Material details: main ingredients: flour, right amount of ingredients, eggs, milk, a bag of chocolate milk tea, one or two bags of baking soda, right amount of dry yeast, right amount of cooking oil, right amount of pudding, right amount of sugar and milk powder. Manufacturing steps: 1. Melt the small pudding (the small pudding is rich in milk flavor and can be used instead of milk powder). Add milk to an egg in a bowl, and the dosage is about one-third of that of a bag (depending on how much you want to make, I think it is almost enough). There is no fixed standard when I make it, according to my own taste), add chocolate milk tea (milk tea is convenient to buy, and cocoa powder can be used instead of Gao Legao), add five spoonfuls of sugar, which can be more, stir well, then add half a spoonful of yeast and half a spoonful of baking soda, and then add half a bowl of cooking oil (butter will be better). 2. Add flour and knead the dough into a smooth dough. 3. The thickness is about 2mm. 4. Press the shape on the dough sheet with a mold. I use a bottle cap here. Actually, I don't have to buy molds. You can also use jelly shells (such as heart-shaped jelly shells, which can be used by cutting off the outside) to make larger bottle caps. 5. Put the decompressed dough pieces into electric baking pan in turn. 6. Punch a few holes in the dough with a toothpick. 7. The bottom is on fire. This is the most important step. After putting the dough into the electric baking pan, close the upper plate and fire at this time. 8. After about one minute of simultaneous firing, turn off the lower plate and only open the upper plate. If the lower plate is not cooked, it can be reheated, but the time should be short. Keep the upper plate baked on the fire for about ten minutes (depending on the maturity, it is basically enough for the biscuits to turn yellow, so always pay attention).
