Blueberry Rhubarb Sourdough Scones

Scones, tender, flakey, full of yumminess… something I used to make years ago. I had made some several years ago but they were sort of heavy. So, I assumed all gf scones were generally pretty sad until last spring when I attempted them with leftover sourdough starter, generally called discard. I had created the starter using brown rice flour and was looking for a way to use up the excess sourdough starter. I couldn’t find a recipe for blueberry sourdough gf scones, so I took a gluten-based recipe and reconfigured it to make with a one for one blend: specifically, Bob’s Redmill 1-1 Blend. I used a half cup of thick starter.

A week later I made the recipe again but added finely chopped rhubarb stalks (never the leaves; poisonous) and made them somewhat smaller and a different shape. Made with real dairy like actual butter and whole milk.  I ate the first one when it was still warm. It was heaven in a scone. Crisp outside, tender inside. Bursts of sweet blueberries and tangy rhubarb gave the perfect taste experience. It was just as good as the blueberry ones from this spring, maybe even better. I have never eaten such tender gluten free baked items as these sourdough scones. The crumb was moist and the texture perfect and they are red, white and blue, patriotic! A great breakfast or company treat that no one will believe are gluten free.

I cut them in more of a square shape, so I got 12 squarish scones, a bit smaller than the 8 wedges that are commonly done but I wanted smaller as those big wedges are just a bit too much for my afternoon snack! It is hard to make skinny long wedges plus I didn’t think they would freeze well; break up. These rectangular ones are quite sturdy considering how delicate the crumb is.

I don’t know what you can sub in for the sourdough starter. Perhaps some plain Greek yogurt? Maybe you should just make starter so you can bake these scones.  You could use vegan butter and I think it will be delicious!

I didn’t take any pictures except of the done cooling scones; wasn’t thinking about this blog, I guess. Next time I make them I will take a few.

I don’t know what flavor I will make next, but I do know there will be many next times. Frozen blueberries worked so well; keeping the dough chilly as I mixed it with a wooden spoon and then kneading it with my bare hands. So, other frozen fruits are in my freezer…. Trust me, it is easy to make and utterly decadent despite no icing beyond a couple teaspoons of sugar sprinkled on top. I may make it with some with cut up frozen strawberries next week!

Angie’s Rhubarb and Blueberry Sourdough Scones (GF of course)


200 grams 1-1 Gluten free flour blend; I used Bob’s Redmill but King Arthur 1-1 blend works well too

50 grams almond flour

100 grams granulated sugar

2 ½ tsp. baking powder

¼ tsp. salt

7.5 Tbsp of cold butter

1 cup of finely chopped rhubarb; 1/3 inch size is good

1 half cup of fresh or frozen blueberries

½ cup sourdough starter (Use the discard if you are creating discard)

1 large egg

1/3 c cold whole milk


Mix all dry ingredients in a large mixing bowl. Cut in cold butter with a butter cutter or 2 knives. Until it is tiny pebbles of dough and butter.

Add the egg, starter and ¼ c of the milk. Mix to break up egg and start the blending process. Add in the chopped rhubarb and the frozen blueberries (or fresh) and continue stirring. As it gets to be a thick dough dump it out on your breadboard with all the dry bits and hand knead it to coalesce it into a thick dough. Form it into a large square about 9 inches across. Cut into 12 squares; cut in three strips; then across to make 12 squares or rectangles depending on how square your original rolled out dough was. Spread them out on a cookie sheet that you have sprayed with cooking spray. Sprinkle with 2 tsp. of granulated sugar or chunky sugar if you have some. Put the sheet in a cold place to chill while you heat the oven. Heat to 355 degrees.

Put the sheet in to bake. If you have a convection cycle they will be done in about 20 minutes; the outside needs to be light brown, bottom browned and they look done. I tried 18 min but that wasn’t enough. If you don’t have convection they will likely take a few more minutes.  Let cool on pan for 5 minutes and move to a rack. They cooled rapidly and I couldn’t resist eating one while it was warm. So tasty and I loved how patriotic my scones look!

Enjoy! I they freeze nicely; vacuum sealing would be a good way to go about it if you are freezing for more than a week.
