How to Make Rhubarb Streusel Coffee Cake

Step 1: Prepare the Streusel Topping

Combine brown sugar, all-purpose flour, cinnamon, and cold, cubed butter in a bowl. Use a pastry cutter or your fingers to blend until the mixture resembles coarse crumbs. This crumbly topping is key to adding sweet, crunchy texture that contrasts with the soft cake.

Step 2: Mix the Cake Batter

In a large bowl, cream softened butter and granulated sugar until light and fluffy. Beat in eggs one at a time followed by vanilla extract. In a separate bowl, whisk together flour, baking powder, baking soda, and salt. Gradually blend the dry ingredients into the wet mixture, alternating with milk or buttermilk to keep the batter moist and tender.

Step 3: Fold in the Rhubarb

Gently fold the chopped rhubarb into the batter, ensuring even distribution without overmixing, which could make the cake tough. The rhubarb pieces add bursts of tartness that shine through the sweet cake base.

Step 4: Assemble the Cake

Pour half of the batter into a greased or parchment-lined baking pan. Sprinkle half of the streusel evenly over the surface, then add the remaining batter and top with the leftover streusel. This layered approach results in crunchy topping both within and on top of the cake.

Step 5: Bake Until Golden and Set

Bake in a preheated oven (usually at 350°F / 175°C) for about 45-50 minutes, or until a toothpick inserted into the center comes out clean and the streusel topping is golden brown. Let the cake cool slightly before slicing to maintain its shape and texture.

Pro Tips for Making Rhubarb Streusel Coffee Cake

• Use fresh rhubarb: Freshly picked rhubarb offers the best flavor and texture for this coffee cake.
• Chill the butter: Cold butter in the streusel helps create that perfect crumbly topping texture.
• Don’t overmix: Combine ingredients just until incorporated to keep the cake light and tender.
• Line your pan: Use parchment paper for easy removal and clean slicing after baking.
• Cool completely: Allow the coffee cake to cool before serving to enhance flavor development and make cutting easier.
