In the video, a person is seen using a stand mixer to mix a chocolate batter. The mixer is set on a wooden table and is in motion, with the beaters spinning rapidly. The person then pours a bowl of flour into the mixer, which is already filled with the chocolate batter. The flour is poured in a steady stream, and the mixer continues to mix the ingredients. The person then uses a red spatula to scrape the sides of the bowl and ensure that the flour is evenly mixed with the chocolate batter. The video ends with the person continuing to mix the ingredients using the spatula.
