Preheat oven to 350 °F. Line a baking sheet with parchment paper.
Mix the breakfast cereals, baking soda and vanilla powder together in a bowl. In a new bowl, mix the peanut butter, sugar and eggs for 3 minutes until the mixture is smooth. Take a wooden spoon and mix in the dry ingredients and the chocolate chips.
With a spoon, or by hand, roll 2 inch balls and place them 2 inches apart on the cookie sheet. Bake for about 8 to 11 minutes until the cookies show golden edges. Take out and let cool for a few minutes.
