How to Make Rhubarb Dump Cake

Step 1: Prepare the Rhubarb

Start by washing and chopping fresh rhubarb into small, even pieces. Toss the rhubarb with sugar to let the flavors meld and soften slightly while you prepare the rest of the ingredients.

Step 2: Layer the Ingredients

Generously spread the sugared rhubarb evenly at the bottom of a greased baking dish. Next, sprinkle the dry yellow cake mix evenly over the rhubarb layer. This forms the crumbly top once baked.

Step 3: Add the Butter

Melt butter and drizzle it slowly and evenly over the cake mix. This creates a golden, crispy crust that contrasts the tender filling beneath.

Step 4: Bake to Perfection

Bake your dump cake in a preheated oven around 350°F (175°C) for 40-45 minutes, or until the edges are bubbling and the top turns a beautiful golden brown.

Step 5: Cool and Serve

Allow the Rhubarb Dump Cake to cool slightly before serving to let the filling thicken and flavors settle. It’s delightful warm or at room temperature.

Pro Tips for Making Rhubarb Dump Cake

• Even Layering: Make sure to spread the cake mix evenly over the rhubarb to avoid dry patches or soggy areas.
• Adjust Sweetness: Taste your rhubarb before baking; add more sugar if your stalks are extra tart.
• Use Fresh Rhubarb: Fresher rhubarb offers better texture and flavor than canned or frozen options.
• Butter Temperature: Melt butter just until liquid but not hot, so it spreads smoothly without cooking the cake mix prematurely.
• Watch the Bake Time: Oven temperatures may vary, so check the cake at 35 minutes to prevent over-browning.
