Follow this straightforward guide to create your Easy Jello Meringue Cookies:

1. Preheat the Oven: Start by preheating your oven to 200°F (93°C). Line a baking sheet with parchment paper.

2. Prepare Egg Whites: In a clean, dry bowl, add the egg whites and cream of tartar. Beat the mixture with an electric mixer on medium speed until soft peaks form.

3. Add Sugar Gradually: While continuing to beat, gradually add the granulated sugar, one tablespoon at a time. Continue whipping until stiff peaks form and the mixture is glossy.

4. Incorporate Jello: Gently fold in the Jello powder and vanilla extract until evenly mixed. Be careful not to deflate the meringue.

5. Pipe the Cookies: Using a piping bag, pipe the meringue onto the prepared baking sheet in small dollops, about 1 inch apart.

6. Bake: Place the baking sheet in the preheated oven. Bake for 1 hour or until the cookies are dry to the touch and can be easily lifted from the parchment.

7. Cool: Turn off the oven and let the cookies cool inside with the door slightly ajar for about 30 minutes.

These simple steps will lead you to create delightful meringue cookies that boast fun flavors and colors!
