Simple Ingredients

If you’ve read or tried any of my other recipes, you know that I’m a fan of simple, everyday ingredients. This bread definitely follows that pattern. Nothing too fancy and as always there are some options.


Buttermilk definitely gives this bread flavor and moistness. Real buttermilk will provide the best of all worlds but if you don’t have any on hand and don’t want to run to the store, you have options.

The powdered buttermilk sold in the baking aisle of the grocery store will work.

The soured milk trick – 1 cup of regular milk combined with 1 Tablespoon of vinegar or lemon juice and allowed to sit for a few minutes – works as a buttermilk substitute. It’s not exactly the same but close enough.

Fresh Rhubarb

Rhubarb season tends to last a while, giving us ample opportunity to make multiple loaves of this great recipe.

If it’s too hot to bake or you’ve had your fill of rhubarb recipes at the moment. Chop the rhubarb and freeze into pre-measured portions. Then you can thaw and bake this bread up later in the year.

For this recipe, I did dice the rhubarb into small pieces, rather than just slice the stalks. Slices would likely work but be less distributed.


Admittedly this is a very dairy heavy recipe. Vegetable oil could be substituted for the melted butter, if desired.

If you use unsalted butter add 1/2 teaspoon of salt to the dry ingredients.

Sour Cream

I used full-fat sour cream in the recipes I tested. I imagine a low-fat would work.

Though, I didn’t test it specifically, generally speaking, a plain Greek yogurt works as a substitute for sour cream in most recipes.

Optional Additions

Want to switch up your bread a bit? Consider these options:

Add the streusel topping from my rhubarb muffins to the top of the bread before baking.

Stir in up to 1 cup of chocolate chips to the bread.

Drizzle the baked and cooled loaf of bread with a vanilla glaze or melted chocolate.

Fold in up to 1 cup of chopped nuts with the rhubarb for some hearty crunch.

Switch out half the rhubarb for chopped sweet strawberries for the always favorite strawberry rhubarb combination.

How to Serve

While we call this a tasty quick bread, it’s definitely on the line of a rhubarb loaf cake and should be treated as a sweet treat.

Because it is sweet, it goes well at a brunch in combination with savory choices like eggs and bacon.

It’s a great afternoon snack with tea or coffee.

Definitely tuck into lunch boxes for a little mid-afternoon treat.

Make it dessert by dusting slices with powdered sugar or serving with a scoop of ice cream.

Bake it in a mini loaf pan instead and share with neighbors and friends – adjust the baking time as necessary.

How to Store

This bread will keep fresh if stored in airtight container at room temperature for about 4 days.

It freezes incredibly well, if you’re inclined to make a double batch.

Simply put baked and cooled loaves into freezer bags or wrap tightly in plastic wrap and freeze.

Thaw frozen bread at room temperature prior to serving.

Use up frozen bread within 6 months for best flavor and to prevent freezer burn.
