Lemon Blueberry Crazy Cake (a.k.a. Wacky Cake), is a vintage Depression Era cake that has no eggs, no milk and no butter! One of the EASIEST, budget-friendly cakes you can make. Full of tangy lemon flavor, bursting with juicy blueberries, you won’t believe how moist and delicious this cake is!
LEMON BLUEBERRY CRAZY CAKE – A DEPRESSION ERA RECIPE
This moist and delicious lemon blueberry cake is made in ONE BOWL without eggs, milk or butter – you don’t even need a mixer! I adapted this wonderful cake from the cherished Chocolate Crazy Cake. The original vintage chocolate cake was created during the Great Depression, when eggs, milk and butter were hard to come by. Because this cake is egg and dairy-free, it’s a great recipe to have on hand for people with egg and dairy allergies or vegans. But you don’t have to have allergies or be vegan to fall in love with this fantastic, allergy and budget-friendly cake!

FREQUENTLY ASKED QUESTIONS FOR LEMON BLUEBERRY CRAZY CAKE:
Yes! Make sure they are thawed before adding to the batter.
Because there are no eggs, you want the baking soda and vinegar to combine and react/interact last, right before baking, this is what makes the cake rise. Some people think you don’t need to do this, I always have whenever I make a Crazy Cake. It’s a quick step, and all the crazy cakes I have created over the years have ALWAYS turned out perfect.
Yes, vinegar is a must in a crazy cake recipe, because it’s an important part of the leavening process. The vinegar reacts with the baking soda, which is what makes the cake rise. You don’t taste a hint of the vinegar in the finished cake.
You can use apple cider vinegar and also white vinegar.
For Lemon Blueberry Crazy Cake, you can use canola oil, vegetable oil and olive oil.
Yes! Simply use a 9×13 baking pan.
The cake get its moistness from the oil, and becomes fluffy from the chemical reaction between the vinegar and baking soda.

Nancy Young
I’ve made many of your crazy cakes. All are very good but Lemon Blueberry is my favourite…can I make this as a loaf (9”x5”) and if so, what temperature and how long? 😋
Mary Neumann
Hello Nancy, Lemon Blueberry is one of top favorites, too! I have never made this in a loaf pan. If you try, I would bake it at the same temp and begin checking the center of the loaf with a toothpick around around 50 to 55 minutes. It may take up to an hour or more to bake through due to the depth of the pan. If you do make it into a loaf, please stop by and let me know how it turned out and how long it took to bake. Happy baking!
MaryLou Vocke
First Crazy Cake I ever made and it was DELICIOUS!!!! Will try
other flavors, but need to know if and how you can freeze it.
Mary Neumann
Yes you can, Marylou, but it’s best to freeze it without frosting.

Shirley
I made the vanilla cake— yes, should have checked centre— will do next time for sure. Is it possible to use less sugar?—seems so high for the amount of flour. Always looking to use less sugar.
Nancy
I have made this several times as cake and it’s delicious. Could I make it as a loaf, 9 x 5 tin? Would I need to adjust baking time?
Beth
I made gluten free cupcakes for a baby shower and these were super delicious. I used gluten free flour, olive oil, and fresh lemon juice for the cupcakes and powdered sugar and fresh lemon juice for a drizzle on top. I put them in pretty baking wrappers and kept them in the refrigerator for a day. So moist and yummy.
Heather
Can I use lemon juice instead of lemon extract?
Thanks!
Mary Neumann
When I created my Lemon Crazy Cake version (just lemon) over 11 years ago, I tried using just lemon juice and zest, I could not get the taste, texture and rise I was looking for. Next, I used lemon extract and got what I was hoping for. You could give it a go and see if you like the texture and flavor, Heather.
Lori L
I made this for a luncheon and doubled the recipe for a 13 x 9. It worked very well, watched every 5 minutes at end till center was done. I don’t like lemon and I found it delicious! The zest and blueberries were great. They asked for more but it was gone!
Renee
Thank you so much for sharing this. My daughter-in-law who is nursing her baby has eliminated all dairy because of his eczema and thought she wouldn’t have a birthday cake this year! But I’m going to make this for her and I’m so excited. I wondered if you have ever tried making it in layers? I’m guessing it’s probably too moist to hold up like that? But I found a wonderful vegan buttercream recipe that I wanted to try because I like to decorate my cakes. Thank you again so much for sharing these! I’ve made wacky cocoa cakes for years, but didn’t know you could do all these other varieties.
Mary Neumann
Hello Renee,
I am SO HAPPY you found my Crazy Cake recipes. I have not made a layer cake with this one I created, but I have done a layer cake many times with the original chocolate recipe from the Depression era – you can see that here: https://sweetlittlebluebird.com/two-layer-crazy-cake-no-eggs-milk-or-butter/
I think the cake may hold up in layers using a solid/thick frosting, just be sure to place it in the fridge. 🙂
Just in case you didn’t see my page with all my Crazy Cake flavors to date, be sure to check them out here. I update this page as I add new flavors.

Happy birthday to your daughter-in-law and happy baking!
Donna
Moist, lemony, delicious….and almost gone!:(
Melinda L Ruwe
Just made this and the center pieces did not cook all the way. Was worried about overlooking the outside edges. Any suggestions? Also can this be made into muffins?
Mary Neumann
Hello, Melinda,
Be sure to bake the cake on the middle rack of the oven for even baking and check the center to make sure it comes out clean. If you already took the cake out of the oven, there is not much you can do. Next time, if the center is not ready and your oven is running hot (browing the edges too quickly), loosely cover the cake with foil, you can reduce the heat to 325 degrees F and bake an additional 10 mins or so until the toothpick comes out clean.
Yes, the batter can be made into cupcakes/muffins. Bake at the same temp, but you will need to adjust the baking time to the size of the muffins – around 20 minutes, just keep an eye on them, and check the center with a toothpick.
Hope that helps. This is one of my favorite cakes, hope you love it too!
Gabbie
Can you double ingredients and make a larger cake in a Pyrex?
Mary Neumann
Yes – double the recipe and use a 9X13 inch baking pan, Gabbie.
Chris Cole
Can you use applesauce instead of oil?
Mary Neumann
I have not tried applesauce, Chris – might be worth a try.
Kim
I always substitute applesauce for the oil in cakes. You will never notice the difference. It’s still really moist.
Judi
Do you have any nutrition breakdowns on this wonderful cake? Looking for sodium and carb. Thank you.

Diane LaBarge
why can’t I just mix everything up instead of making 3 wells?
Mary Neumann
Because there are no eggs, you want the baking soda and vinegar to combine and react/interact last, right before baking, this is what makes the cake rise. Some people think you don’t need to do this, I always have whenever I make a Crazy Cake. It’s a quick step, and all the crazy cakes I have created over the years have ALWAYS turned out perfect.
Cheryl HEAFNER
Sounds great! I cannot wait to make it.
Beth
I’ve made the carrot cake twice for a crowd, as I was asked to repeat! I dont recall it asking for the wells and Im a little confused by the 3.
I was thinking to use actual lemon juice but I saw your comments on the flavor difference with the extract. It’s quite amazing what can be done with minimal ingredients and made allergy friendly. Thank you for all of your ideas
