Ingredients for Rainbow Cookies
For the Cookie Layers:
- 1 cup (2 sticks) unsalted butter, softened
- 1 cup granulated sugar
- 4 large eggs
- 1 teaspoon vanilla extract
- 1 teaspoon almond extract
- 2 1/2 cups all-purpose flour
- 1/2 teaspoon baking powder
- 1/2 teaspoon salt
- Red, yellow, and green food coloring
For the Chocolate Coating:
- 1 cup semisweet chocolate chips
- 2 tablespoons vegetable oil
For Assembly:
- Parchment paper
- Non-stick spray or butter for greasing
How to Make Rainbow Cookies
1. Prepare the Pan
Begin by preheating your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, making sure to leave some overhang on the sides for easy removal. Grease the parchment paper with non-stick spray or a thin layer of butter.
2. Make the Cookie Batter
In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy. This process usually takes about 3-4 minutes with an electric mixer on medium speed.
Add the eggs, one at a time, mixing well after each addition. Incorporate the vanilla extract and almond extract.
In a separate bowl, sift together the flour, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, mixing until just combined. Be careful not to overmix, as this can lead to tough cookies.
3. Divide and Color the Batter
Divide the batter evenly into three separate bowls. Add a few drops of red food coloring to one bowl, yellow to another, and green to the third. Mix each bowl until the colors are well combined and evenly distributed. Adjust the color intensity by adding more food coloring if needed.
4. Layer the Colors
Spread the red batter evenly into the bottom of the prepared pan, smoothing it out with a spatula. Bake in the preheated oven for about 10-12 minutes, or until the layer is set but not browned.
Remove from the oven and allow the red layer to cool slightly before spreading the yellow batter on top. Smooth it out evenly. Bake the yellow layer for an additional 10-12 minutes.
Repeat the process with the green batter, spreading it over the cooled yellow layer and baking for another 10-12 minutes. Once baked, remove from the oven and let the entire pan cool completely on a wire rack.
5. Prepare the Chocolate Coating
In a small saucepan over low heat, combine the semisweet chocolate chips and vegetable oil. Stir until the chocolate is melted and smooth. Remove from heat.
6. Assemble the Cookies
Once the cookie layers are completely cool, carefully lift the entire slab from the pan using the parchment paper overhang. Place it on a cutting board.
Spread the melted chocolate evenly over the top layer of the cookies, smoothing it out with a spatula. Allow the chocolate to set before cutting.
7. Cut and Serve
Once the chocolate coating has hardened, use a sharp knife to cut the cookie slab into small squares or bars. Store the cookies in an airtight container at room temperature or in the refrigerator if you prefer them chilled.
About the Main Ingredients
Butter
Butter is essential for providing richness and flavor in the cookie layers. It should be softened to room temperature for easy mixing and to achieve the desired texture.
Almond Extract
Almond extract adds a distinct nutty flavor that complements the sweetness of the cookies. It is a key ingredient in achieving the traditional taste of rainbow cookies.
Food Coloring
Food coloring is used to create the vibrant layers that make rainbow cookies visually appealing. Gel food colors are recommended for their strength and ease of use.
Semisweet Chocolate Chips
Semisweet chocolate chips are used for the glossy chocolate coating that adds a touch of decadence to the cookies. The addition of vegetable oil helps to achieve a smooth and shiny finish.
By following these steps and tips, you’ll create a batch of rainbow cookies that are as delightful to look at as they are to eat. Enjoy these colorful treats with family and friends, and celebrate the joy of baking!
