can try increasing the amount of blueberry syrup or decreasing the sugar/vanilla to help the blueberry stand out.
Dahiana says
Hi! Same happened to me but I added just a Tiny amount of blueberry extract, to help bring out the flavor. I want to say maybe itβs the blueberries, mine were a little sour but after the extract it was perfect!

Good for you for using all those left over things, I have to confess I’m terrible and throwing stuff out. This blueberry buttercream looks so pretty and I can imagine tastes divine!
Olivia says
It was really good with the lemon cupcakes! I’ve been guilty of chucking stuff out too, it happens sometimes, but I’m happy when I can find a use for everything :).
Chrisy @ Homemade Hooplah says
I already said so on Instagram, but your photos and frosting technique is just beautiful! These wouldn’t look near as good if I made them, but at least they’ll still taste great π Our little garden has blueberries growing – here’s hoping I can pull this recipe off in a few weeks!
Olivia says
Thanks Chrisy! I’m confident yours would look just as amazing! Truthfully I scraped the first pass on the frosting off the cupcakes, so this is take #2 :).
Dani @ House in Tillford says
Im totally the same, hate throwing out remainders. These look delicious, the berry and lemon would taste so good together!
Olivia says
I wish one day to make only enough for one recipe of anything and not to have any leftovers!

Thalia @ butter and brioche says
I’ve never made a blueberry flavored butter-cream before but it sure sounds delicious and the color is just incredible. I can imagine how perfectly it compliments a lemon based cake too!
Olivia says
Thanks Thalia! The color turned out especially pretty I think, thanks to the pink frosting.
