This year my son turned twenty. What!? I feel old and like time is moving way too fast. Ok, back to the point…I’d been working on some cool birthday cupcake toppers for him that I had planned to put on top of chocolate cupcakes (since forever that’s what he’s asked for.) Out of the blue, he texted that all he really wanted for his birthday was some lemon cake.
Actually he said, and I quote here, “Mom, I don’t need any money for my birthday. All I want is a bad to the bone lemon cake.” Seriously, that’s what he said.
So of course I immediately changed gears because well, I’m still in the throws of the empty-nest syndrome (even though technically I’ve got step-kids.) Anyway, my only son says he wants lemon cake for his birthday, then that’s what he’ll get.

I did, however come to a compromise. I mentioned I had been working on some cupcake toppers especially for his birthday and that he’d have to be happy with lemon cupcakes instead of a large cake. He certainly didn’t seem to mind.
I had only a few days to write up and test the recipe before his birthday was here and so I decided to use my Favorite Vanilla Bean Cake recipe as a base and change it up to give it a blast of lemon flavor.
Remember, he said he wanted a ‘bad to the bone’ lemon cake, so I tried to pack as much lemon flavor into those cupcakes as I could.
Let me tell you I was actually surprised at how much I liked them. I’ve never been much of a lemon cake fan, but I ended up eating four when I was finished. FOUR! Not even kidding.
These cupcakes aren’t complicated to make. When you make the favorite vanilla bean cake, you use the reverse creaming method, which is when you’ll mix the butter with the flour first to coat it.
For these cupcakes though, you’ll use the regular creaming method, which just means you’ll mix the sugar into the butter first. You’re probably used to seeing more recipes that use the regular creaming method.
For this recipe, you’ll need real lemons and you’ll need to zest the lemons. Make sure to not grate them too far down (like into the white of the lemon), or it’ll be bitter.
You’ll also add in a package of lemon pudding. Yep, I told you I was really going crazy with the lemon flavor. Make sure to reserve one tablespoon of the dry pudding mixture, because you’ll want to add that to your buttercream.
These lemon sour cream cupcakes have a soft consistency that’s moist, with just the right amount of lemon taste, then topped with buttercream that’s packed full of lemon flavor.
TIPS & FAQS FOR MAKING THE LEMON CUPCAKES:
- Use cake flour if you can get it…you’ll get a softer cake. If not, you can make a substitute: For every cup of cake flour called for in the recipe, use one cup of all purpose flour instead and remove two tablespoons of it, then replace that with two tablespoons of cornstarch.
- Make sure to use real butter…not margarine.
- When zesting your lemons, don’t get too crazy and zest the white part of the lemon…that part is bitter.
Ok, ready for the recipe? Here ya go.

Instructions
For the cupcakes:
- In a mixing bowl, whisk together the cake flour, baking powder, baking soda and salt. Set aside.
- In another bowl, whisk together the sour cream, milk, oil and lemon zest. Set aside.
- In a large mixing bowl, beat the butter until smooth. Add sugar and beat until fluffy.
- Add in eggs one at a time, beating just until combined after each.
- Alternately add in the flour and liquid mixtures. (Add a third of the flour mixture and beat until just combined. Add half the liquid mixture and beat just until combined. Add another third of the flour mixture, mix until combined. Add in the last half of the liquid mixture, mix, then add in the last third of the flour mixture and mix only until combined.) Be very careful not to over mix. Only mixed until well combined.
- Add the package of dry lemon pudding mix (reserving 1 tablespoon for the buttercream) and mix.
- Add in a couple drops of yellow food coloring and mix. Fill cupcake liners slightly over halfway full and bake at 350 degrees for about 20 minutes. Once baked, cool on a wire rack.
For the lemon buttercream:
- Add two cups of butter (4 sticks) to a mixing bowl and beat until smooth.
- Add three cups of confectioners sugar and beat.
- Add in the lemon juice and the last three cups of confectioners sugar and beat again until mixed well.
- Now add in the lemon zest and one tablespoon of the lemon pudding mix and mix well. You can also add in a bit of yellow food coloring.
- If your buttercream is too thin, mix in another cup of confectioners sugar. If it's too thick, just add in a little more lemon juice.

En mi pais no consigo pudin de limón, con que lo puedo sustituir?
Thanks.
Kara Jane
If you don’t have lemon pudding available for the cupcakes, try adding in another teaspoon of lemon zest to the batter. That should give the lemon flavor a little more boost. Hope this helps!
Melissa
Which tip did you use? 1M?
Kara Jane
Hi Melissa, I think that one was a 2D tip, but it’s quite possible it was a 1M. I use those two constantly 😉
Bobbi
For the lemon pudding is it instant pudding or the cooked type pudding? Thanks!
Kara Jane
Hi there, You’ll want to use the instant pudding. 🙂
Kelly
Can you use this recipe to make a cake?
Kara Jane
Hi, I haven’t made it into cake, only cupcakes so far, but there isn’t any reason why it wouldn’t work as a cake. Just bake it at 350 degrees and start checking it at about 30 minutes or so. The outside should lightly brown, the top will bounce back when lightly touched and a toothpick inserted will come out with just a few crumbs on it. The batter should be enough to fill 2, 8″ round pans or 3, 6″ round pans.
Kelly
Great Thanks!
MARIANNE KOWAL
I really enjoyed making these today, they are super moist and bursting with flavour.I actually used plain greek yogurt instead of sour cream. I wonder if this recipe could be made in a vanilla version, omit the lemon zest, add vanilla extract and use vanilla instant pudding, that will be my next baking adventure. Thanks for sharing!
Kara Jane
Hi Marianne, I’m so glad you liked the cupcakes! Yay! I actually do have a recipe that is very similar to this one, but it’s vanilla. It doesn’t include pudding, but it doesn’t need it either. It’s moist and has a really nice texture. You can find it here: https://iscreamforbuttercream.com/favorite-vanilla-bean-cake/
Tangela Jenkins
Hi,
These look incredibly delicious! Can lemon extract be added to boost the lemon flavor? If so, how much do you recommend?
Kara Jane
Yes you can add lemon extract. I’d probably add about a teaspoon and that should really boost the flavor.
Pamela Mosher
Hi, Can sugar free lemon pudding be used? Is the pudding more for flavor or texture?
Thank you
Kara Jane
Hey Pamela, yes I think that would be just fine.
Natalie
Hello Kara, I am looking for a lemon cake that would be good for stacking. would you recommend this recipe for a 3 tier cake or would you just change the flavor in your vanilla bean cake recipe? Which is one of my favorites! Thanks for your time!
Take care
Kara
Hi Natalie, this recipe is very similar to the vanilla bean cake. I would go with this one. it should be just fine as a layer cake and for stacking, as long as you use proper doweling. If you like the mixing method of the vanilla cake (the reverse creaming method), you could do that with this recipe as well. The reason I used the regular creaming method for the cupcakes is to get them to puff up and have rounded tops, but you don’t necessarily need that for layer cakes. it’s up to you though…either way should work.
Rhonda McNeal
These cupcakes were a hit with everyone. Delicious.
Kara
Hey Rhonda…yay!!! I’m so glad you liked them! 🙂
meena gupta
hi kara the recipe is amazing. can i have the replacement of egg.want to try it eggless.
Kara
Thanks 🙂 Eggs are a little tricky to sub out. That might be something you’d need to experiment with because really no substitution is going to make it come out exactly. I have a post on baking substitutions if you want to check that out. There’s a section in that post about eggs. https://iscreamforbuttercream.com/cake-baking-substitutions/
Robin
You had sent a bottle of lemon curd in one of your quarterly boxes when you used to do them. Could this be used to fill these cupcakes?
Thank you,
Kara
oh yes…that would be really good!
Robin
Thank you. 😊
