Woody's Chocolate Curls Marble Butter Cake



Serves: 12 to 15
Oven Temperature: 350˚F/175˚C
Baking Time: 50 to 60 minutes

 Radio talk host, Joan Hamburg, reminisced to us about a marble cake her mother would make in the 1950s that had chocolate curls, when we did a podcast interview on her radio show for Rose’s Baking Basics. We have mixed in mini chocolate chips into cake batters. So I took up the quest to see if incorporating chocolate curls would work with our Rose’s Baking Basics Marble Cake. To lighten the color of the non-chocolate batter, I substituted whole eggs for the egg yolks.

I also have included TIPS on how we test a recipe and make cakes.

 TIP: READ the RECIPE in its entirety and re-read any sections so that you are comfortable with carrying out the recipe.

Special Equipment One 12 to 15 cup metal fluted tube pan (see Notes), coated with baking spray with flour.
TIP: Nordicware’s Anniversary 10-15 cup cast aluminum pan works well.

TIP: Add up the gram weights of the recipe’s ingredients, taking in account if an ingredient is reduced in the recipe. Weigh the finished batter, which should only be less by 3-5%. This batter is 1412 grams.

Preheat the Oven
* Twenty minutes or longer before baking, set an oven rack in the lower third of the oven.
* Set the oven at 350˚F/175˚C.

Set Up for Ingredients (Mise en Place)
assemble all of the ingredients, measuring apparatus, and likely tools you will need.
This will help to make sure that all of the ingredients are used.

* 30 minutes to 1 hour ahead, set the 50% to 55% dark chocolate, butter and eggs on the counter at room temperature (65˚ to 75˚F/19˚ to 23˚C).

Make the Chocolate Curls
* Set a block of chocolate in a warm place, under a lamp, or warm it with 3 second bursts in a microwave, turning it over several times.
* Place a quarter sheet pan or small cookie sheet on a counter top or on a scale if weighing.
* Use a paper towel to hold the chocolate and a sharp vegetable peeler to form the curls. Start at the upper edge and bring the peeler toward you. Firmer pressure will form thicker curls, allowing them to fall directly onto the sheet pan. (1/16 inch thick curls work well.)

 Melt the Chocolate
* About 30 minutes ahead, melt the chocolate: In a small microwavable bowl, stirring with a silicone spatula every 15 seconds (or in the top of a double boiler set over hot, not simmering, water, stirring often—do not let the bottom of the container touch the water), heat the chocolate until almost completely melted.
* Remove the chocolate from the heat source and stir until fully melted. Let it cool until it is no longer warm to the touch but is still fluid.

 Make the Batter 
TIP: Grade A large eggs frequently weigh more than 50 grams per egg, in which the extra weight is egg
whites. We will use the egg’s shell to remove the extra whites.

1) Into a 2 cup or larger measure with a spout, weigh or measure the eggs. Add 60 grams/1/4 cup of the sour cream, and the vanilla and whisk just until lightly combined.
TIP: if the liquid ingredients will be left uncovered for more than 10 minutes, cover them with plastic wrap to
minimize evaporation.

2) In the bowl of a stand mixer fitted with the flat beater, mix the flour, sugar, baking powder, baking soda, and salt on low speed for 30 seconds.
TIP: if you have had batter jumping out of the bowl, you can drape plastic wrap over the bowl and attach it
to the mixer.

3) Add the butter and the remaining sour cream and holding the beater with your hand, mash the butter and sour cream into the flour mixture so that it doesn’t jump out of the mixer when beating. Then mix on low speed until the dry ingredients are moistened. Raise the speed to medium and beat for 1-1/2 minutes. Scrape down the sides of the bowl.
4) Starting on medium-low speed, gradually add the egg mixture to the batter in two parts, beating on medium speed for 30 seconds after each addition to incorporate the ingredients and strengthen the structure. Scrape down the sides of the bowl.
5) Remove almost one third of the batter (354 grams/1-1/2 cups) to a bowl and stir the melted chocolate into it until uniform in color.
TIP: you can also use a hand mixer on medium speed.

Assemble the Batter and Curls
for bundt and tube pans, putting a foil “cap” over the center tube will keep batter from going down it.
Remove it before baking.
TIP: if you are weighing your ingredients. Tare out the weight of the pan. You can tare out as you are adding
the batter and curls. Check the weight at the end to compare it to the 1412 grams for the chart to make
sure you did not forget an ingredient.

6) Spoon one-third of the plain batter into the prepared pan.
7) Sprinkle one-third of the chocolate curls on top (preferably the smaller ones and pieces). With a regular tablespoon, lightly fold and swirl the curls into the batter.
8) Top with dollops of half the chocolate batter. Spread it gently but evenly.
9) Top with another one-third of the plain batter and another one-third of the chocolate curls. Lightly fold and swirl the curls into the batter.
10) Top with dollops of the remaining chocolate batter. Spread it gently but evenly.
11) Top with the remaining plain batter and chocolate curls spreading them evenly over the top.
12) Marbleize the entire batter lightly: Dip in the tablespoon, without touching the bottom or sides of the pan, and lift up the batter in a folding motion like the roll of a wave. Repeat this motion 3 to 4 times, all around the pan. Smooth the surface.

Bake the Cake
13) Bake for 50 to 60 minutes, or until a cake tester inserted between the tube and the side comes out clean and the cake springs back when pressed lightly in the center. The cake should start to shrink from the sides of the pan only after removal from the oven.

Cool and Unmold the Cake
we write our testing notes on pre-made cards that we photograph with our baked items as an easy
way to refer back to a test, especially if it was a success.

14) Let the cake cool in the pan on a rack for 10 minutes. Use a small sharp knife to dislodge the cake inside the rim of the pan. Loosen the cake by jiggling it up and down until it moves slightly. Invert it onto a wire rack, coated with cooking spray. Cool until lukewarm.
15) Wrap the entire cake with plastic wrap. This will keep the cake moist.
16) Serve when completely cooled. (Alternatively: If you are serving thin 1/2 inch wide slices, it is best to refrigerate the cake and cut it when cold out of the refrigerator. )

 Store Airtight: room temperature, 3 days; refrigerated, 1 week; frozen, 3 months.

* A 10 cup bundt pan can be used. The cake will rise above the center tube during baking. Depending on the pattern of the pan, the bottom edge of the cake may break off in places as you are cutting it, OR remove some batter for make 2 cupcakes to bake for 20 to 25 minutes.
* I used Valrhona Caraque 55% 1/2 inch wide block chocolate for the curls.
