Low Sugar Gluten Free Cinnamon Coffee Cake

This tender coffee cake gets its soft, moist crumb from sour cream and a rich butter base, with a cinnamon-swirled streusel layer running right through the center for that classic bakery-style ribbon. A second scattering of streusel on top bakes up into a golden, clumpy crust that adds real texture to every bite. The batter comes together simply — creamed butter and eggs, folded gently with a gluten free flour blend — so the crumb stays tender rather than dense or gummy. A light drizzle finishes the warm cake with a touch of vanilla, pooling into the cracks of the streusel for extra flavor in every square. It's the kind of cake that looks like it took more effort than it did, and it's a solid pick for anyone keeping an eye on added sugar without giving up a proper coffee cake fix.

¾ cup granulated sugar
Chef's tip
Use the same volume. Baking behavior varies by blend: some brown faster or stay softer, while others brown less. Follow the package's baking guidance and start checking a few minutes early.
2 large eggs
1 tsp vanilla extract
1 cup sour cream
2 cups gluten free flour blend
1 ½ tsp baking powder
½ tsp baking soda
½ tsp salt
½ tsp xanthan gum (omit if your flour blend already contains it)

For the streusel

⅔ cup packed light brown sugar
Chef's tip
Use the same volume. Brown-sugar replacements vary in moisture, spread, and browning, so follow the package's baking guidance and start checking a few minutes early.
1 ½ tsp ground cinnamon
¼ cup gluten free flour blend
3 tbsp unsalted butter, cold and cut into small pieces

For the glaze

½ cup powdered sugar
Chef's tip
Follow the package's conversion to powdered sugar. In frosting or glaze, add liquid gradually - replacements can absorb it differently.
2 tbsp milk
¼ tsp vanilla extract

Instructions

1
Preheat the oven to 350°F (175°C). Grease a 9×9-inch baking pan and line the bottom with parchment paper.
2
Make the streusel: In a small bowl, combine the brown sugar, ground cinnamon, and 1/4 cup gluten free flour blend. Add the cold butter pieces and work them in with your fingertips until the mixture resembles coarse, clumpy crumbs. Set aside.
