Hey!
Today I'd like share recipe for this yogurt based cake, that is a variation of cottage cheese cake I posted some time ago, slightly different here and there, but follows same logic and utilizes same techniques and tricks.
A. Cake Base (132 kcal / 4g protein / 0g fat / 28g carbs / 1g fiber)
2g Instant Coffee (I use spray dried decaf)
10g Granulated Erythritol Sweetener
0.5 Xanthan Gum
35g Water
30g AP Flour
6g Cornstarch
2g Baking Powder
0.3g Salt
35g Water
Sweetener and other flavorings to taste (I used 1.5 ml saccharin based sweetener, no vanilla or any flavor drops this time, but do at other times)
I make quite a few variation of cake bases following this same logic (whip something and then fold in flour and bake), this one is the lowest in calories that I have, but also is trickier to make than most others and, well, it might have slight hint of coffee to it! Speaking about tricky, this time top cracked for me. Does not happen always, but happens, maybe I failed at combining properly, or temperature was not right (it is hard to control in my ancient gas oven). However, it all will be filled by filling anyway, so does not matter that much in the end.
If you want some other variations that don't involve coffee, refer to my cottage cheese cake posts. There is whipped applesauce, egg and yogurt versions in posts and/or somewhere in the comments.
So, pre-heat oven to ~170C.
Pre-mix coffee, erythritol, xanthan gum, add water, mix well and set aside. This stuff needs to hydrate a little.
In other bowl pre-mix flour, starch, baking powder, salt and any other dry things if using (sweetener/flavorings) then add water and liquid sweeteners/flavorings, mix well and set aside.
Back to coffee mixture, use electrical whisk to whip it until very stiff peaks, it should become very pale and airy. Then using spatula fold this foam into batter, goal here is to find balance between combing both well, yet not overdoing it to not deflate it. Unlike egg whites or aquafaba, coffee based whip is very unstable and time works against us.
Once done combining, transfer it to cake mold/springform and bake ASAP at around 170C for 25-30 min.
Remove it from mold and let it cool on a wire rack.
B. Jelly (23kcal / 0g protein / 0g fat / 3g carbs / 2g fiber)
1.5g Agar-Agar powder
150g Water
Sweetener, Flavor Drops, Coloring to taste (I used 6 tablets of saccharin based sweetener, 3 strawberry flavor drops and some red coloring)
45g Defrosted Frozen Strawberries
Slice defrosted strawberries and put them inside same/identical cake mold as before, in a small pot/sauce pan add agar powder, sweeteners, flavor drops, coloring (I also added liquid that was left from defrosting strawberries) then add water, mix and bring to boil while stirring and then let it simmer for half a minute or so. Pour into the mold and let it set for like 30 minutes or so. If you only have one mold, this jelly layer can be done before or after cake, doesn't matter much. Once set, carefully extract it and put aside.
C. Yogurt Filling (209 kcal / 21g protein (including gelatin) / 6g fat / 18g carbs / 0g fiber)
200g Plain Yogurt (Mine was 3% fat)
10g Gelatin
50g Water (for blooming)
10g Cornstarch
30g Water (for starch slurry)
70g Water (for "syrup")
Any sweetener, flavorings, coloring etc to taste (I used 8 tablets of saccharin based sweetener, 2 flavor drops, this time it was apple flavor for no big reason)
Bloom gelatin in 50g water for about 10 minutes, separately combine starch with 30g water, then combine other 70g water with your sweeteners and flavorings (lower water accordingly if using syrups), bring this to simmer and while stirring, add starch slurry and keep stirring on low heat for around a minute. Add this goo to bloomed gelatin and stir until gelatin is dissolved. Whip with electric whisk until it is very very thick, yet pourable foam, then add yogurt and whisk on low speed for a little bit more, just until it is incorporated.
D. Assembly
Put cake base back into mold, if it is tall enough - one I used this time is not tall, so I wrapped silicone cake ring around base instead. Pour yogurt mixture over cake base, shake it bit so it is distributed more evenly, then carefully put jelly layer on top. Let fully set in the fridge for at least 2 hours, or better 3 for good measure. Carefully extract your cake from mold/ring
Done!
