The purpose of this Julia Child section of my blog is to document my journey of learning how to cook. To show my successes, my failures, and what I learned along the way.

Since I didn't create these recipes (if only!), I do not post exact amounts of ingredients or word-for-word instructions. If any of these recipes spark your interest, I highly recommend you buy Julia Child's Mastering the Art of French Cooking (affiliate link). It's a great investment and learning tool and contains hundreds of classic recipes.

When in doubt, eat cake.

Before I begin, I just have to say I went out of order on the dessert chapter. What happened- I was at my parent’s house, and I REALLY wanted to cook but I REALLY didn’t want to go to the grocery store.

I was on my last spring break ever so it seemed appropriate to break the rules.

I made the one thing in the book that my mom had all the ingredients already on hand, and that was the butter spongecake.

Fortunately, I have already made two Bavarian creams at this point so I have the whipping pretty much down!

I also have been really excited to make this cake ever since I received the cookbook so it was a good one to skip ahead to. Until this recipe, I had never made a spongecake before and didn’t know where the “sponge” came from.

Now, that I know.. I'll be craving spongecake for the rest of my life. So delicious!

Julia Child Spongecake Recipe: Questions

✽ How do you serve butter spongecake?

As you can see, I went the chocolate route with my spongecake. Which was a delicious choice! I used Julia Child's recipe for Chocolate-butter Icing. I think that this cake can be turned into anything that you want it to be!

You could just sprinkle a bit of powdered sugar on top of the spongecake prior to serving. Julia also suggests serving with fruits and tea.

She also mentions that you can turn it into a strawberry shortcake. Yum!

✽ What is a biscuit spongecake?

Biscuit is pronounced as 'bees-kee' in French.

This spongecake contains both egg yolks and egg whites. Each of them are whisked separately and then folded together with cake flour.

When compared to other types of spongecakes, the biscuit spongecake is drier. However, it can hold its shape better.

This cake can be used in Swiss roll recipes as well as lady finger recipes. To help with the dryness, you can add fruit syrups on top. Source: Amari Bakery.

✽ What makes a sponge cake different than a regular cake?

Traditionally, sponge cakes do not contain butter. The fat comes from the eggs.

The egg whites are whipped and then folded into the batter. The cake does not contain any baking powder or baking soda. The egg whites make the sponge cake rise. So the cake is light and fluffy.

On the other hand, butter cakes (or what I usually think of when I think cake) are made with lots more fat such as butter, shortening, or oil. They use baking powder or baking soda for leavening. With these recipes, you end up with a dense and moist cake. Source: All Recipes.

Fun Spongecake Facts

Find more of these facts on What's Cooking America.

✽ Why are they called sponge cakes?

Simple because of the cake's sponginess! They resemble a sea sponge and were given the name sponge cake.

✽ What is the oldest sponge cake?

The oldest recorded sponge cake dates back to 1615. It was recorded by an Egnlish poet named Gervase Markham. These sponge cakes were probably more similar to what we call cookies- thin and crisp.

Prior to this sponge cake recording, in the late 1400s and early 1500s, Italian cooks started making a new dessert they called 'biscuits' which were similar to what we call sponge cake today.

During the 1700s, yeast started to be replaced with eggs in cakes as the leavening agent.

How to Make Butter Sponge Cake

Julia Child Butter Spongecake Recipe

✽ Step 1: Beat Sugar into Egg Yolks

Let me walk you through the spongecake process! First, the sugar is beaten into the egg yolks with vanilla.

If you remember from the previous Bavarian cream blogs, you will know that this creates a “ribbon.”

✽ Step 2: Beat Egg Whites

Now for how you get the fluffy sponge- beating egg whites until soft peaks are formed which is always fun.

✽ Step 3: Fold Eggs with Flour

Very delicately, the egg whites and tepid, melted butter are folded into the egg yolk mixture.

It’s important not to overmix this step- you want the egg whites to retain as much volume as possible!

✽ Step 4: Turn Batter into Prepared Cake Pan

Biscuit au Beurre Recipe

The batter is turned into the cake pan and baked for about 30 minutes. You know the cake is done when it has puffed up, browned slightly, and the edges have pulled away from the sides of the pan a bit.

Now, Julia says that you can serve this cake just sprinkled with powdered sugar and with tea. She also suggests that you can fill and decorate as well which is the route I chose.

I decided to go with a chocolate icing decorated with chocolate chips. The chocolate-butter icing is actually the absolute last recipe in the book. It is very simple to make: semi-sweet baking chocolate, rum, and butter!

Overall, this was a delicious cake. I honestly think that I may have cooked it a tad too long as I was afraid it was not getting done so it was a little dry.

I am not a baker by any means, but I am learning.

The next dessert will be the next Bavarian cream! No more skipping around.
