Ingredients for this Gluten-Free Vanilla & Raspberry Sheet Cake
- Coconut oil. I like using coconut oil instead of butter because it makes the cake lighter and gives a nice coconut flavor. However, you can easily replace it with butter or even dairy-free butter.
- Sour cream adds moisture without thinning your cake batter, and that results in a cake with a very tender and very fine crumb. Moreover, because sour cream has more fat it gives the cake a velvety texture. The best substitute that you can use for sour cream is greek yogurt.
- Eggs. Eggs give structure to this cake. I’ve never tried making an egg-free version of this cake and I don’t believe that it can work.
- Sugar
- Vanilla Extract. I recommend that you use pure vanilla extract rather than artificial vanilla flavoring.
- Milk. I use lactose-free milk but you can substitute regular milk for dairy-free milk.
- Baking Soda
- Baking Powder
- Raspberries. The raspberries are used to make raspberry jam, therefore you can use both fresh or frozen raspberries.
- Lemon.
Frosting:
There are 2 types of frosting that go well with this cake.
- Greek Yogurt Frosting
The first one (and my favorite) is a slightly healthier alternative to traditional frostings. I understand that it might sound strange but trust me it goes so well with this cake.
To make the greek yogurt frosting you will need only 3 ingredients: Greek yogurt, vanilla extract, and sugar (or maple syrup). If you want to make it dairy-free, you can use coconut or other plant-based thick yogurts.
2. Cream Cheese Frosting
The second option is a simple cream cheese frosting.
For this frosting, you will need 4 ingredients: cream cheese, butter, vanilla, and powder sugar.

Step-by-step instructions
Here is how to make this Gluten-Free Vanilla & Raspberry Sheet Cake
Step 1: Make The Raspberry Jam
Add the raspberries, sugar, lemon juice, and lemon zest to a medium-sized pot set over high heat. Bring the mixture to a boil, once boiling use a potato masher or fork to break down and mash the berries. Continue to cook for 5-8 minutes or until the jam has reduced and thickened by 1/3. Remove from the heat and let cool. This should thicken as it cools.
Step 2: Make the Cake Batter
In a large bowl, mix together the coconut oil, sour cream, eggs, sugar, and vanilla. Add the flour, baking soda, baking powder, and salt. Mix until just combined, then slowly beat in the milk until fully combined.
Step 3: Bake
Pour the batter into the prepared pan. Take about 1/2 cup to 3/4 cup of the jam and dollop it by the tablespoon over the cake. Use a knife to lightly swirl the jam around, don’t over mix it. Bake 30-35 minutes, until the top is just set and no longer wiggly in the center. Remove and let cool completely before frosting.
Step 4: Make the frosting.
Greek Yogurt Frosting: In a bowl whisk greek yogurt sugar and vanilla extract, until well combined.
Cream Cheese Frostings: Combine butter and cream cheese in the bowl of a stand mixer and beat until creamy, well-combined, and lump-free. Add vanilla extract and salt and stir well to combine. With the mixer on low, gradually add powdered sugar until completely combined
Step 5: Frost the cake
Spread a thin layer of jam over the cake, then frost the cake all over. Add small spoonfuls of the jam to the frosting and gently swirl the jam into the frosting.

What flour to use to make this Gluten-Free Vanilla & Raspberry Sheet Cake?
I like to use my universal homemade gluten-free flour blend. Which is a mix of the following flours
- White Rice Flour
- Brown Rice Flour
- Sweet Rice Flour (Glutinous Rice aka Sticky Rice)
- Tapioca Flour (tapioca starch is the same as tapioca flour)
- Xanthan Gum
If you can’t make that one, you can try with any gluten-free flour mix (just make sure it contains xanthan gum because that helps in binding the dough). The final result using different flour mixes might vary slightly, depending on what flour your mix contains.
