• If you grow rhubarb, you can bake and freeze this bread to enjoy all summer long.
• Quick breads are so much simpler than pies and just as tasty!

Ingredients and Pantry Notes

• Sugar
• Ground Cinnamon
• Flour
• Salt
• Vegetable Oil (I like Canola oil for baking)
• Baking Powder
• Large egg (room temperature)
• Milk (room temperature)
• Rhubarb, washed, trimmed, and chopped (fresh preferred; frozen OK)
• Cinnamon sugar (for topping)

Mix, Swirl, and Bake

1. Grease the loaf pan, dust with flour or spray with oil-and-flour nonstick spray; place a small strip of parchment on the bottom and grease the top of the paper.
2. Set the egg and milk out to warm to room temperature (about 1 hour) or warm the egg in warm (not hot) water to take the chill off.
3. Wash, trim, and chop the rhubarb; set aside.

4. Mix together the cinnamon-sugar topping and set aside.

   
5. Whisk the dry ingredients together in a large bowl until well combined.
6. Whisk the wet ingredients together in a separate bowl.
7. Pour the wet ingredients into the dry and stir gently just until combined, keeping the batter lumpy and avoiding overmixing.

8. Fold the chopped rhubarb into the batter.

   

9. Spread half the batter into the prepared pan.
10. Sprinkle half the cinnamon-sugar over the batter, add the remaining batter, then top with the remaining cinnamon-sugar.
11. Bake until a toothpick inserted in the center comes out clean.

12. Cool the loaf in the pan for 10–15 minutes, then carefully lift it out onto a wire rack to finish cooling.

    

Baker’s Tips and Shortcuts

• This bread tastes best with fresh, in-season rhubarb, but frozen works fine—just add it straight from the freezer.
• PRO Tip: Check your baking powder’s expiration—most folks overlook it since it’s used less often than baking soda. To test your baking powder, drop a spoonful into hot water. If it bubbles up, you’re good. If not, grab a fresh can to get the perfect rise.
• Always test for doneness with a toothpick in several spots near the top. If it comes out with wet batter, give it more time in the oven.
• PRO Tip: Cool your bread on a rack for about 10 minutes before removing it from the pan. Pull it out too soon, it may fall apart; wait too long, and it might stick.
• Some of that delicious cinnamon sugar topping might not stick when you flip it out. PRO Tip: Instead of sprinkling, try swirling the cinnamon sugar into the batter with a knife or thin spatula before baking.
• From a reader: When lining your pan, have the parchment paper extend past the edges to make a “handle” for lifting the loaf out cleanly. No mess and your cinnamon sugar stays right where you want it!

Rhubarb is technically a vegetable but feels like a fruit in recipes because we pile on sugar to balance its tartness. This makes it perfect in pies, crisps, tarts, and yes, quick breads like this one.

I started with my mom’s old rhubarb bread recipe on a worn index card. My first experiment was topped with streusel, but that mostly fell away as I sliced. The next try mixed a few recipes but lacked punch. Finally, adding cinnamon made all the difference—bringing the flavor to life.

Flavor Swaps and Mix-Ins

Ready to switch things up? Here are some great swaps and add-ins to try that still play nicely with the cinnamon and rhubarb base.

• Fruit changes: Swap some or all of the rhubarb for strawberries, raspberries, or chopped apples—strawberry-rhubarb is a classic combo you can’t go wrong with.
• Frozen rhubarb: Add it frozen but expect to bake a bit longer.
• Add texture: Fold in ½ to ¾ cup chopped walnuts or pecans, or mix in ½ cup raisins or dried cranberries for extra flavor and chew.
• Change up fats/liquids: Use melted butter instead of vegetable oil for a richer crumb, or try using half-and-half instead of milk to make it extra tender.
• Toppings: Instead of sprinkling cinnamon sugar on top, stir it into the batter, add a streusel, or drizzle a simple powdered sugar glaze after cooling.
• Spices and zest: Add ½ teaspoon ground ginger or cardamom, or 1–2 teaspoons lemon or orange zest to brighten the flavors.
• Different shapes: This batter works great for muffins (bake about 18–22 minutes) or mini loaves—just reduce baking time and check doneness with a toothpick.

Storing, Freezing, and Reheating

Wondering how to keep this bread fresh or make it ahead? Here’s the scoop.

• Room temperature: Once the bread is fully cooled, wrap it tightly in plastic wrap or tuck into an airtight container. It will keep well for 1–2 days.
• Refrigerate: For best flavor and easier slicing, wrap the loaf well and refrigerate it; it should stay good for about 3–4 days.
• Freeze: Wrap the cooled bread in plastic wrap, then foil or pop it in a freezer-safe bag. You can also freeze individual slices separated by parchment paper. Frozen bread lasts up to 3 months.
• Thawing and reheating: Thaw slices overnight in the fridge or for a couple of hours at room temp. Warm slices in the microwave for 15–30 seconds or in a toaster oven at 325°F for 5–8 minutes. For warming a whole loaf, tent it with foil and heat for 10–15 minutes at 300–325°F.
• Make-ahead tips: For the best rise, bake the batter the same day you mix it. If you must prep early, combine the dry ingredients in advance or bake the loaf ahead and store the finished bread instead of the raw batter—baking powder and soda lose their punch over time.

Rhubarb and Baking FAQs

What does rhubarb taste like?

Rhubarb is very tart and a vegetable technically, but since it’s almost always cooked with lots of sugar, it tastes more like a tangy fruit. It pairs wonderfully with sweet fruits like strawberries, bananas, and apples.

Are rhubarb leaves poisonous?

Yes, rhubarb leaves contain high levels of oxalic acid, which can be dangerous and cause kidney failure if eaten in large amounts. Always discard the leaves and use only the stalks.

When is rhubarb season?

Rhubarb is freshest in spring and early summer. As the season moves on, the stalks get tough and less tasty, so try to bake while the stalks are young and tender.

How do you store rhubarb bread?

Keep rhubarb bread wrapped well at room temperature for a day or two. Then wrap it and refrigerate for up to four days. For longer storage, slice and freeze it.

Can you freeze rhubarb bread?

Absolutely! Quick breads freeze really well. Wrap tightly in plastic wrap and then a freezer bag. It stays fresh up to three months in the freezer.

How else can rhubarb be eaten?

Apart from bread and muffins, rhubarb is divine in pies, coffee cakes, crisps, sauces, and more. You can generally swap fruit for rhubarb in most recipes, but just remember to adjust the sugar levels accordingly.

Quick bread means no yeast here! Instead, baking powder or baking soda helps it rise fast with no waiting or proofing. Classic quick breads are banana bread, pumpkin bread, muffins, biscuits, and scones—perfect for quick weeknight baking that delivers big flavor without fuss.
