To make the perfect Crackle-Topped Rhubarb Coffee Cake, gather rhubarb, cake mix, sugar, eggs, sour cream, and cinnamon.
Start by mixing the cake mix, sugar, eggs, and sour cream to create a moist and flavorful cake batter.
Gently fold in the chopped rhubarb, adding a tart and tangy contrast to the sweet cake.
Prepare a crumbly topping with a mixture of cake mix, sugar, and cinnamon.
Sprinkle the crumbly topping over the rhubarb cake batter, creating a delightful crackle effect.
Bake until the cake is golden brown and a toothpick comes out clean when inserted.
Enjoy your Crackle-Topped Rhubarb Coffee Cake – a perfect blend of sweet, tart, and crunchy in every bite!
