Strawberries and blueberries come together with a cookie tart to form the perfect Fourth of July dessert! This totally works for other holidays as well, so there’s no excuse NOT to make it!
In a stand mixer, combine the butter and sugar and mix until light and fluffy. Scrape the sides of the mixing bowl to ensure everything is combined evenly.
Add the vanilla and egg. Mix until incorporated.
Add the remaining dry ingredients and mix until just combined.
Press into an 8×11 tart pan or 9×9 baking pan. Bake until the edges are set and the center has puffed and fallen, 20-25 minutes.
Remove from oven and cool. The crust can be made a day in advance or up to one week ahead and frozen.
For the filling
Mix all ingredients together and stir until smooth. Taste and adjust sweetness if desired.
Spread evenly on prepared and cooled crust.
Place strawberries in rows on the top, leaving a corner for the blueberries.
Repeat step with rows of blueberries in the open corner.
Mix together jelly and water and brush on top of the fruit.
