Ingredients:
FRUIT FILLING:

CAKE BATTER:
1 cup whole milk
½ cup apple cider vinegar
1 cup old-fashioned rolled oats
3 cups whole wheat flour, spooned and leveled
1 ⅓ cups brown sugar, packed
2 tsp baking soda
1 tsp cinnamon
1 tsp salt
1 cup cold, unsalted butter
2 large eggs
CRUMB TOPPING:
2 cups whole wheat flour
1 cup brown sugar, packed
1 cup old-fashioned rolled oats
1 tsp cinnamon
1 tsp salt
1 cup melted and cooled unsalted butter
Equipment:
Cake pans
Baking liners, optional
Bowls
Measuring cups and spoons
Whisk
Rubber spatula
Blender or food processor
Cutting board
Chef’s knife
Pot holders, dish cloths
Directions:
- Gather all the ingredients and equipment.
- For the fruit filling, wash the produce and prepare it as detailed in the ingredients list.
- Preheat the oven to 350ºF. Grease the pans with butter and dust with flour or line them with paper liners.
- For the batter, in a liquid measuring cup, combine the milk and vinegar, then set aside. This mixture will create curdled-looking buttermilk, which is what you want.
- Grind the oats in a blender or food processor. Place them in a large bowl with the flour, sugar, baking soda, and cinnamon. Mix well.
- Cut the cold butter into ½-inch pieces and scatter them over the flour mixture, breaking up any clumps. Using a pastry cutter or two knives, incorporate the butter until the mixture resembles crumbs, with some pieces the size of small peas, taking about 1 minute. Avoid overmixing to prevent the butter from melting into the flour.
- Beat the eggs into the milk mixture. Pour the wet mixture into the dry ingredients. Gently fold until blended and no flour remains.
- For the crumb topping, combine the flour, sugar, oats, cinnamon, and salt in a large bowl. Add the butter and fold until fully blended and no flour remains. It should clump together.
- Divide the batter and spread it evenly in both pans. Distribute the fruit across both pans. Add and spread the crumb topping evenly. Bake until golden and firm, 50 to 60 minutes.
