Hello my dear Steemians, excited to participate for the first time coach challenge 
2½ cups of Greek yogurt
2 cups of wheat bran. You can also use 100 grams of Corn Flakes cereals, bran
oatmeal or oatmeal
½ cup of hazelnuts or 60 grams of nuts of your choice: nuts, almonds.
⅓ cup of egg whites.
10 grams of neutral gelatine leaves (Do not get complicated, see the total grams that the package brings and how many sheets, rule three and you're done)
Stevia (sweetener) or sugar if you do not mind using it.
Fruit jam. You can try strawberry or orange
Preparation
First crush the wheat bran or cereal with the hazelnuts or dried fruit you have chosen and 1 or 2 tablespoons of Stevia or sugar. You can do this in a blender or processor.
Place the mixture in a bowl, add the whites and knead until it forms a lumpy mass that compacts when pressed. If you use cereals or oatmeal, and you need to add more whites, go ahead; the important thing is that the dough is compacted easily, as if it were wet sand.
In a silicon container expand the mixture evenly to assemble the base and walls of the cake, and put it in the oven at 180 º C for 15-20 minutes, until the base is like a cookie.
Meanwhile, place the gelatin sheets in a container with cold water for 5 minutes or as indicated by the manufacturer's instructions. The sheets will soften and grow.
Boil a little water, add the leaves of the jelly and stir until it dissolves. If it is the first time that you use sheets of gelatin, as it was my case, it is important that you take literally the "measure" of little water (one or two fingers). This mixture will serve to give consistency to yogurt, so if we use a lot of water it will be very complicated to set.
In a separate bowl mix the yogurt with stevia to taste, and add the water with the gelatin sheets. When the base is baked and crunchy add the yogurt mixture and bring to the refrigerator, at least for two hours.
Once the yogurt cake is cold and consistent, cover it with the jam of your choice; It will be easier for you if the jar of jam is at room temperature. You can also cover it with strawberry syrup, or whatever you want.
