What Ingredients Do Cookies Need? Absract In this experiment, cookies will be made but substituting certain ingredients. In separate batches instead of all-purpose flour, coconut flour willbe used, syrup instead of vanilla, yogurt instead of butter, powdered sugar instead of sugar, and cream of tartar instead of baking powder. The hypothesis is that the cookie with cream of tartar instead of baking powder would be the most different. It is also predicted that the cookie with syrup instead of vanilla would have no difference. The first hypothesis was not supported. The most different cookie was the cookie with yogurt. The second hypothesis was supported. The cookie with vanilla had no difference only that it was a bit chewier. Conclusion The original hypothesis was that the cookie with the cream of tartar was going to be the most different. The hypothesis was based on background research. Both baking powder and cream of tartar have the same acidic base. This hypothesis was not supported in the experiment. The cookie that was the most different was the yogurt cookie. This difference between the control cookie and the one with cream of tartar was that the experimented cookie was darker and harder. The yogurt cookies had a bubble on the top and were a lot lighter than the control. This hypothesis was made based on background research. Cookies need moisture and it was thought that melted butter and yogurt had the same consistency. Claim The evidence shows that if baking powder is replaced with cream of tartar that the cookie will neither feel or taste like a regular cookie. Reasoning After tasting the control and cream of tartar cookie, it was found that the experimented cookie was very crunchy like a normal cookie. Data Question Which ingredient used to bake cookies is the most important and least important? This asks which cookie ingredient including flour, baking soda, sugar, syrup, and butter will change the cookie if it is substituted with coconut flour, cream of tartar, powdered sugar, syrup, and yogurt. Hypothesis My hypothesis is that if I substitute syrup for vanilla then there will be little to no difference. I also predict that if I use cream of tartar instead of baking soda it will be the most different.
