Recipe for Yule Log Cake with Custard

20151224_210207_thumb26

I made a Yule Log Cake (in French, Bûche de Noël) this year for dessert on Christmas! It was a yellow cake with custard inside and chocolate ganache icing on the outside. You can make one too! 

The Yule Log Cake (Bûche de Noël) is a traditional dessert that’s served for Christmas in France and Quebec.  Recently, people also make it in the U.S. and Britain. It’s traditionally a rolled up cake with a filling inside and icing on the outside. The rolled up cake gives it the shape of a log.yule log cake

The Yule Log Cake is meant to resemble an actual Yule Log. The Yule Log is a specially chosen log that’s traditionally burned on the hearth on Christmas in many countries in Europe.

Decorating Yule Log Cakes

Yule Log Cakes are often made to resemble an actual log. For instance, mine had "mushrooms" made of marzipan on top. Other people make mushrooms out of meringue. I saw one that had green matcha powder sprinkled on top to look like moss!

One idea is to put some raspberries on top. You can also sprinkle confectioner’s sugar on top to look like snow. It looks pretty!

Timing

Yule Log Cakes take some time to prepare.  I recommend making the custard filling and the ganache icing two days beforehand and refrigerate them. Then the cake can be made the day before and you can put it all together and decorate it. Refrigerate the cake until serving.

20151224_150701To Make the Cake…

Preheat the oven to 350 F.

1. Butter a 15 x 10 x 1" baking sheet. Cut a piece of parchment paper to fit the bottom of the pan (it’s okay if it’s a little short on the edges). Then butter the top of the parchment paper while it’s in the pan.20151224_154800

2. In a bowl, sift together the cake flour, baking powder and confectioner’s sugar and mix. Set aside.

3. Beat together the egg yolks with 1/2 cup sugar and the vanilla on medium high speed until thick. Mix in cooled, melted butter. Set aside.

4. In a metal bowl, beat egg whites, cream of tartar and salt on medium speed until soft peaks form. Add 1/3 cup of sugar and beat until stiff peaks form.20151224_160958

5. Fold the egg white mixture (from step 4) into the egg yolk mixture (from step 3).

6. Fold sifted flour mixture (from step 2) into egg mixture (from step 5).

7. Pour the batter into the prepared baking sheet (pan) until evenly distributed.20151224_162802

8. Cook for 12 – 15 minutes until the middle is springy to the touch.

9. Get a very clean kitchen towel that’s bigger than your cake. Sprinkle confectioner’s sugar on it.

10. Take a knife and go around the edges of the cake to loosen it.20151224_162943

11. Turn the pan upside down on the towel. Peel off the wax paper.

12. Roll the cake with the towel until it’s fully rolled up. Place on a rack to cool. This makes the cake more pliable later so you can roll it up with a filling without it breaking.

To Make the Custard Filling…

1. Slowly bring the milk, heavy cream and 1/4 cup of sugar to a boil over medium heat in a small saucepan.

2. Meanwhile beat together the 2 yolks and the egg in a bowl.20151224_172639

3. Whisk in the cornstarch and 1/3 cup sugar.

4. Slowly add the milk/cream mixture (from step1) into the egg mixture. Then pour it all back into the saucepan.

5. Bring to a low boil, stirring the mixture continuously. Once it thickens, remove from heat.

6. Then mix in the melted butter.

7. Set aside to cool and refrigerate the custard if you’re making it in advance.

To Make the Chocolate Ganache…

1. Heat up the heavy cream in a small saucepan.

2. Add the chocolate and stir. Take off the heat.20151224_193213

3. Mix until the chocolate is smooth and melted.

4. Put in a bowl and set aside to cool. 

5. If you’re making it with the bark, let it cool enough so that it stays on the cake. If you’re skipping the bark and using the ganache like icing, let it cook longer until thicker. Once it’s thicker, beat with a mixer for a minute or two until fluffy. 

If you make the ganache a day ahead of time, you should refrigerate it. Then take it out in advance to warm up.  You can warm it in the microwave for 10 seconds at a time.  If it gets too soft, let it sit until it hardens a bit.

To Make the Chocolate Bark (Optional)…20151224_201702

1. Line a cookie sheet with parchment paper

2. Place the chocolate chips in a bowl over hot water until melted.

3. Spread the melted chocolate on the parchment paper until it’s about 1/8" thin.

4. Refrigerate until set. You can put it in the freezer for about 10 – 15 minutes to speed up the process.

5.  Once it’s set, tear off 1" wide strips of chocolate. They can be different lengths to make the bark look more natural.

6. Set aside.

To Make the Marzipan Mushrooms (Optional)…

1. Open the tube of marzipan. 20151224_201522

2. Make 1" balls (corresponding to the number of mushrooms you want to make). Roll the same number of mushroom stems.

3. Make hole in the ball with your finger and shape the ball to look like a mushroom. Push a stem into the indentation of the ball.

4. Roll in a little cocoa powder to give it a natural look.

5. Make all the mushrooms this way.  Set aside. 20151224_193933

To Assemble the Yule Log Cake

1. Unroll the cake. Take about 1 3/4 cups of the custard and spread it on the unrolled cake. (Don’t put too much custard or it will come out the sides of the cake when you roll it up.)

2. Roll the cake up (without the towel this time).  Place on a platter. 20151224_200527

3. If desired, cut off a slice from the end of the cake that’s about 11/2" thick. Spread ganache on the cake where you’re going to place the slice (off-center is better). Place the slice on top of the cake. This will make it look like a branch was cut off the log.

4. Spread the ganache over the cake, covering the whole thing.

5. If desired, place pieces of the chocolate bark over the ganache in a natural pattern.20151224_203303

6. If desired, sprinkle a little cocoa powder over the chocolate bark to make it look more natural.

7. If desired, place mushrooms on the cake.

Enjoy!
