Gluten-Free Coffee Cake

• 1/2 cup unsalted butter softened, for cake
• 1 cup granulated sugar for cake
• 2 teaspoons vanilla extract
• 2 large eggs
• 1/2 cup sour cream
• 1/2 cup buttermilk
• 2 cups gluten-free all-purpose baking flour for cake
• 1 teaspoon baking powder
• 1/2 teaspoon baking soda
• 1/2 teaspoon salt for cake
• 1 cup gluten-free all-purpose baking flour for streusel
• 1/2 cup light brown sugar packed
• 2 tablespoons granulated sugar for streusel
• 2 teaspoons cinnamon
• 1/8 teaspoon salt for streusel
• 1/3 cup unsalted butter melted, for streusel

1. Preheat oven to 350u0b0F.
2. Spray pan liberally with nonstick cooking spray. Set aside.
3. Place butter, sugar, and vanilla into mixing bowl. Use mixer to cream ingredients together on medium-high speed until smooth, 1-2 minutes. Add eggs, sour cream, and buttermilk, and continue beating until mixture is light and fluffy, about 1 minute.
4. Sift gluten-free flour, baking powder, baking soda, and salt into bowl. Mix on low speed, scraping down sides of bowl with rubber spatula as needed, until a smooth, thick batter forms.
5. Scrape batter into pan with rubber spatula and smooth it into an even layer.
6. Place gluten-free flour, brown sugar, granulated sugar, cinnamon, and salt in a large mixing bowl. Stir with a fork to combine. Drizzle melted butter into bowl and mix with fork until mixture forms large crumbs. Sprinkle crumble evenly over cake batter.
7. Bake on middle rack of oven until topping is golden and toothpick inserted in center comes out clean, 35-45 minutes.
8. Check to see that coffee cake is done. Remove from oven or add time as needed.
9. Allow cakes to cool in pans for 15-20 minutes before serving. To store, cover tightly with aluminum foil or store in an airtight container and keep at room temperature for 1-2 days, refrigerate for up to 1 week, or freeze for up to 2-3 months.
