Ingredients for Rhubarb Banana Muffins
Lots of folks are scared of rhubarb because of it’s tartness – but in these muffins – they just add a little tart to your yummy brown sugar and banana muffins!
- 6 tbsp unsalted butter – you can swap with vegetable oil or coconut oil but I love the flavor from butter
- 2.5 cups diced rhubarb (thawed or fresh)
- 3/4 cup light brown sugar
- 2 cups all purpose flour
- 1½ teaspoon baking powder
- 1 teaspoon baking soda
- 1 teaspoon ground cinnamon
- ¼ teaspoon fine salt
- 2 medium sized ripe bananas
- 2 large eggs
- 1/3 cup sour cream – you can also swap with plain Greek yogurt
- 1½ teaspoon vanilla extract
- 1½ tablespoon turbinado sugar – if you’re not familiar it’s just raw coarse sugar – just adds a little crunch and sweetness

How to make Banana Rhubarb Muffins
These muffins are so easy to make – you will mess up a couple of bowls – but they’re worth it!
- Preheat oven to 375°F and spray your muffin pans with non-stick cooking spray.
- Melt your butter and set aside to cool slightly.
- Toss rhubarb in brown sugar and set aside for 10 minutes and stir twice to absorb juices. If rhubarb is frozen, thaw and drain on a paper towel prior to mixing with brown sugar.
- In a large mixing bowl, sift together your dry ingredients: flour, baking powder, baking soda, salt and cinnamon. If you don’t have a sifter, you can whisk thoroughly.
- In a separate medium bowl, at a moderate speed, beat together your wet ingredients: ripe bananas, eggs, sour cream, melted cooled butter and vanilla extract for 1-2 minutes.
- Pour egg mixture into flour mixture and fold in until just combined. Do not overmix.
- Add sugar and rhubarb mixture and fold in until combined.
- Pour batter into muffin tins about 3/4 full and sprinkle turbinado sugar over top of muffins.
- Bake for 18-25 minutes until well risen and golden. Check center with a toothpick until it comes out clean.
- – Texas sized – 25 minutes
- – Regular sized – 18 minutes
- Let muffins cool slightly in pans. Remove muffins and place on a cooling rack. Sprinkle again with turbinado sugar.
