CUPCAKES!!!!!!

By CD • Uncategorized • 16 May 2013

For our eat course we had to create a lab report. the purpose of this was to learn about different chemical reactions of food. We made cupcakes and we had to substitute an important missing ingredient, baking soda. to find out what ingredient I used you can see the results in my lab report.

 Introduction/Purpose

The purpose of this project is to find an alternitive leavening agent in a cupcake recipe by having a basic and an acidic ingredient. In order to replace baking powder I looked at the pH scale and picked one basic and one acidic ingredient. I picked olive oil as my basic substituted ingredient and it has a pH of 8. for I picked applesauce for my acidic ingredient it has a pH of 3.5

 

 

Objective/Research Question

My guiding question is What happens when you replace baking powder to olive oil and applesauce in a recipe?

 Hypothesis

If I mix apple sauce with oil then they will react and make a leavening agent.

Materials Materials/ Ingredients for one cupcake:

  • 1/12 Cup sugar

  • 1/24 Cup butter

  • 1 Egg

  • 1/6 tsp Vanilla extract

  • 3/24 Cup all-purpose flour

  • 1 3/4 tsp Baking powder

  • 1/24 Cup milk

Replacement:

  • 1/4 Olive oil

  • 1/2 Applesauce

Materials:

  • Oven

  • Cupcake Pan

  • Measuring Spoons

  • Mixing Bowl

  • Measuring Cup

  • Whisk

  • Spatula

Procedure

 

  1. In medium bowl, cream together the sugar and butter

  2. Beat in the eggs, one at a time, then stir in the vanilla

  3. Combine flour and baking powder, add to the creamed mixture and mix well

  4. Finally stir in the milk until batter is smooth

  5. Pour or spoon batter into the prepared pan

  6. Add the leavening agent into each cupcake spot(for experimental group only)

Conclusion

My cupcake experiment with the leavening agents I predicted was wrong, but it had a great taste. My cupcakes had sunken down from the center instead of rising. I would not make the cupcakes again. If I were to do this over I would change the leavening agents I picked.
