This gluten-free cinnamon coffee cake features a tender, moist crumb with a swirl of warming cinnamon spice. Combining gluten-free flour, butter, Greek yogurt, and a cinnamon-sugar topping with oats, this easy-to-make cake bakes to a golden finish that's perfect with hot drinks. The oat crumble topping adds a satisfying crunch while the cinnamon swirl throughout enhances every bite.

The first snowfall of the season had just started when my kitchen filled with that unmistakable cinnamon sugar smell drifting from the oven. I remember pressing my nose against the oven glass like a kid, watching the oats turn golden while snowflakes settled on the windowsill. This coffee cake became an instant ritual that winter.
My sister texted me from across the country asking for the recipe after I sent her a photo of the still warm cake, slightly tilted because I could not wait for it to cool before slicing. Now she makes it whenever she needs her house to feel like home.
Ingredients
- Gluten free all purpose flour blend: Using a blend with xanthan gum already included saves a step and ensures proper structure without any grittiness
- Greek yogurt: This is the secret ingredient that keeps the crumb tender and adds subtle tang while replacing some butter
- Brown sugar: The molasses in brown sugar creates a deeper, more caramel like flavor that pairs perfectly with cinnamon
- Gluten free rolled oats: Certified gluten free oats add texture and nuttiness to the topping while keeping it safe for those with sensitivities
- Unsalted butter: Starting with softened butter helps it cream properly with sugar for a light, airy batter
Instructions
- Get everything ready:
- Preheat your oven to 350°F (175°C) and line an 8x8 inch pan with parchment paper so the cake lifts out easily later
- Mix the dry foundation:
- Whisk together the gluten free flour blend, baking powder, baking soda, and salt in a medium bowl
- Build the creamy base:
- Cream softened butter and granulated sugar until fluffy, then beat in eggs one at a time before stirring in vanilla
- Add the tender element:
- Fold in the Greek yogurt until completely smooth
- Bring it together:
- Gently fold the dry ingredients into the wet mixture just until combined, being careful not to overmix
- Create the cinnamon swirl:
- Mix brown sugar and cinnamon in a small bowl
- Layer the magic:
- Spread half the batter in the pan, sprinkle with cinnamon sugar, then drop remaining batter on top and spread gently to cover
- Top with crunch:
- Stir together oats, brown sugar, melted butter, and cinnamon, then sprinkle evenly over the batter
- Bake until golden:
- Bake for 38 to 42 minutes until a toothpick inserted in the center comes out clean
- Patience pays off:
- Let the cake cool in the pan for 15 minutes before lifting it out to cool completely
There is something about watching steam rise off a warm slice while snow falls outside that makes everything feel right in the world.
Making It Your Own
I once added chopped pecans to the topping on a whim and discovered they toast beautifully alongside the oats, adding even more depth to the final crunch.
Serving Suggestions
This cake is irresistible slightly warm, when the cinnamon swirl is still soft and the oats are at their crispest. A light dusting of powdered sugar makes it feel special enough for guests.
Storage And Freezing
Wrap any leftovers tightly and they will stay moist on the counter for three days. For longer storage, slice the cake first then freeze individual portions wrapped well for up to three months.
- Thaw frozen slices overnight in the refrigerator
- Rebrief briefly in the oven to restore the crisp topping
- Never store warm cake or condensation will make it soggy
This recipe has become my go to for snowy weekends and unexpected company alike.
