This Gluten Free Strawberry Rhubarb Coffee Cake is a sweet, slightly tart cake that makes the perfect spring dessert. Since it’s technically a coffee cake so you could even serve it for breakfast or brunch.

Gluten Free Strawberry Rhubarb Coffee Cake
This Gluten Free Strawberry Rhubarb Cake is a Mother’s Day staple. It’s the cake that my dad has made my mom for Mother’s Day for as long as I can remember. Every year we have the same meal: steak, “the mushrooms” (my grandfather’s mushrooms cooked with tomatoes and herbs), a vegetable, potatoes, sometimes lobster, and then this delectable gluten free strawberry rhubarb coffee cake.

Yes, technically this cake is a coffee cake, so good news for you dessert lovers – you can eat it any time of the day! We’ve always had it as dessert though. And maybe leftover for breakfast the next morning?
I still live within 10 minutes from my parents so we usually still go there for dinner on Mother’s Day. Last year I made some grilled garlic shrimp and fried almonds with thyme as appetizers. I haven’t decided what I’ll bring this year, but I know one thing for sure – this gluten free strawberry rhubarb coffee cake will be there and it will be delicious.

The strawberry rhubarb compote is just sweet enough to mask the super tart rhubarb but not too sweet. And did I mention the crumb topping? That’s my favorite part. Looks like I’m finishing Whole30 up just in time to grab a slice of this fantastic cake. Enjoy! (I know I will be)
PS rhubarb is a vegetable so that counts towards your 5-a-day, right?

Gluten Free Strawberry Rhubarb Coffee Cake #SundaySupper
Ingredients
For the Filling:
- 1 lb strawberries diced
- 3 cups rhubarb diced
- 2 Tbsp fresh lemon juice
- 1 C sugar
- 1/3 C cornstarch
For the Cake:
- 3 C gluten free flour
- 1 tsp xanthan gum*
- 1 C sugar I used organic cane
- 1 Tbsp baking powder
- 1 tsp baking soda
- 1/2 tsp fine sea salt
- 1 C palm shortening
- 1 1/2 C unsweetened coconut milk room temperature
- 1 Tbsp white vinegar
- 2 large eggs room temperature
- 1 tsp vanilla extract
For the crumb topping:
- 1/4 C palm shortening measured then melted
- 3/4 C gluten free flour
- 1/8 tsp xanthan gum
- 3/4 C sugar
Instructions
- Preheat oven to 350 degrees and spray a 9x13 inch baking dish with non-stick spray.
To make the filling:
- Add the strawberries, rhubarb, and lemon juice to a medium sized saucepan, cover, and cook over medium heat for 5 minutes. Stir in the sugar and cornstarch and bring to a boil. Cook until the strawberries are soft and mashable, about 3 minutes. Remove from heat and cool while you make the cake.
To make the Cake:
- Add the flour, xanthan gum, sugar, baking powder, baking soda, and salt to a large bowl and whisk to combine. Add the shortening and use a fork to cut the shortening into the flour mixture until it forms coarse crumbs.
- In a separate medium bowl, whisk together the eggs, coconut milk, vinegar, and vanilla. Pour the wet ingredients into the dry ingredients and mix until combined.
- Pour half the cake batter into the prepared pan and spread it evenly over the bottom. Pour the strawberry rhubarb mixture over the cake batter and spread it evenly over the cake.
- Use a spoon to drop the remaining cake batter on top of the strawberry/rhubarb layer and carefully spread it out.
To Make the Crumb Topping:
- Add the melted palm shortening, flour, xanthan gum, and sugar to a small bowl and mix until it forms crumbs.
- Sprinkle the crumb topping evenly over the top of the cake.
- Bake at 350 degrees for 40-45 minutes or until a cake tester comes out clean.

This was super delicious! Made it just us the recipe said. The only issue I had was it was hard to spread out the top layer, So it didn’t cook totally even on the top. I’ll have to be a little more careful next time.
Can you use a Bundt pan for this cake?
No, a bundt pan wouldn’t be big enough.
Really delicious recipe, but the 70 calories per serving is WAY OFF! If cut into 16 squares it is 379 calories per square and that is with 3/4 cup less sugar total then the original recipe.
Hi Natalie, so glad you enjoyed the recipe! The calories was auto-populated when I switched recipe cards and I haven’t made my way through them all to check for accuracy.
