短文改错 Yesterday my mother let me to help her make chocolate cookies. First we measure ingredients(配料). As soon as the butter was soft, we put them into a large bowl and mixed it with sugar. Next, she asked me to add eggs into the butter or sugar. Then it was time to adding flour. You must be careful that you don't add too many flour at one time or you'll cover everything in a white dust. Final, we added chocolate and some nuts. The mixture put on a cookie sheet with a spoon and twenty minute later, our delicious creations were ready. After taste some, I found that cookies taste the best when they are still warm.
