Jello Meringue Cookies offer a delightful sensory experience with their crisp exterior, melt in your mouth texture, and vibrant fruit flavors. These light and airy treats transform simple egg whites into clouds of sweetness that crackle pleasantly between your teeth while dissolving almost instantly on your tongue. The addition of Jello powder brings both brilliant color and concentrated fruit flavor that appeals to both children and adults.
I first made these cookies with my niece during a rainy weekend, and we were both amazed at how something so simple could transform into such magical little morsels. The look of wonder on her face as the egg whites expanded into glossy peaks remains one of my favorite baking memories.
Ingredient Breakdown
- Egg whites: form the structural foundation of meringues and must be completely free of yolk
- White vinegar: stabilizes the egg whites and helps maintain their volume while baking
- Cornstarch: absorbs excess moisture ensuring a crisp rather than chewy finished texture
- Granulated sugar: provides sweetness while also creating structure when properly incorporated
- Jello powder: delivers concentrated flavor and vibrant color that transforms plain meringues into exciting treats
Preparation Steps
- Initial Meringue Formation:
- Preheat oven to 200°F. Beat room temperature egg whites until foamy, add vinegar and cornstarch, and continue beating until soft peaks form.
- Sugar Incorporation:
- Add sugar gradually, one tablespoon at a time, beating until glossy stiff peaks form.
- Flavor Addition:
- Add Jello powder to meringue and beat briefly until fully combined and vibrantly colored.
- Forming And Baking:
- Pipe or spoon meringue onto parchment-lined baking sheets, bake for 90 minutes, then leave cookies in the oven overnight or at least 4 hours with the door closed to fully dry.

My absolute favorite combination has become raspberry and lime Jello mixed into separate batches then piped in alternating colors onto the baking sheet. My family requests these for nearly every gathering now, especially during summer when their bright flavors seem particularly refreshing alongside fresh berries and lemonade.
Festive Occasions
These colorful meringues make perfect additions to holiday cookie platters where they can be customized to match seasonal themes. Create red and green versions for Christmas, pastel colors for Easter, or orange and black for Halloween celebrations. Their lightweight nature makes them ideal for packaging as party favors for birthdays or baby showers, and children are always delighted by their candy like appearance and sweet fruity taste.
Cookie Variations
Experiment with different presentation styles by adding food grade edible glitter before baking for sparkly special occasion cookies. Create sandwich cookies by adding a thin layer of white chocolate between two fully dried meringues for an elegant dessert option. Crush completely cooled meringues and fold into softened ice cream for a fruity cookies and cream variation that delivers both flavor and texture in each spoonful.
Preservation Techniques
Store completely cooled meringue cookies in airtight containers with tight fitting lids to prevent humidity from softening their crisp texture. Place paper towels in containers to absorb excess moisture in humid climates. Properly stored meringues remain fresh for up to two weeks at room temperature. Avoid refrigeration to prevent condensation softening the cookies.

These jello meringue cookies have become my signature contribution to family gatherings and school bake sales. Their bright colors and fruity flavors seem to make everyone smile, making them a joy to bake again and again.
Frequently Asked Questions
- → Why do I need to process the sugar for meringues?
- Processing granulated sugar in a blender creates finer sugar crystals that dissolve more easily into the egg whites. This helps create a stable meringue with a smooth texture instead of a grainy one, and prevents weeping or deflating.
- → Can I use egg whites from a carton for these meringues?
- Fresh egg whites work best for meringues. Carton egg whites often contain preservatives that can prevent them from whipping to stiff peaks. If using carton egg whites, look for ones specifically labeled as suitable for whipping.
- → Why are my meringues sticky after baking?
- Sticky meringues usually indicate they need more drying time. Humidity can also affect meringues, so try to make them on a dry day. If they're sticky after cooling, you can return them to a 200°F oven for another 15-30 minutes to dry them out further.
- → What jello flavors work best for these meringues?
- Any flavor works well! Popular choices include strawberry, raspberry, lime, orange, and berry blue. You can also experiment with less common flavors like watermelon or pineapple for unique treats. Avoid sugar-free jello as it won't provide the same results.
- → How long do these meringue cookies stay fresh?
- When stored in an airtight container in a cool, dry place, these meringue cookies can last up to 2 weeks. Avoid storing them in the refrigerator as moisture will make them soft and sticky.
