Ingredients
Method
- Make the crumb topping: whisk flour, sugars, cinnamon, and salt, then rub in cold butter until clumpy. Chill.
- Whisk the remaining flour, baking powder, baking soda, and salt in a separate bowl.
- Cream softened butter and sugar until fluffy, beat in eggs and vanilla, then alternate adding dry mix and yogurt.
- Toss fruit with 1 tbsp flour, fold two-thirds into batter, reserving rest.
- Grease a 9-inch pan, preheat oven to 350°F. Layer half the batter, reserved fruit, remaining batter, and chilled topping. Bake 45–55 minutes until golden and a toothpick tests clean. Cool 10 minutes in pan.
- Run a knife around the edge, lift cake out, dust with powdered sugar, and slice.
Notes
If using frozen fruit, add it directly from the freezer and expect the bake time to nudge closer to 55 minutes. The cake slices cleanest when cooled for at least 20 minutes, but I rarely wait that long.
