This delicious coffee cake is a perfect way to start your day, whether it's for a morning meal, brunch, or even as a dessert! With a unique twist on the classic coffee cake, this recipe incorporates rhubarb, adding a delightful tartness to the sweet cake. The combination of Betty Crocker's Super Moist yellow cake mix and cream cheese creates a moist and fluffy base, while the rhubarb adds a refreshing burst of flavor. The cake is then topped with a crumbly mixture of flour, sugar, and butter, giving it a delightful crunch and extra sweetness. Baking it at a lower temperature ensures a perfectly cooked cake, and the toothpick test is a great way to ensure it's done to your liking. With a prep time of around 2 hours and 40 minutes, this cake is definitely worth the wait and will impress your taste buds. Whether you serve it warm or let it cool completely, this rhubarb coffee cake is a delightful treat that will brighten up your day. Enjoy the process of baking and the wonderful flavors that come together in this mouthwatering coffee cake!
