Sourdough Discard Blueberry Lemon Muffins
These Sourdough Discard Blueberry Lemon Muffins have just the right blueberry to lemon ratio and are topped with an easy sugary crumble topping that gives it an added touch of sweetness.

Right now I am loving anything with a blueberry – lemon combination… which is funny, because growing up I hated blueberries – and lemons, for that matter. Funny how things change.
After visiting the blueberry patch (something I now like to do annually while in season) I am on the lookout for various ways to use up our pickings.
They are so pretty on my wooden cake plate in our kitchen and don’t stay there long.
Just a tip that works in my house… if you want something eaten and not gone to waste, put it out for a quick grab. If it’s in plain view, it gets eaten every time. As with anything made from scratch, it will only last so long without all those pesky preservatives, so make sure everyone in your house knows what’s ready to eat. Made a lot of something? Most things freeze well – as do these Sourdough Discard Blueberry Lemon Muffins.
Are you on the sourdough train??

Let me be honest here – sourdough is still a sour subject for me.
I have done several starters – my very first one being the best, until it ended up all over the kitchen floor one Saturday afternoon several years ago. I can still see all the pretty bubbles… sigh.
Point being… I am still working on getting comfortable with figuring out the whole sourdough thing, so a recipe that uses discard and does not have to be active and rising like the sun is more in my wheelhouse at the moment.
I say it a lot, and I’ll say it again: I love recipes that don’t require special ingredients.
If you can pull a recipe off with a quick trip to the pantry and a cup of fresh or frozen berries, you are in luck. Such is the case with these muffins. These Sourdough Discard Blueberry Lemon Muffins take less than 15 minutes to have mixed and in the oven- especially if everything is within reach for a quick grab.
Baking is so much easier – and so much more enjoyable – if you have your common baking ingredients and tools organized.
We recently remodeled our kitchen. One of my biggest priorities was making our kitchen island a baking center. Everything from the flour, sugar, and baking soda to mixing bowls and cooling racks is all on the same side of the island. While baking, I can just reach down in front of me and get what I need to mix something together quickly. Having everything organized is a time saver!
Make the sugary crumble topping first.

This crumble is made with three simple ingredients:
- Salted butter, 3 tablespoons
- Sugar, 1/2 cup
- Flour, 1/2 cup
Mix all ingredients together and set aside.

Mix the dry ingredients – except the berries.
The dry ingredients are:
- 2 cups AP flour
- 1 cup sugar
- 2 tsp baking powder
- 1/2 tsp baking soda
- 1 tbsp cornstarch
- Zest of 1/2 to 1 lemon

Then… fold in your fresh or frozen blueberries.

Next, mix together your wet ingredients in a separate bowl.
Dry ingredients include:
- 1 stick of salted butter, melted
- 2 large eggs
- 1/2 cup of sourdough discard
- 2 tablespoons sour cream
- 1 tsp vanilla
Don’t put the wet ingredients in a mixer – whisk it by hand to have a liquidy consistency, otherwise it will clump up from the sourdough.

Fold wet ingredients into dry ingredients until just combined.

The batter is ready to put into your greased muffin pan.
Tip here – make sure your pans are thoroughly greased. These muffins are very prone to sticking.
I used large muffin pans here – which makes about six to seven large muffins. With a regular sized muffin pan, I assume this will give you a good dozen.

Before heading to the oven – don’t forget the crumble topping.
Make sure to press the topping down into the batter so it stays on top of your muffins.

Bake in a 350-degree oven for 26 to 28 minutes for large muffins, 18 to 22 minutes for regular sized muffins.

You can cool them in the pan – but I usually take them straight to the cooling rack.
