With a blend of mixed berries and a buttery golden lid, these triple berry crumb bars taste like the best berry pie. The bars are delicious unadorned to fully savor the jammy berry filling and golden crumb topping; I also love them topped with a scoop of vanilla bean ice cream or drizzled with lemon butter glaze.

Even better than pie, these crumb bars are forgiving and flexible – use any blend of berries you love! If you’re serving a crowd for Memorial Day or 4th of July, simply double the recipe and bake in a 13 x 9-inch baking pan (and then prepare to dig in!).
