Zesty Blueberry Lavender Wacky Cake

by Lauren


We recently decided to join in on the vintage recipe swap that an awesome group of food bloggers (led by CM of Burwell General Store) take part in. This week we revamped the “Busy Day Wacky Cake” from CM’s vintage recipes cookbook. This cake looked quite flavorless to me to be honest. But hey, more room for improvement that way! We had to change or alter at least three significant ingredients and/or techniques to recreate this recipe.

My mother and I did some thorough research on the science of cakes and unique flavor combinations and  decided to make this Busy Day Wacky Cake into a Zesty Blueberry Lavender Wacky Cake!


This makes a fantastic breakfast cake or a great pairing with a cup of afternoon tea. We considered a few optional toppings such as lemon whipped cream or a lemon and lavender glaze, but decided on a light but refreshing dusting of lemon powdered sugar. T’was blissful if you ask me!


Funny story. The original recipe calls for “1 tsp. soda”, not specified as baking soda, it just says soda. Or so I thought. That was dumb because I mixed some seltzer water with vinegar and waited for something cool to happen. Not so much…my mom laughed at me and then we moved on. Needless to say, the recipe definitely meant baking soda. Now, baking soda and vinegar, that creates a super cool fizzy effect like the volcanoes you make for the science fair as a kid. Duh, Lauren.


Now that I’ve told the world about my dumb blonde moment, here is the original recipe:


Here is what we swapped it into (Original ingredient –> New ingredient):

Sugar –> Lavender Sugar

Water/ Vanilla extract –> Vanilla Yogurt

Cocoa Powder –> Lemon Zest

Add Blueberries

Little Yellow Note: While this batter is fantastic to nom on if you  have just had your wisdom teeth pulled, don’t eat the baked version of this cake until your healed!

  1. HI! Love your revamp of the Wacky Cake with the addition of Lavender sugar. So clever. The cake looks and sounds to taste bright and delicious, perfect for spring. Guessing the comment about consumption and wisdom teeth not to be random, I hope you’ll be healed and eating the cake soon! Glad to have you as part of the swap.

  2. Great job with changing the ingredients! Would never have thought of going from chocolate to bluberry and lavender!

  3. i am so excited to see your changes and additions- love the use of lavendar sugar… sounds amazing!

    Haha- the story about the soda made me laugh… The thought crossed my mind for a second as well!

  4. I’m so glad you joined in! This looks heavenly, and I have some lavender I got this weekend needing to be used. Thank you for sharing this recipe, and I hope we see more posts from you!

  5. So creative!! I dont know that I’ve ever had lavender in my food. Maybe in tea. Sounds interesting! Good job!

  6. I’m loving what you did with the wacky cake. Blueberries are pretty popular here in Nova Scotia (seriously, they grow everywhere) and blueberry lemon is one of my favourite combinations. Can you believe that I almost forgot the baking soda in my cake? Kind of defeats the whole purpose… cute story about your soda escapade!

    Good to know i wasn’t the only one. I knew it wouldn’t do anything but for some reason I still tried it. Oops! P.S. Love that you added coffee to yours. Mmmm

  8. Lauren

    No baking soda! That wouldn’t have worked out very well haha. At least you didn’t attempt to use seltzer water!

  9. Lauren
