Hand holding rhubarb muffin

I just couldn't resist posting another rhubarb recipe! 

Springtime in Minnesota is always my favorite time of year with all the fresh rhubarb around. If you don't have a plant or two growing in your yard, chances are your neighbor does or someone else you know.

There's always a huge abundance and usually enough to pick and freeze to use at another time. I'm so excited this spring, because my aunt gave me 3 rhubarb plants to plant in my new yard. 

By next year, I will have my own to bake with! I've also planted 6 Nanking cherry bushes, 1 cherry tree and 2 apple trees! Next is the tomatoes. I am taking full advantage of having my own space to plant in after so many years of apartment living. 

Today's muffins are the perfect way to use up some of that rhubarb. These muffins have a perfect, soft texture with delicious bites of rhubarb through them. The sweet brown sugar streusel topping pairs with the rhubarb so perfectly! Another great muffin recipe we love making, are these mantecadas muffins! They get their flavor from orange zest and cinnamon! So yummy!

If you don't have buttermilk on hand, check out how to make your own in the recipe card below.

What are the ingredients in this recipe?

muffin ingredients in bowls

  • All purpose flour: It's a combination of hard and soft wheats. Bleached flour provides a softer texture. It's versatile and you can bake most anything with it!
  • Baking powder: It's a dry leavening agent, with a shelf life about 9-12 months. Baking powder is used to increase the volume and lighten the texture of baked goods by causing bubbles in a wet mixture. Baking powder is usually made with a combination of baking soda, cream of tartar and cornstarch. Once opened baking powder should be used within six months because it loses its potency and power.
  • Vanilla extract: this extract is made from vanilla bean pods soaked in water and alcohol. Try using pure vanilla extract instead of imitation. This is the most common extract used in American desserts and I put it in pretty much anything sweet, Use store bought or make your own here!
  • Cinnamon: Loaded with antioxidants and also has anti inflammatory properties it has been used medicinally around the world for thousands of years. Cinnamon is a spice from the inner bark of several tree species from the genus Cinnamomum. You can use it in sweet and savory cooking and baking.
  • Brown sugar: Often produced by adding sugarcane molasses to refined white sugar crystals. There are two varieties, light brown sugar and dark brown sugar. Dark brown sugar has more molasses, which results in a darker color, richer flavor and more moisture. Try making your own brown sugar here!
  • Baking soda: Also known as Sodium bicarbonate or bicarbonate of soda. It requires an acid and a liquid to become activated and helps baked goods rise. It can also help remove tough stains, eliminate foul odors, and clean difficult areas like the oven, microwave, and tile grout. Unopened, baking soda will remain shelf stable until the best-by date on the box, generally 2 years. Once opened baking soda should be used within six months because it loses its potency and power.
  • Butter: A dairy product consisting of approximately 80% butterfat and made from the fat and protein components of milk or cream. Most commonly made from cow's milk, but can also be made from sheep, goat, yak, or buffalo milk.
  • granulated sugar
  • large egg
  • greek yogurt
  • vegetable oil
  • buttermilk
  • rhubarb
