Lemon’s Galore!

I’m making Easy Lemon Cake because it’s lemon and citrus season in the Bay Area. My friends and neighbors are sharing fruit from their citrus trees and my meyer lemon tree has fruit also. My neighbor has an orange tree and sometimes the fruit is very sweet and sometimes it’s not, in which case I’ll use them to make my award-winning Orange Chiffon Cake.

I’m making an Easy Lemon Cake recipe that is egg allergy friendly, easy to adapt, delicious baked as cupcakes, and as a base for other recipes. If you love lemon recipes, be sure to look at my recipes for Lemon Vanilla Crinkle Cookies and Blueberry Lemon Muffins.

Easy, Crazy, Wacky Cake Basics

Wacky cake is a simple chocolate cake recipe that was invented during the depression era when butter, eggs, and milk were rationed. The recipe is very simple, mix the dry ingredients in a square baking dish and create separate indentations to act as wells for the wet ingredients: oil, vanilla extract, and vinegar. Add water, mix everything up, and bake! This Easy Lemon Cake recipe is inspired by wacky cake but I like to use milk so that the lemon juice and milk can react, create buttermilk, which in turns makes the cake moist and tender. If you avoid milk, you can use any other milk or water in the recipe.

Allergy Aware Wacky Cake & Adaptations

  • Not everyone in our family likes chocolate but everyone loves lemon.
  • I lightened the texture of the batter with some cornstarch, but if you avoid cornstarch, then omit the cornstarch and use a total of 1 1/2 cups of all purpose flour instead.
  • I’ve reduced the amount of sugar to lighten up the calories.
  • I use non-fat milk in this recipe, but you can use water, soy milk, or any kind of milk as needed for your specific allergies. Dairy milk works the best.
  • You could make this recipe gluten-free by using a one to one gluten free mix that includes xanthum gum (or similar ingredient).
  • You could mix everything in a square nonstick baking pan. If you are using a glass pan, mix the batter in a bowl and line the glass pan with parchment paper for easy clean up.

Healthy 2017 and Rodelle‘s Organic Products

2016 was a tumultuous year for my health and every January is a great reminder to refocus and recommit to healthy choices, whatever they may be. I’m eager for a fresh start: exercise more, eat more fruits and veggies, cook more, lose weight, and get more sleep. How about you?

To make the easy lemon cake a little more mom-approved and waistline friendlier, I reduced some of the sugar. I usually serve this cake plain, but if a little sweet topping is a must, be sure to let it cool completely before sprinkling some powdered sugar or drizzling a little lemon icing.

I also love being able to use organic ingredients whenever I can. I used Rodelle Organics Lemon Extract and Rodelle Organics Pure Vanilla Extract for this recipe. The cake tastes wonderful right out of the oven as well as the next day, which is convenient if you are preparing food for a crowd.

This recipe is free of peanuts, tree nuts, egg, soy, fish, shellfish, and sesame as written.

  1. How much is “1 lemon zest”? 1 tsp dried zest? 1 tsp fresh? zest of one whole lemon? Approximately how much zest would that be, 1 tablespoon?

    • Use a regular sized lemon from a supermarket and zest it. If you have a giant one from someone’s backyard, zest half. I don’t measure the amount of zest because I zest directly into the ingredients to get all of the lemon oil that squirts out while zesting. That’s the best. 😉 I hope that helps (great question).

  2. 5 stars
    Delicious! My daughter is allergic to eggs, milk, soy and nuts and has never had “white” cake. We made this together and loved it! Thank you for sharing the recipe!

  3. Do you think I could substitute gluten-free flour (1 to 1) mix for the flour? Food allergies are absolutely no fun, but so thankful I found this site!

    • Hi Amanda, I haven’t actually tried baking it gluten free since there are so many variations of GF flour mixes. I would recommend that you use a commercial GF mix that is ready to use and substitute 1:1 rather than a personal gluten free mix. The GF mixes that you can sub one for one are the easiest to use. I know you can also use a GF wacky cake recipe and modify it to be super lemony. I hope that helps!

  4. I really enjoyed this cake. It was lovely and moist. I made a nice lemon curd and I put a layer of that on my cake and topped it with a dollop of whip cream. This is a keeper in our home. Will be in the menu often.
    Thank You so much for sharing this recipe with us all.
