Lemon’s Galore!

I’m making Easy Lemon Cake because it’s lemon and citrus season in the Bay Area. My wonderful friends and neighbors have dropped off bags of lemon and oranges at my house over the past week. 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.

One of my friends has a very productive lemon tree with large fruit, a thick rind, and very little lemon juice. It’s perfect for making candied lemon peels for my mom. Another one of my friends has a meyer lemon tree and those lemons are perfect for baking. 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, one mixes 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.

Wacky and Allergy Friendly 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 amounts 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 line with parchment paper for easy clean up.

A New Start in 2017 and Cooking with Rodelle

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.

  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).
