Delicious Rhubarb Dessert Recipe

Nothing says summer better than a delicious dessert. Sometimes when it is warm out, a piece of dessert becomes your meal. This dessert most certainly is at least a filling and scrumptious snack.

Summer Cake Recipe for Those Busy Days

This cake goes together quickly. Just prep the rhubarb, mix the dry ingredients and the wet ingredients separately.

Add some of the dry ingredient mixture to the diced rhubarb as this will keep the rhubarb from all ending up on the bottom of the cake.

Mix everything together and bake.

Make the rich, creamy, and buttery sauce and you are all set for a delicious taste experience. The cake is extremely moist with a tangy taste of rhubarb in every bite.

Making the Buttery Cream Sauce

The addition of the vanilla buttery cream sauce just takes this cake to the next level.

Just melt butter in a saucepan, add the sugar, cream, and vanilla. Heat until it comes to a boil, stirring constantly. Let it boil a minute and turn off the burner.

Awfully hard not to have more than one piece.

Variations to this Dessert Cake Recipe

Turn this cake into a poke cake. Once the cake is done, use a skewer or something maybe a bit blunter like a chop stick and poke holes in the top of the cake. Then just drizzle on the vanilla sauce.

Make an eggless cake. You can leave out the eggs in this recipe. It will still work. Just know that if you overbake it, it will be dry. The eggs help keep this cake moist.

Swap out the fruit. This is just a perfect recipe to use just about any kind of fruit with. Dark sweet cherries, strawberries, peaches, pears, or mango would work especially well with this recipe.

Add a different flavoring extract in the vanilla sauce. We added vanilla extract to our sauce; however, other flavorings would work well too. Try a bit of rum, lemon, orange, or strawberry extract.

Can you Make this with Frozen Rhubarb?

Yes, you can. Thaw and drain the liquid from the rhubarb before adding it to the recipe.

Can you Freeze this Cake?

Yes, bake the cake and wrap it well in plastic wrap. It will freeze nicely up to 3 months. Thaw the cake before serving and while that is thawing, make the vanilla sauce.

How Long with This Rhubarb Cake Last?

That is a loaded question. It does not last past 3 days even with our small family. However, we do cover the cake and refrigerate it and it should last up to 5 days. The vanilla sauce we have in a separate airtight container in the refrigerator. That has the same shelf life. We just warm it up before serving.

If you love rhubarb desserts, I urge you to give this Rhubarb Pie a try. Just dice the rhubarb, blend the other ingredients, and bake. Just delicious and so easy too.

Ingredients

Rhubarb Cake Ingredients

  • 4 Cups Rhubarb Diced
  • 4 Cups All-Purpose Flour
  • 2 Cups Granulated Sugar
  • 4 Teaspoons Baking Powder
  • ½ Teaspoon Salt
  • 2 Cups Milk
  • 6 Tablespoons Butter Melted

Instructions

Rhubarb Cake Instructions

  • Clean and dice the rhubarb. Place that in a bowl and set aside.
    How to Make Rhubarb Dessert
  • Melt the butter in a microwave-safe container. I generally set the timer for 25 seconds, check the butter and see if it needs another 25 seconds. Once melted, set aside to cool a bit.
  • In a large bowl, add the dry ingredients; flour, sugar, baking powder, and salt. Give this a mix.
  • Then take about a cup of the dry mixture and add it to the rhubarb. Mix that. This makes sure that the rhubarb will stay incorporated throughout the cake and not end up in a lump on the bottom.
  • Next mix the wet ingredients, milk, butter, and eggs.
  • Add the wet ingredients to the dry ingredients and mix with a whisk or spoon to incorporate. When this mixture is just blended well, add the rhubarb mixture, and fold that in.
  • Pour batter into a pan that has been sprayed with oil or brushed with melted butter. Bake for 40 minutes. The top of the cake should spring back when lightly touches.

Buttery Vanilla Sauce Instructions

  • Melt butter in a saucepan, add the sugar, cream, and vanilla. Heat until it comes to a boil, stirring constantly. Let it boil a minute and turn off the burner.

  • Let cool a bit before serving on top of the cake.
  • To serve the cake, I cut 15 slices in the 9 X 13 cake pan. This is a generous amount of cake. Pour a bit of the buttery vanilla sauce on top and enjoy.
