Rhubarb Cake With Coconut Pecan Topping Recipe
Here is a rhubarb cake with coconut pecan topping for that person with a huge sweet tooth! The cake is dense, moist, and rich. Spread the boiled topping made of brown sugar, butter, coconut, and chopped pecans over the still-warm cake, so all that buttery richness soaks in.
I was immediately intrigued when I saw a picture of this cake. The recipe stood out as a unique twist on a rhubarb dessert! Of course, I had to try it myself, and I have never tasted a rhubarb cake so crunchy and sweet. It is amazing.
A Moist And Tender Vanilla Cake Starts With Two Secret Ingredients
The “secret” ingredients aren’t a secret at all! They are buttermilk and vegetable oil. They are the dynamic duo when you want a moist, tender cake with a very fine crumb!
Buttermilk is acidic. It breaks down the gluten in the flour and tenderizes the cake crumb. Buttermilk also adds moisture and has a pleasantly tangy flavor that plays well with vanilla.
Oil makes cakes that stay moist longer than butter cakes because it remains a liquid at room temperature. The water in the butter evaporates, and cakes made with it can dry out more quickly.
All the rise in a cake made with these ingredients comes from loads and loads of teeny air bubbles created when acidic buttermilk meets alkaline baking soda. The crumb is very even, without any big air holes and a melt-in-your-mouth texture.
Put These Two Things On The Rhubarb Before You Start The Cake
Put one-half cup of sugar and a tablespoon of flour on the finely diced rhubarb and stir, then set it aside while making the cake. Thie sugar will start to draw the juices out of the rhubarb, and the flour will help keep it suspended in the batter while the cake bakes. This way, all the rhubarb won’t sink to the bottom.
Combine the sugar, oil, vanilla, baking soda, and egg, and beat the mixture until it’s creamy. Then add buttermilk and flour alternately and beat until well blended, scraping down the sides of the bowl a time or two.
Finally, fold the rhubarb into the batter, and put the mixture into the greased baking dish. Bake in a 350-degree oven for about thirty-five minutes but do not underbake. A toothpick inserted in the center of the cake should come out clean, and the cake should start pulling away from the sides of the pan.
If you underbake the cake, it can sink in the center. 😢 I may have learned this from experience. Don’t make the same mistake! LOL

Make The Yummy Four Ingredient Topping While The Cake Bakes
How can you go wrong with a mixture of coconut, pecans, butter, and brown sugar? There is no way.
Make the incredible topping when the cake is baking. In a heavy saucepan, combine the ingredients and bring them to a boil for three minutes, stirring constantly. Set aside while the cake finishes baking. Keep the topping warm by putting the lid on the pan.
When you take the cake out of the oven, let it sit on a cooling rack for a few minutes. Then, while the cake is still warm, spread that coconutty goodness carefully on top of the still-warm cake, coaxing it to the edges. It is as sweet and tasty as it looks!
This cake uses rhubarb, but rhubarb is not the star of the show in this rhubarb cake with coconut pecan topping recipe. The topping is what this cake is all about.
