It’s blueberry season! I love pie, but I’m usually too lazy to make a pie crust most nights. If you haven’t heard of a buckle before, it has a cake bottom topped with lots of blueberries and then finished off with an oat crumble.
Since I know many of you are on oil-free diets, I adapted this recipe to be oil-free, soy-free, and nut-free. It does use sugar, but you could experiment with the recipe to use your favorite sweetener.
You could also use a gluten-free baking mix in place of the whole wheat pastry flour and make it gluten-free, too.
You layer fresh blueberries over the cake batter and then top that with the oat crumble. Then bake and eat!
You could make this with any berry you have on hand, but it’s actually usually made with blueberries. I’m thinking of trying one with peaches and using vanilla extract in place of the lemon oil.

This was so good! I’m always looking for oil free baking recipes and I couldn’t believe the texture and flavors of this one. I couldn’t stop eating it, and as a bonus, it’s pretty easy to make too. Thank you.
P.S. I can’t get the stars to register but this is a definite five star.

This is by far the best dessert recipe I’ve made in a long time. You can’t tell it’s oil free, the cake has a wonderful texture and the crumble is perfect. I’ve been making this since you first posted it and everyone loves it (even my non vegan friends). Definitely a perfect dessert for summer or any time. I agree with the above comment. Definitely five stars.

Great combination of moist cake, crumble and juicy berries. I baked it the full 40 minutes to get the center cooked. It’s disappearing really fast!

Thank you Kathy for this fantastic recipe. I’ve used it twice to make the Blueberry Buckle. I used whole grain Einkorn flour in lieu of the whole wheat flour, and substituted Erythritol for the sugar. Einkorn flour requires less liquid, so I made some ad-hoc adjustments on the go until consistency of the dough seemed right. Today, I made it with apples (with the skin on cut into blueberry sized chunks), raisins soaked in rum extract, and ceylon cinnamon. I also coarsely ground the rolled oats for the topping, and added 1 TBSP margarine.. Baked for the full 40 minutes in a Breville toaster oven. Hubby’s reaction: “This is it”. Guess this is my go-to recipe from now on!!

Very good! I made only roughly about as directed, a bit sloppy on the measurements (as always for me).I didn’t have sugar, so I used powder sugar instead and it was still OK. I only had old fashioned oats which did not really thicken the crumble the same as regular oats would, so I added a bit more oats and dropped that on. I subbed a squeeze of lemon juice for the lemon flavor, added some vanilla to the batter and some cinnamon to the crumble. I under baked a little, because I prefer under to over baked (30 minutes). This recipe seems really good for “relaxed” bakers. I made all those small changes, and it was still very tasty and with nice textures. I’d say this is hard to mess up! I’ll be trying many variations!

Wow, thanks for this recipe for blueberry buckle. As a child, I loved blueberry buckle even more than blueberry pie. the thicker the layer of blueberries between the cake layer and the crumble layer the better. I will be trying this very soon.

I have made this twice, subbing in ap flour, vanilla for lemon and frozen berry mix for blueberries.
Fantastic!
Thanks for the recipe!
