This rhubarb cream pie was adapted from my grandmother’s recipe. This was my dad’s favorite pie growing up, and my grandmother used to make two at a time because he loved it so much. This classic, old-fashioned pie features tart and tangy rhubarb with a sweet and creamy custard filling encased in a buttery, flaky pie crust for an easy, decadent dessert. This delicious and beautiful pie has the right balance of flavors and is absolute spring and summer dessert perfection.
