This coffee cake is perfect for a lazy weekend brunch. The strawberries and rhubarb add a burst of flavor, and the cake is moist and tender. The crumb topping is made with butter, flour, and sugar, and is deliciously crunchy. Using a food processor to mix the batter and crumb topping makes it quick and easy to prepare. Serve it with a cup of coffee or tea for a delicious breakfast or dessert.
