Simple Rhubarb Muffin Recipe

Ever since I first tried these Rhubarb Muffins, I became instantly obsessed! This is a recipe that my Mom has apparently been holding back on us for decades. For my sister’s bridal shower a few years ago, she made these rhubarb muffins and everyone was in love and asking for the recipe.

She claims that she has made them a few times in the distant past, but just forgot about these in the back of her pile of recipes. She typically makes this Rhubarb Custard Pie a few times each rhubarb season, which we all love as well, but these rhubarb muffins are a definite contender for using up all the rhubarb from our patch.

Grandma’s Rhubarb Muffins

We asked her where she found the recipe and she replied that she has had it forever and it is a recipe from my grandma. What the heck? Why in the world hasn’t she been making these muffins every single summer as soon as the rhubarb is ripe? Needless to say, we have made them many times since she re-introduced this recipe.

The best part about these rhubarb muffins is that you can not only enjoy them as a treat but seeing they are a muffin, it’s a great excuse to have a sweet breakfast!

For my sister’s morning bridal shower, we popped some of these DIY Pinwheels in each one to dress them up and they were a huge hit with everyone. It dressed up this simple rhubarb recipe with a fun homemade twist.

How to make rhubarb muffins

Time needed: 50 minutes

To make these easy rhubarb muffins, preheat your oven to 325F, gather your ingredients and equipment and they will be ready to bake in just 20 minutes!

Mix Wet Ingredients In a large mixing bowl, combine the brown sugar, oil, egg, buttermilk and vanilla extract. Mix well.

Sift Dry Ingredients Add the flour, salt and baking soda to a sifter and sift over the wet ingredients. Mix just until combined, being sure not to overmix.

Add Rhubarb & Walnuts Add rhubarb and 1/2 cup chopped walnuts to the batter and fold just until the nuts and rhubarb are incorporated into the batter. Divide the batter between 12 lined muffin tins.

Top with Streusel In a small bowl, combine 1/4 cup brown sugar, 1/2 teaspoon cinnamon and 1/4 cup chopped walnuts. Sprinkle one tablespoons of streusel over each muffin.

Bake Bake the streusel topped rhubarb muffins at 325F for 30 minutes. Insert a toothpick into the center of the muffins to check whether they are done. If the toothpick comes out clean, they are done. If it comes out with batter, add an additional few minutes to the baking time.
