After a heavy Christmas dinner, I love offering something that is lighter on the palate, which is why I serve this cake for my family. It's a light and airy chocolate sponge cake and don't worry about any cracking, because for this cake it's a good thing! And to give it that winter look, top with tanghulu, or sugar syrup covered fruit.

Measure by weight, if possible.

Measuring by weight is the best way for you to replicate my recipes. I develop recipes using ingredients (even liquids) measured in grams, which is why you see them listed first in the recipe cards. For measurements under 5 grams, I will typically only list the volumetric measurements (teaspoons, etc.), as most home scales are not precise for such small weights.

In most cases, I have converted grams to volumetric measurements (aka US customary units) for bakers who prefer this method. However, the measurements are not as precise and may have awkward proportions. The recipes should still work, but for the ultimate precision, try to use weight.

This is the OXO scale I use daily. I also purchased this budget version of a good scale, which I keep at my Mom’s house for baking. If you’re interested in other tools I use for my baking, I’ve compiled a list here.

Use room temperature ingredients.

All my ingredients should be used at room temperature, or 65-75 °F/18-24 °C. I will always indicate if you need something outside this range. If no details are given, room temperature is the default. 

Pay attention to the ingredient descriptions.

I try not to be brand-specific, but I will always note an interesting result from a type of ingredient, be it negative or positive. 

A specific note regarding salt: I use Diamond Crystal Kosher salt for everything on this site except for frostings. In frostings, you want the salt to dissolve more easily, and kosher salt tends to leave granules behind. If you substitute table salt (more finely granulated) for recipes that list kosher salt, you must use half the volume indicated in my recipes.

Substitutions are hard.

That’s not to say they’re impossible, though. For instance, in many cases, substituting reduced fat for whole milk (and thus reducing fat by less than 2%) will probably be fine. Using applesauce for oil or even Greek yogurt when sour cream is listed will definitely alter the fat content and adversely affect the crumb texture and density of the cake.

I experiment for hours to get these recipes to work for us. First, try to make them as written or use one of my tested substitutions, which I often dedicate a section to. Then, if necessary, you can make modifications afterward. Even then I would be pretty cautious, as substitutions are one of the hardest things to investigate in recipe development.

Read all the recipe instructions before beginning.

I’m in the “Pre-read the Chapter before Class Lecture” club... and I invite you to join! Baking new recipes can be intimidating, so let’s set you up for success. I want you to think about timeframes. Most fillings and frostings can be made ahead of time, and give you an extra day for mental space. Also, as you become a more proficient baker, you can anticipate and recognize steps. (“Oh, this has a meringue step, so I’ll need an extra clean bowl…” etc.) Ensure you go down the ingredient list and have everything at the right temperature.

  • 2 TB granulated sugar
  • 1/2 tsp gelatin powder (optional)

Instructions

Bake the Cake

  1. Preheat the oven to 350 degs F and place a rack in the middle of your oven.
  2. Butter and flour a half sheet pan and line the bottom with parchment paper.
  3. Pour about 1-2 inches of boiling water into a large bowl.
  4. In a mixing bowl, add your eggs and granulated sugar, and place the mixing bowl into the bowl containing the bowling water.
  5. Use a whisk to mix the eggs until they loosen slightly and is warm to the touch, for about 2 minutes. (It should be between 90-100F, but you can use you fingers to feel that the sugar is dissolved the the mixture is around body temp, but no hotter.)
  6. Immediately transfer the mixing bowl to the stand mixer and whisk on medium-high speed for 5 minutes. It should be pale yellow, thicker, and very shiny.
  7. Meanwhile, sift the cake flour, cocoa powder, baking powder, and salt in a small mixing bowl.
  8. When the egg-sugar mixture is ready, remove from the stand mixer and gently pour in your dry ingredients. Fold in using a large spatula.
  9. Add a couple spoonfuls of the batter into another small bowl containing the oil and mix until combined.
  10. Pour the oil mixture into the main batter bowl and fold until combined.
  11. Pour batter into prepared half sheet pan and bake for 18-22 minutes or the cake springs back lightly to the touch.
  12. Let the cake cool to touch in the pan and follow the instructions in my tutorial for folding and filling the roll.

Make Tanghulu fruit

  1. Add sugar and water to a small saucepan and boil until it reaches the hard crack stage: 300-310 degs F.
  2. Skewer the large fruit and carefully dip into hot sugar syrup.
  3. Allow to dry by poking skewers in styrofoam or my laying on a nonstick baking mat.

Make Whipped Cream

  1. If using the gelatin, pour 1 TB of cold water into a small microwavable bowl. Sprinkle on the gelatin powder and set aside.
  2. Pour the heavy whipping cream and sugar into a chilled mixing bowl and mix on medium speed for about a minute.
  3. Microwave the gelatin for about 8-10 seconds until liquid.
  4. Increase the mixer to high and when it reaches soft peaks, pour in the gelatin.
  5. Mix for another 20-30 seconds until slightly more firm, but still very soft and creamy.
