Ingredients
2½ tbsp white vinegar
2½ cups milk (or unsweetened almond, cashew, or coconut milk)
3¾ cups all-purpose gluten-free flour with xanthan gum (e.g., Pillsbury or Bob’s Red Mill)
3 tsp baking powder
1 cup granulated sugar
½ cup light brown sugar, packed
¼ tsp salt
1 tbsp pure vanilla extract
1 cup butter, melted (or dairy-free alternative like Smart Balance)
3 large eggs, room temperature
Filling:
1 tbsp ground cinnamon
1 cup light brown sugar, packed
Topping:
1 cup light brown sugar, packed
½ cup granulated sugar
1 tbsp ground cinnamon
½ cup butter, melted (or dairy-free alternative)
1⅓ cups all-purpose gluten-free flour with xanthan gum
Instructions
1. Preheat oven to 350°F (175°C). Grease a 9″ x 13″ glass or metal baking pan with gluten-free cooking spray.
2. Add white vinegar to milk in a large measuring cup or bowl. Stir and let sit 5 minutes to create a buttermilk substitute.
3. In a large bowl, whisk together gluten-free flour, baking powder, salt, granulated sugar, and brown sugar.
4. Pour in melted butter and vanilla extract. Mix on low with a hand mixer until combined.
5. Beat in eggs one at a time, mixing until smooth after each addition.
6. Gradually pour in the milk mixture, about 1 cup at a time, mixing until the batter is smooth. Set aside.
7. In a small bowl, whisk together filling ingredients: brown sugar and cinnamon.
8. Pour half of the batter into the prepared pan and spread evenly.
9. Sprinkle the cinnamon-sugar filling over the batter.
10. Pour the remaining batter over the filling and spread gently to cover.
11. In a medium bowl, make the topping: whisk brown sugar, granulated sugar, cinnamon, and gluten-free flour. Add melted butter and stir until crumbly.
12. Sprinkle the crumb topping evenly over the batter.
13. Bake on the middle rack for 30 minutes. At the 30-minute mark, cover loosely with foil to prevent over-browning.
14. Continue baking for 20–30 minutes, or until a toothpick inserted in the center comes out clean.
15. Remove from oven and let cool in the pan for 20 minutes before slicing.
16. Store leftovers in an airtight container at room temperature for up to 3 days, or freeze for longer storage.
Notes
Use a high-quality gluten-free flour blend with xanthan gum for best results. Not all blends behave the same!
Always use the spoon-and-level method when measuring flour to avoid a dense cake.
For dairy-free: use almond milk and Smart Balance or another plant-based butter.
To freeze: wrap slices tightly in plastic wrap and store in a freezer-safe bag for up to 3 months. Thaw at room temperature.
