Directions
1. Prepare the loaf:
-
Preheat your oven to 350°F (175°C). Grease and flour a 9×5-inch loaf pan or line it with parchment paper.
-
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
-
In a large bowl, beat the softened butter and granulated sugar together until light and fluffy (about 3-4 minutes).
-
Add the eggs, one at a time, beating well after each addition. Stir in the vanilla extract, lemon juice, and lemon zest.
-
Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk. Start and end with the dry ingredients, mixing just until combined. Be careful not to overmix.
-
Toss the chopped rhubarb with 1 tablespoon of flour to prevent it from sinking to the bottom of the loaf. Gently fold the flour-coated rhubarb into the batter.
-
Pour the batter into the prepared loaf pan and smooth the top.
-
Bake for 55-65 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs. If the top begins to brown too quickly, tent the loaf with aluminum foil and continue baking.
-
Remove from the oven and allow the loaf to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
2. Make the glaze:
-
In a small bowl, whisk together the powdered sugar and fresh lemon juice until smooth.
-
Once the loaf is completely cooled, drizzle the glaze over the top, allowing it to drip down the sides.

FAQs
1. Can I use frozen rhubarb for this recipe?
Yes, you can use frozen rhubarb. Just make sure to thaw and drain it well before adding it to the batter to prevent excess moisture.
2. Can I make this loaf without buttermilk?
If you don’t have buttermilk, you can use regular milk with a tablespoon of lemon juice or vinegar to create a buttermilk substitute. Let it sit for 5 minutes before using.
3. Can I skip the glaze?
Yes, the glaze is optional. If you prefer a less sweet loaf, you can skip it, and the loaf will still be delicious. You can also dust it with powdered sugar instead for a simpler finish.
4. Can I add other fruits to the loaf?
Yes, you can experiment with other fruits like strawberries, blueberries, or blackberries. Make sure to adjust the amount of fruit based on how much liquid it will add to the batter.
5. How do I prevent the rhubarb from sinking to the bottom?
Tossing the rhubarb in a tablespoon of flour before adding it to the batter helps to keep the fruit suspended evenly throughout the loaf.

8. How do I make this loaf more moist?
The loaf is naturally moist due to the buttermilk and rhubarb. However, if you’d like it to be even more moist, try adding a couple of tablespoons of yogurt to the batter.
