My mom has a yummy Christmas dessert that she has been making since I can remember. Chocolate Mint Yule Log (I know, very 80’s). It’s a chocolate jelly roll filled with minty whipped cream and crushed candy canes, topped with chocolate ganache and more candy cane bits, and served semi-frozen.
And I cannot veganize it yet. I’ve been trying every few weekends for a while now.
Traditionally, jelly rolls are made with sponge cake sheets, as the high egg content makes them stretchy and a little less soggy upon prolonged contact with filling.
The first two attempts, I didn’t take photos. First, I tried mom’s recipe, which used both egg yolks and egg whites. I tried some weird custard powder-aquafaba-psyllium powder mixture from the yolk. The egg whites were made from Aquafaba with Xantham gum added in. I recall that this version stuck to the paper like the dickens, and had large holes. I figured I would next try something that didn’t require egg yolks.
So I tried a modification of a “hot milk sponge” recipe from Joy Of Cooking, with Aquafaba egg white whipped stiff, sugar whipped in, and then a dry mixture of flours and baking powder mixed in. The second version had no xantham gum added to the “eggs”, and fell flat while folding in the dry powders. It also was crunchy on the top once baked.
The third time, I called my gramma and got her recipe (similar to the Joy of Cooking one). It’s lemon, rather than chocolate, but I figured I’d start with the lemon recipe and go from there. It didn’t collapse when folding in the dry ingredients, but I had upped the Xantham gum. It stayed relatively high, but the op of the cake almost seemed caramelized. Once flipped over for filling, it was full of very large air holes.
A few nights ago, I tried gramma’s recipe again, but with some of the flour subbed out for cocoa, and I decided to follow the recipe more closely by using mostly granulated sugar instead of instant-dissolving sugar. However, I goofed and used four times the amount of hot milk – so the batter collapsed as soon as I added it. Undaunted, I baked it anyway, and was rewarded by a thin, gummy sheet. Mme. Minty tried it and said it gave her a stomachache.
I decided to take a different tack and try an already vegan recipe, and make it more like the cake I remember eating in years past. I took the “Wacky Cake” recipe from How it All Vegan and modified the oil and water ratios and added some psyllium powder. It’s a cake that uses leavening from vinegar and baking soda, in addition to baking powder. It baked into the perfect thickness. However, I tried rolling it up before it was cool enough, so it broke. I also think that I need to fold in a little bit of “egg white”, to give it a bit more elasticity.
So here I am, five cakes later and not as far ahead as I had hoped. At least the last attempt tastes and looks good; I just need to make it a bit more durable. Have any of you, dear readers, ever made egg-less sponge cake? Have any suggestions? I’m hoping to have a recipe up here soon that will actually work!!
