How to make
Combine the flour, sugar, cocoa and stir. Add the yoghurt, baking soda and then the oil and vanilla at the end.
Beat everything with a mixer. Bake in a preheated 360°F (180 °C) oven for about 40-45 min.
Once cooled, prepare the glaze from the rest of the ingredients and pour it over the fudge.
The fudge is ready once the glaze hardens well.
