Mini vegan cakes truly have my heart. So delightful to make and enjoy, so tiny and cute. And if they are full of homemade jam, even better.
When I was a child, there was a specific snack bar that I adored. Two layers of a simple vanilla sponge and a layer of marmalade between them. Given that jams have been one of my greatest loves since childhood, it was not a surprise that I loved those little snack bars.
They've been discontinued a long time ago and even if they were still being produced, I am quite sure the sponges were egg-based so it would not align with my preferences now, so I took it upon myself to bring them back in a way that is much more fitting for who I am today.
Four vegan vanilla sponge layers and three layers of homemade mandarin orange and lime jam. Absolute perfection all on its own, but even better with a crunchy chocolate glaze.

Ingredients
For the soft vanilla cake layers
180 grams plain flour200 grams granulated sugar
1 teaspoon baking soda
1/8 teaspoon baking powder
1/2 teaspoon salt
1 teaspoon apple cider vinegar
2 teaspoons vanilla bean paste
45 millilitres neutral oil
240 millilitres carbonated water
For the mandarin and lime jam filling
400 grams fresh mandarin orange segments200 grams apples, grated
50 grams lime segments
300 grams granulated sugar
1/2 teaspoon vanilla bean paste
2 teaspoons apricot brandy
For the dark chocolate glaze
70 grams dark chocolate (60%)20 millilitres neutral oil
30 grams flaked or crushed almonds

Preparation
Start by making the jam filling, because it needs time to cool down. Grate the apples and squeeze them dry, and add them to a heavy saucepan or a small cooking pot. Segment the mandarin oranges and limes, remove any pips, and add them to the apples. Finally, tip in the sugar and mix everything thoroughly. Place the pot over medium heat, and let it very slowly come to a boil. As soon as it starts to bubble, start the timer, and cook for about 30 minutes, stirring often. As this is a small batch of jam, the cooking process is quick.
After about 30 minutes or so, purée the jam completely with an immersion blender, and cook for 10 minutes more. At that point, check to see if it has reached the setting point, either by dropping a teaspoon of it onto a chilled plate, and seeing if it sets after about a minute, or by inserting a candy thermometer and making sure it has reached 90-95°C. If not, continue cooking and checking in 2-minute intervals until set. The longer you cook it, the deeper the colour and flavour will get, but it will also be much more difficult to spread and slice the cake. Once the jam reaches its setting point, remove it from the heat, stir in the vanilla, and let it cool down completely. You should get around 400-420 grams of jam.
Next, make the vanilla cake layers. Let the oven preheat to 180°C and line a medium square cake pan (18x18 cm) with baking paper, bottom and sides. Take a medium bowl and sift in the flour, baking soda, and baking powder. Add in the sugar and salt, and mix well. Finally, in no particular order, pour in the carbonated water, oil, vanilla, and vinegar, and whisk until combined. As soon as the batter is ready, pour it into the prepared pan, and bake immediately in a preheated oven, at 180°C, for about 20 minutes or so, checking for doneness early on. As soon as a toothpick inserted into the centre comes out clean, the cake is done. Remove from the oven and let it cool down a bit in the pan.
My cake was done after exactly 21 minutes.
Once the jam has cooled down almost fully and the cake is still slightly warm to the touch, proceed to assemble the cake.
Level the cake if needed, slice it in half lengthwise, to create two thin strips of cake, and then cut each of them in half to create four very thin layers. Weigh the jam you previously cooked and separate it into four parts. Three of them should be 100 grams each, while the fourth one can be whatever is leftover.
Place the first cake layer on the serving platter, and add 100 grams of jam. Place another cake layer on top, and keep repeating the process until all the cake layers are used up.
If your jam is too thick or has gotten very cold, you can add it to a piping bag and simply pipe the jam in a single layer onto the cake.
Add the apricot brandy to the remaining jam, and heat it very lightly, to make it additionally spreadable, and then use it to frost the cake on all sides. Place in the refrigerator for at least 2-3 hours.
Once the cake has set, melt together dark chocolate and oil, either over low heat or in the microwave, and mix it very well. Just before glazing, add in the flaked or crushed almonds, and glaze the cake on all sides, covering all of the jam. Return it to the refrigerator for at least 8 hours, and then serve as desired. Yields 12 rich servings.
