Introduction

If you’re the type who loves the sweet-tart combo in desserts, this Lemon Rhubarb Loaf is calling your name. Bursting with lemon zest and studded with juicy rhubarb chunks, this loaf is finished with a luscious lemon glaze that ties everything together in a zingy bow. Whether you’re baking for a spring brunch or want to brighten up a gray day, this easy quick bread is sunshine in sliceable form.

Why I Love This Recipe

This loaf takes the humble quick bread to new heights. It’s buttery and rich from the sour cream, tangy from the lemon, and balanced by the slightly tart rhubarb. The glaze? A citrusy kiss of sweetness that makes each bite sing. It also keeps well, freezes beautifully, and is perfect with tea, coffee, or even a scoop of vanilla ice cream.

Ingredients

1/2 cup butter, softened
1 cup sugar
2 large eggs
1/4 cup lemon juice, freshly squeezed
Zest of 1 lemon
1 1/2 cups all-purpose flour
1/2 tsp baking powder
1/2 tsp baking soda
1/4 tsp salt
1/2 cup sour cream or yogurt
1 cup diced rhubarb

For the Glaze:

1/2 cup powdered sugar
2 tbsp lemon juice
1 tbsp rhubarb syrup or compote (optional)

Ingredient Swaps & Notes

Frozen Rhubarb: Just thaw and drain before using.
Greek Yogurt: A great substitute for sour cream with a similar tang.
No Rhubarb Syrup? Skip or sub with a spoonful of strawberry or raspberry jam.
Want it Sweeter? Add 2 extra tablespoons of sugar to the batter.

Step-by-Step Directions

1. Prep & Preheat

Preheat your oven to 350°F (175°C). Grease a 9×5″ loaf pan and line it with parchment for easy removal.

2. Cream Butter & Sugar

In a large mixing bowl, cream together the butter and sugar until light and fluffy (about 3 minutes).

3. Add Eggs & Lemon

Beat in the eggs one at a time. Stir in the fresh lemon juice and zest for that vibrant citrus flavor.

4. Mix Dry Ingredients

In another bowl, whisk together the flour, baking powder, baking soda, and salt.

5. Combine Wet & Dry

Gradually mix the dry ingredients into the wet ingredients, alternating with the sour cream or yogurt until just combined.

6. Fold in Rhubarb

Gently fold in the diced rhubarb with a spatula to avoid overmixing.

7. Bake

Pour the batter into the prepared pan and smooth the top. Bake for 50–60 minutes, or until a toothpick inserted comes out clean.

8. Cool & Glaze

Cool in the pan for 10 minutes, then transfer to a wire rack. Mix glaze ingredients and drizzle over the cooled loaf. Let set before slicing.

Tips for Success

Don’t overmix – it can make the loaf dense.
Test with a toothpick around 50 minutes to avoid overbaking.
Use fresh lemons – bottled juice just won’t cut it here.

Serving Suggestions & Pairings

Serve warm or chilled with herbal tea or iced coffee.
Delicious alongside fruit-forward treats like these Caramel Apple Pie Cookies or a dollop of Brownie Batter Dip.
Add a swipe of softened cream cheese or butter for extra indulgence.

Storage & Leftovers

Room Temp: Store in an airtight container for up to 2 days.
Fridge: Keeps well for up to 5 days.
Freezer: Wrap tightly and freeze for up to 2 months (skip the glaze until after thawing).
