Step‑by‑Step Instructions for Strawberry Rhubarb Jam Cake
Step 1: Preheat and Prepare Pans
Begin by preheating your oven to 350°F (175°C). While the oven heats, prepare three 6-inch cake pans by greasing them generously with oil, then lining the bottoms with parchment paper. Dust the pans lightly with gluten-free flour, ensuring an even coating; this will help the cakes release effortlessly after baking.
Step 2: Mix Dry Ingredients
In a large mixing bowl, combine the cassava flour, brown rice flour, tapioca starch, powdered sugar, and vanilla powder. Next, stir in the light brown sugar, baking powder, baking soda, salt, and the xanthan or guar gum. Whisk well until all dry ingredients are evenly blended, ensuring there are no lumps; this delicious blend will form the foundation of your Strawberry Rhubarb Jam Cake.
Step 3: Prepare Wet Mixture
In a separate medium bowl, whisk together the wet ingredients, including strawberry rhubarb jam, oil, applesauce, water, and vinegar. Mix until the ingredients are smooth and fully incorporated, creating a lovely, fragrant mixture. This wet combination adds moisture and flavor, enhancing the overall taste of your cake.
Step 4: Combine Mixtures
Create a well in the center of the dry ingredients, then carefully pour the wet mixture into this well. Stir gently until just combined, taking care not to overmix; it’s perfectly fine if small lumps remain. This ensures your Strawberry Rhubarb Jam Cake will be light and tender once baked.
Step 5: Bake the Cakes
Evenly distribute the batter among the prepared cake pans, using a spatula to smooth the tops. Place the pans in the preheated oven and bake for approximately 35 minutes. Your cakes are ready when they are golden and a toothpick inserted into the center comes out clean. The wonderful aroma will fill your kitchen!
Step 6: Cool the Cakes
Once baked, remove the cake pans from the oven and allow them to cool in the pans for about 10 minutes. Carefully transfer the cakes to a wire rack to cool completely, as this step is crucial for a perfect assembly. Ensure that the cakes are entirely cool before you begin the layering process of your Strawberry Rhubarb Jam Cake.
Step 7: Assemble the Cake
When the cakes are completely cool, place the first layer on a serving plate. Pipe a border of frosting around the edge of the layer and fill the center with a generous amount of strawberry rhubarb jam. Repeat this process with the next layer, ensuring that each layer is evenly spaced and beautifully filled before topping it with the final layer of cake.
Step 8: Frost and Decorate
With the layers stacked, apply frosting generously over the top and sides of the cake. Use an offset spatula to create a smooth finish, and feel free to get creative with your decorative elements. Adding edible flowers or fresh fruit on top can elevate your Strawberry Rhubarb Jam Cake, making it an eye-catching centerpiece for any gathering!

Expert Tips for Strawberry Rhubarb Jam Cake
- Room Temperature Ingredients: Ensure all ingredients are at room temperature to promote better mixing and improve the cake’s texture.
- Avoid Overmixing: Gently combine the wet and dry ingredients; overmixing can lead to a denser, less fluffy cake.
- Jam Thickness Matters: When using homemade strawberry rhubarb jam, make sure it’s thick enough to hold layers together without making the cake soggy.
- Baking Time: Keep an eye on the cakes during baking; start checking for doneness a few minutes early, as oven temperatures can vary.
- Cooling is Key: Allow the cakes to cool completely before assembling; this prevents melting frosting and keeps layers intact.
- Experiment with Flours: Feel free to substitute or blend flours to find your preferred texture, but remember to adjust proportions for the best Strawberry Rhubarb Jam Cake!
