Fluffy Rhubarb breakfast muffins, a deliciously easy recipe, these slightly sweet muffins are loaded with rhubarb, soft & fluffy, with added texture from oats. Serve warm for breakfast or brunch, or add to a lunchbox.

I love muffins and these oatmeal muffins are my new favorite way of eating breakfast. They're so convenient, you can eat them on the go, or pack a few and take them to work, or pop in a lunch box.
The oatmeal in these adds a nice texture and gives the muffins a bit of body and makes them filling. Whilst not chewy, they are fluffy and light.
The addition of rhubarb makes for a slightly tangy sharpness against the sugar.

These muffins aren't particularly sweet, there is just a hint of sugar taste. So if you do have a sweet tooth, feel free to add a bit more sugar or a drizzle of honey in the batter.

We've answered a few common questions below about muffins, and how you can make sure you get perfectly baked, light and fluffy muffins each time.
The recipe is very easy, and the ingredients are regular, store cupboard ingredients.
We've used fresh rhubarb, which I froze in batches. Keep the rhubarb frozen until you want to use them. Canned rhubarb will also work. Make sure you drain any excess liquid so the batter isn't extra 'wet'.

I tend to have a lot of rhubarb in my freezer. Lucky for me I have 2 neighbors who grow rhubarb and they will regularly keep me topped up with fresh rhubarb so I just wash, cut into pieces, and bag it, then freeze. We've got a great fluffy rhubarb pancake recipe which is ideal for a weekend breakfast! Plus many more easy rhubarb recipes, so be sure to check those out too!
We've got a variety of muffins you can make, and if you'd like to make some different flavored muffins using a variety of fruits, we have recipes for those too so be sure to check those out!
Can I use fresh or frozen rhubarb?
You can use either, and also canned rhubarb. Just be sure to drain and pat dry on kitchen paper to remove any excess liquid.

How can I make my muffins soft and fluffy?
- Make sure your ingredients are at room temperature. This will help you get a smooth batter.
- Adding the right amount of baking powder will also make a difference, so be sure to check quantities when you look at muffin recipes!
- Don't over-mix your muffin batter. Make sure you mix just enough to combine. It's ok if there are spots of flour not mixed thoroughly. This is good and will help your muffins be super fluffy and rise well.
How do you make moist and tender muffins?
Adding some acid, such as lemon juice or buttermilk will give you moist, soft, and tender muffins.
Why are my muffins soggy inside?
This can happen if you leave muffins to cool in their pans for too long. Make sure you allow them to cool for 5 minutes in the pan and then transfer them to a cooling rack to allow the cooler outside air to circulate around them.
Another reason is if you haven't baked them for long enough or at a too low temperature.
What can I use if I don't have muffin cases to hand?
You'll see 2 different sets of photos here, some are using shop-bought muffin cases, and the other photos show homemade muffin cases, which are simply pieces of parchment paper cut into squares. So if you run out of muffin cases, you can always make your own, it doesn't take long to cut up 12 squares of parchment paper.

½ teaspoon salt
1 tablespoon baking powder
½ cup or 45g rolled oats, old-fashioned or quick-cooking

2. Roughly chop the rhubarb into 1 inch pieces, leaving them chunky.

3. In a bowl, add the milk and lemon juice, stir and then add the oatmeal.

Then add the remainder of the wet ingredients and using a fork, beat so the eggs are well combined with the rest of the wet ingredients. Set aside.

5. In a separate large bowl, measure out the remaining dry ingredients and combine with a spoon so everything is mixed in well.
