cake
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 cup salted butter, room temperature
- 3/4 cup granulated sugar
- 1 tablespoon vanilla extract
- 3 large eggs
- 1/2 cup non-fat plain Greek yogurt
- 1/4 cup whole milk
- 2 medium Granny Smith apples, peeled, quartered, cored and thinly sliced
Preparation
crumb topping
- In a medium bowl combine the walnuts, flour, brown sugar, granulated sugar and cinnamon. Whisk together using a fork.
- Use the fork to stir while pouring in the melted butter. You'll notice the mixture will become a crumb-like texture. Break up any large crumbs with the fork. Place the bowl in the refrigerator while you make the batter.
cake
- Preheat oven to 350°F. Spray a 9-inch spring form pan with cooking spray, set aside.
- In a medium bowl, whisk together the flour, baking powder and baking soda.
- In the bowl of a stand mixer, or using an electric mixer, beat the butter for 2 minutes until light and fluffy. Add the sugar and vanilla extract and continue to beat for an additional 1-2 minutes. Add the eggs one at a time until incorporated. Stop the mixer and scrape down the sides.
- With the mixer on low speed, add a third of the dry ingredients. Mix until just combined.
- Mix in the Greek yogurt, followed by another third of the dry ingredients. Mix until just combined.
- Mix in the milk, followed by the last third of the dry ingredients. Mix until just combined, about 1 minute. Do not overmix. The batter will be quite thick and it's okay if it has a few lumps.
- Spread the batter into the prepared pan. Top with the sliced apples followed by the crumb topping.
- Bake for 45-55 minutes or until a skewer inserted in the center of the cake comes out mostly clean (or with just a few crumbs). Let cool for 15-20 minutes before removing from spring form pan. Serve warm or at room temperature.
