This dessert may be more challenging for inexperienced cooks, but is well-worth the effort.
- 1/4 cup of dry oats
- 2 cups of all purpose flour
- 1/4 teaspoon of salt
- 3/4 teaspoon of baking powder
- 3/4 cup of white sugar
- 1 1/2 sticks of frozen unsalted butter
- 1 1/2 teaspoons of vanilla
- 2 egg yolks
- For the fruit filling:
- 3 cups of berries- 1 cup of each berry that you choose. In this example, I have used red raspberries, blackberries, and cherries. Blueberries and strawberries are also great options!
- 2 teaspoons of lemon juice
- 1/3 cup of white sugar
- 2 teaspoons of cornstarch
- 1 teaspoon of apple cider vinegar
1) In a large bowl, combine the flour, salt, baking powder, and the 3/4 cup of white sugar. Mix together.
2) Using a cheese grater, grate the frozen sticks of butter into the mixture. Toss the bits of butter together with the flour as you go so that you may prevent the butter from clumping together.
3) Add in the vanilla, apple cider vinegar, and egg yolks. Begin to combine everything together with a fork. You will notice that this mixture is very dry. To finishing mixing, use your hands. Pick some up, squeeze it together with your palm and then break it apart back into the mixture. After some repetition the mixture should achieve a consistency that will hold together if you squeeze a clump but crumble apart easily.
4) In a baking dish, take slightly more than half of this mixture and press it down. There should be a dense layer at the bottom of the baking dish.
5) Add the 1/4 of oats to the rest of the mixture remaining in the bowl and toss together. Set aside.
6) In a separate bowl, add your berries, lemon juice, sugar, and the cornstarch. Mix together with a fork. While doing so, use the fork to smash some of the berries against the bowl.
7) Spread the berry mix over the base layer in the baking dish. Take the remaining oat mixture and crumble small bits over the top.
8) Bake at 375 degrees for 45 minutes or until the berries bubble through the top and the crumble turns a golden brown.
