Rhubarb Batter Cake Recipe:

Let me try to explain this delicious dessert. I’m not sure I can do it justice.  Imagine a rhubarb cake or even a rhubarb crunch without the oats.

The bottom layer is where the rhubarb lives.  It’s cooked until soft and delightful.

Over top of the rhubarb layer is a sweet vanilla cake that is perfectly light in texture.

And then the “icing” on the cake is a crunchy sugar topping.

The combination of the three layers is a match made in heaven.

Our Favorite Batter Cake Recipes

I am officially batter cake crazy. This style of cake is a perfect match for your favorite fruits.

Cherry Batter Cake

Cherry Batter Cake is so much fun to make! Fresh cherries are topped with cake batter and then sprinkled with a special sugar mixture that forms a magic crust. The result is a perfect crunchy cake topping over a light and airy cherry cake.

Peach Batter Cake

This Peach Batter Cake recipe is super easy to make with either fresh or canned peaches and has a decadent crust that will have everyone asking for seconds.

Blackberry Batter Cake

Blackberry Batter Cake is the perfect combination of a blackberry cake, blackberry cobbler and a blackberry crisp.  It has the perfect amount of sweetness to counteract the tart of the berry.  The bottom consists of a blackberry filling while the top is a simple cake with a crisp sugar topping. Topped with ice cream or plain milk (like our Dad), this recipe is a home run. 

These magic cakes are always a hit when we serve them to family and friends! They can’t get enough of the sweet fruit filling and the magic crunchy topping.

Try one or try all. You won’t be disappointed.

I suggest making these with your kids or grandkids.  The “magic” part involves pouring boiling water over top the cake before baking which kids absolutely love. You may even inspire a future food scientist.

How To Make Fresh Rhubarb Cake:

  1. Preheat oven to 375 degrees F. Spray an 8 x 8 inch baking dish with nonstick cooking spray.
  2. Mix diced rhubarb with cornstarch; arrange in the bottom of the prepared dish.
  3. Cream sugar and butter; add milk and dry ingredients alternately until the cake batter forms.
  4. Spread the cake batter so that it covers all the rhubarb up to the edge of the dish.
  5. Sprinkle with a mixture of sugar, salt and cornstarch in a thick layer over the batter.
  6. Pour boiling water over the cake until the entire top is moistened.
  7. Bake rhubarb crunch for 45-55 minutes or until golden brown.

Notes About Rhubarb Crunch without Oats:

  • Fresh rhubarb works best in this rhubarb batter cake.  Frozen rhubarb will fall apart during baking. It still tastes great, but the consistency is different.
  • This is a magic rhubarb cake because boiling water is poured over a sugar mixture right before baking.  It forms the most delicious crunchy sugar topping.
    • Add just enough boiling water so that all the sugar mixture is moistened. This takes approximately 1/2 cup.
  • For a new spin, add some ground cinnamon to the sugar topping.
