Bake Gingerbread Cookies
Why not bake a batch of cookies and experiment with the ingredients? What happens when you leave out the baking soda? This article has some great information to share with the kids as well as show you how you can conduct a science experiment.
Simple Gingerbread Man Cookie Recipe
Here’s a simple and kid-friendly gingerbread man cookie recipe with a minimal number of ingredients that my grandma would always make.Don’t forget to read about the science below.
Ingredients:
- 3 cups all-purpose flour
- 1 teaspoon baking soda
- 1/4 teaspoon salt
- 1 tablespoon ground ginger
- 1 tablespoon ground cinnamon
- 1/2 teaspoon ground cloves
- 3/4 cup unsalted butter, softened
- 3/4 cup brown sugar, packed
- 1/2 cup molasses
- 1 large egg
- 1 teaspoon vanilla extract
- Optional: Icing and assorted decorations for decorating the cookies
Instructions:
- Preheat the Oven: Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper.
- Combine Dry Ingredients: In a medium bowl, whisk together the flour, baking soda, salt, ground ginger, ground cinnamon, and ground cloves. Set aside.
- Cream Butter and Sugar: In a large bowl, cream the softened butter and brown sugar until light and fluffy.
- Add Wet Ingredients: Add the molasses, egg, and vanilla extract to the butter-sugar mixture. Mix until well combined.
- Combine Wet and Dry Ingredients: Gradually add the dry ingredient mixture to the wet ingredients, stirring until a dough forms.
- Chill the Dough (Optional): If the dough is too soft, refrigerate it for about 30 minutes to make it easier to handle. This step is optional, especially if you’re working with kids and want to speed up the process, but it can also make the cutting process less frustrating.
- Roll and Cut Out Shapes: Roll out the dough to about 1/4 inch thickness on a lightly floured surface. Use gingerbread man cookie cutters to cut out shapes.
- Bake: Place the cut-out shapes on the prepared baking sheets and bake for 8-10 minutes or until the edges are lightly browned.
- Cool: Allow the cookies to cool on the baking sheets for a few minutes before transferring them to wire racks to cool completely.
- Decorate (Optional): Once the cookies are completely cooled, you can decorate them with icing and assorted decorations.
Gingerbread Cookie Science Information
Baking cookies involves a combination of chemical and physical changes. The initial mixing of ingredients represents a physical change, as components like flour, sugar, and baking soda retain their chemical properties while combined.
However, chemical reactions occur once the dough is placed in the oven. Baking soda, a leavening agent, undergoes a chemical reaction with acidic components in the dough, producing carbon dioxide gas that causes the dough to rise, a clear example of a chemical change.
Overall, the process of making cookies encompasses physical changes in the mixing phase and chemical changes during the baking phase, resulting in the delicious treats we enjoy.
As kids decorate the cookies, they further explore principles of color mixing and creativity, merging art with science in a delicious and educational experience.

Gingerbread Man STEM Challenge
Design and create a structure or device to help the gingerbread man safely cross a “river” (a designated area) without getting wet. Suggested supplies are:
- Gingerbread man cutouts (or any small, lightweight objects to represent the gingerbread man)
- Craft supplies (such as popsicle sticks, straws, tape, paper, cotton balls, foil, etc.)
- Containers of water (to represent the “river”)
- Other building materials or tools deemed suitable and safe for the challenge
Build A Gingerbread Man Tower
Build with gingerbread man cookies! Grab a can of icing and a bag of crispy gingerbread man cookies. Can you make a tower? Of course, you can’t forget about building gingerbread houses as an amazing STEM activity for the holidays.
5 Senses Gingerbread Tasting
Cookie tasting is excellent for learning about the 5 senses. If you can find a variety of cookies from crispy to chewy, you can set up an excellent cookie tasting for the 5 senses. Your experiment can include taste, touch, smell, sight, and sound {think about munching and crunching}. See our 5 Senses Chocolate Challenge!
