Gluten-Free Cinnamon Coffee Cake - Soft, Cozy, and Perfect With Coffee
Ingredients
Method
- Preheat and prep: Heat your oven to 350°F (175°C).Grease an 8x8-inch square pan and line it with parchment, leaving overhang for easy lifting.
- Make the cinnamon swirl and crumble: In a small bowl, mix 1/2 cup brown sugar with 2–3 teaspoons ground cinnamon and a pinch of salt. For the crumble, combine 1/3 cup gluten-free flour, 1/3 cup brown sugar, 1 teaspoon cinnamon, and a pinch of salt. Stir in 3 tablespoons melted butter until clusters form.Set both aside.
- Whisk the dry ingredients: In a large bowl, whisk 1 1/2 cups gluten-free all-purpose flour with 2 tablespoons cornstarch, 1 1/2 teaspoons baking powder, 1/4 teaspoon baking soda, and 1/2 teaspoon fine sea salt.
- Mix the wet ingredients: In a separate bowl or large measuring cup, whisk 2/3 cup granulated sugar, 1/4 cup neutral oil, 2 large eggs, 1 teaspoon vanilla, 1/2 cup sour cream, and 1/3 cup milk until smooth.
- Combine gently: Pour the wet mixture into the dry ingredients. Stir with a spatula just until no dry streaks remain. The batter should be thick but spreadable.Avoid overmixing.
- Layer the cake: Spread half the batter into the pan. Sprinkle half the cinnamon-sugar mixture over it. Dollop the remaining batter on top and gently spread.Sprinkle the remaining cinnamon sugar, then scatter the crumble over everything.
- Bake: Bake for 32–40 minutes, until the top is golden and a toothpick inserted in the center comes out mostly clean with a few moist crumbs. If the top browns too quickly, tent loosely with foil for the last 10 minutes.
- Cool and glaze (optional): Let the cake cool in the pan for at least 20 minutes. If you’d like, whisk 1/2 cup powdered sugar with 1–2 tablespoons milk and a drop of vanilla, then drizzle over the slightly warm cake.
- Slice and serve: Lift the cake out using the parchment and cut into squares.Serve warm or at room temperature with coffee or tea.

Common Mistakes to Avoid
- Using the wrong flour blend: Not all gluten-free blends behave the same.Choose a quality 1:1 blend. If it doesn’t include xanthan gum, add 1/2 teaspoon to the dry mix.
- Overmixing the batter: Stir just until combined. Overmixing can make the cake tough or gummy.
- Skipping the cornstarch: It helps mimic cake flour and improves tenderness.Don’t omit unless your blend already has a high starch content.
- Overbaking: Check early. Gluten-free cakes can dry out quickly. Pull it once a toothpick shows moist crumbs, not a wet batter.
- Uneven layering: Spread the middle layer gently so the cinnamon sugar stays in a distinct stripe instead of clumping.
Alternatives
- Dairy-free: Use plant-based milk and dairy-free yogurt or sour cream, plus vegan butter for the crumble.The texture stays soft and moist.
- Egg-free: Replace the eggs with 2 flax eggs (2 tablespoons ground flax + 6 tablespoons water, rested 5 minutes). The crumb will be slightly denser but still delicious.
- Lower sugar:</-strong> Reduce the granulated sugar in the batter to 1/2 cup and cut the cinnamon sugar by a couple of tablespoons. Skip the glaze.
- Nutty variation: Add 1/2 cup chopped pecans or walnuts to the crumble for extra crunch and flavor.
- Spice twist: Add a pinch of cardamom or nutmeg to the cinnamon sugar for a bakery-style flavor boost.
- Pan swap: Bake in a 9-inch round or an 8×4-inch loaf pan.Adjust baking time as needed and check early.
FAQ
Can I use almond flour instead of a gluten-free all-purpose blend?
Almond flour won’t work as a direct swap here. It lacks the starch structure needed for the light, cakey crumb. If you want to include almond flour, replace up to 1/4 of the blend and keep the rest as a 1:1 GF flour.
What if my gluten-free blend already has xanthan gum?
That’s perfect.
Don’t add extra. Too much gum can make the texture gummy or bouncy. Just use the blend as is and follow the recipe.
How do I know when the cake is done?
Look for a golden top and a toothpick that comes out with a few moist crumbs but no wet batter.
The center should spring back lightly when pressed.
Can I double the recipe?
Yes. Bake in a 9×13-inch pan and increase the bake time to around 40–50 minutes. Start checking at 38 minutes and tent with foil if the top browns too fast.
Is coffee required in a “coffee cake”?
No.
Coffee cake is meant to be enjoyed with coffee, not necessarily made with it. This recipe focuses on cinnamon flavor and a tender crumb.
Can I add fruit?
Absolutely. Fold in 1 cup of small diced apples or blueberries to the batter.
If using juicy fruit, toss it with a teaspoon of flour first to help prevent sinking.
Why is my cake crumbly?
It may be overbaked or your flour blend may be too heavy on rice flour. Measure flour carefully, don’t overmix, and watch the baking time closely.
