Gluten Free Black Forest Cake

My version of Black Forest cake is quite different, compared to many gluten free adaptations of this popular German cake. Chocolate sponge in this cake is soft, moist and has a deep dark chocolate taste, but is it made from unusual list of ingredients, without chocolate, butter or any other added fats. Sour cherries layer is made from frozen sour cherries, cooked with only half quantity of sugar, usually used for cherry jams. For the cream layers I used my rich vanilla cream, made as a mixture of thick pastry cream and whipped cream with the addition of leaf gelatine. I bake chocolate sponge layers in my new, unusual in shape, spingform pan, but sponge layers can be baked in regular round pans, as well. And finally, for cake decoration I used fresh cherries, ground sponge crumbs, and new for me chocrocks, instead of chocolate shavings.

I made this cake for our Christmas lunch this year. For every chocoholic this cake is the answer to their cravings. Intense dark and bitter chocolate taste is balanced with silky vanilla cream gentle sweetness with Calvados flavour, complimented with tart and juicy whole sour cherries. It was perfect for my husband, who adores dark chocolate. For my taste it was a touch too bitter, and needed some extra whipped cream to be served with.

With vanilla cream, soft, but dense enough to keep its texture, the cake was very easy to cut. The cream was not squeezed out from the cake, as it often happens with whipped cream in sponge layered cakes.

Ingredients:

chocolate sponge

Ingredients are given for one individual layer, each layer is baked separately. It is possible to prepare the batter for 3 layers and bake them in a thin layer on a large flat cookie tray and then cut the sponge in 3 pieces. I had 4 sponge layers in my cake, just because I wanted to be sure that I will have enough off-cuts from the sponge to make crumbs for cake sides decoration.

  • 1 large egg
  • 100g pure apple puree (I used blended commercial apple pie filling)
  • 50g sugar
  • 20g cocoa powder
  • 60g almond meal
  • 3g baking powder (1/2 tea spoon)

When using raw cocoa powder you can use either baking soda or baking powder, with Dutch cocoa powder, darker in colour, only baking powder will work as a raising agent.

sour cherries

  • 500g frozen sour cherries (I got them from our greengrocer), alternatively you can use canned Morello Cherries in liquid with 14% sugar, not in syrup
  • 200g sugar for frozen cherries
  • for canned Morello cherries use 100ml liquid and 50g sugar

Tart cherries from frozen sour cherries.

Sour cherries can be prepared well in advance, vanilla cream have to be prepared the day before cake assembly.

  • add sugar
  • the sugar will dissolve while cherries defrost
  • cook on medium heat until boiling point and 10 minutes after that
  • let the cherries cool
  • repeat the process and cook cherries until very little thick syrup is left (I was left with 50 ml of sour cherry syrup)
  • to prepare sour cherries layer I cut baking paper to the size of the cake and placed cherries to make this layer, covered it with baking paper and kept refrigerated for several days

vanilla cream

  • prepare vanilla cream as described here
  • refrigerate cream overnight

chocolate sponge

  • chocolate sponge preparation with step by step photos can be found here

  • place cut-offs on a tray and bake 15 minutes in 150C oven, they have to be completely dry

Vanilla cream performed even better than I expected. Christmas day was hot and the cake stood for 4-5 hours at 26C temperature with high humidity, but the cream kept its shape and texture and did not melt. Chocrocks also did not melt into the cream, and even with the high moisture in the house, kept their shape and gloss. The cake kept its taste and texture well when stored refrigerated under the dome of aluminium foil, cake slices in the photos were done with the last pieces of the cake on the New Year eve.

You can make this cake in a more simple way by using thick tart cherry jam and whipped cream, I can only say, that apple puree and cocoa powder sponge, made with almond meal as dry ingredient, is the most essential component in this delicious light cake, made without butter. It is my way of getting an intense and memorable flavour without cake being rich and heavy. The taste and texture only win with these unusual, but simple ingredients.

  1. That really looks like a work of art. Beautiful! You’ve really done so many amazing things with a simple thing like apple purée. Which, if it wasn’t for you, I wouldn’t have even thought of using outside of tart fillings. I appreciate all your hard work.

    1. Thank you all fruit and vegetable puree recipes were born out of simple idea from almond and orange cake. From orange puree I jumped to apple puree, and from apple puree to fresh apple. Did not even know all the qualities of apples in baking. Now I use apples, cauliflower, beetroot in baking and cooking every day. This chocolate sponge in so light and moist, and is so easy to make, that I will never go back to anything else.
