    1. Preheat the oven to 350 degrees.

    4. Once the eggs are fluffy, slowly add 1/2 of the sugar while continuing to mix. Next, add the vanilla and finish by slowly adding the rest of the sugar.
    5. Continue to beat until the egg whites are shiny and firm. Tranfer to a big plastic bag.
    6. Using your finger, add a little of the batter to the corners of 2 cookie sheets. Place parchment paper to the cookie sheet and make sure they stick to the batter and secure the parchment paper to the cookie sheet.
    7. Cut a small corner off of the plastic bag and pipe the meringues into 2-inch wide mounds on the cookie sheet. Leave room in between the cookies.

    2. Once the cookies are ready, place in the oven, turn off the heat and let cook in the oven for 2 hours. DO NOT open the oven!
    3. While the cookies are cooking, cube up your watermelon and purree it in a blender.

    5. Add the 1/3 cup of sugar and lime juice to the watermelon juice and bring to boil.

watermelon-filled meringue cookie tips and tricks

  • These cookies are delicious on their own so feel free to skip the whole watermelon filling if it seems like a little too much. The watermelon filling though is the perfect cool bite, especially during the summer time when the watermelon are perfect!
    I used a tiny disposable pipette which you can find at specialty candy, cake, or kitchen equipment shops. If you don’t have one you can always gently use a turkey baster or even a baby spoon to slowly spoon it in.
    True lime is a powdered lime juice that is great for cooking. You can find it in the baking aisle of the grocery store, or if you want you can use realy lime zest instead.
