Step‑by‑Step Instructions for Strawberry Rhubarb Jam Cake
Step 1: Preheat Oven
Begin by preheating your oven to 350°F (175°C). This crucial step ensures your Strawberry Rhubarb Jam Cake bakes evenly. While the oven warms up, prepare your pans, a vital step for a successful bake!
Step 2: Prepare Cake Pans
Grease three 6-inch cake pans with oil and line them with parchment paper. Don’t forget to grease the parchment as well, then lightly dust the pans with gluten-free flour for easy removal. This preparation allows the cakes to release beautifully after baking.
Step 3: Mix Dry Ingredients
In a large mixing bowl, combine 1 cup cassava flour, ½ cup brown rice flour, ⅓ cup tapioca starch, and 1 cup powdered sugar. Add in 1 teaspoon vanilla powder, ½ cup light brown sugar, 1 teaspoon baking powder, ½ teaspoon baking soda, ¼ teaspoon salt, and 1 teaspoon xanthan gum. Mix thoroughly until all dry ingredients are well incorporated and free of lumps.
Step 4: Combine Wet Ingredients
In a medium bowl, mix together ½ cup strawberry rhubarb jam (reserve the remaining for filling), ⅓ cup oil, ½ cup apple sauce, ½ cup water, and 1 tablespoon vinegar. Stir until well combined. The mixture should be smooth and slightly glossy, preparing to blend perfectly with the dry ingredients.
Step 5: Combine Mixtures
Create a well in the center of your dry mixture and pour in the wet ingredients. Gently stir until just combined; it’s okay if there are a few lumps remaining. This careful blending guarantees a moist and fluffy Strawberry Rhubarb Jam Cake once baked.
Step 6: Transfer and Bake
Evenly distribute the batter into the prepared pans, smoothing the tops with a spatula. Place the pans in the preheated oven and bake for about 35 minutes. Check for doneness by inserting a toothpick into the center; it should come out clean when fully baked.
Step 7: Cool and Assemble
After baking, remove the pans from the oven and let them cool in the pans for 10 minutes. Carefully transfer the cakes to a wire rack to cool completely. Once cooled, frost the top of the first layer with a generous amount of jam filling, add the second layer, and repeat the process. Finish by frosting the top layer and decorating as desired with your favorite fruits or edible flowers.

Expert Tips for Strawberry Rhubarb Jam Cake
-
Ingredient Freshness: Always use fresh ingredients, especially the baking powder and baking soda, as they are key to achieving the desired rise in your Strawberry Rhubarb Jam Cake.

Strawberry Rhubarb Jam Cake Recipe FAQs
How do I choose ripe strawberries and rhubarb for my jam cake?
Absolutely! Select bright red strawberries that are fragrant and have no dark spots. For rhubarb, the stalks should be firm and crisp, with a vibrant color. Avoid stalks that are wilting, limp, or have a dull hue, as these may not provide the best flavor for your cake.
What’s the best way to store leftover Strawberry Rhubarb Jam Cake?
To preserve the freshness of your Strawberry Rhubarb Jam Cake, place it in an airtight container in the refrigerator. It will stay moist for up to 3 days. You can also cover it loosely with plastic wrap to maintain its texture while allowing some air circulation.
Can I freeze my Strawberry Rhubarb Jam Cake? How?
Yes, you can enjoy this cake even later! To freeze, wrap individual slices or whole layers tightly in plastic wrap and then in aluminum foil for extra protection. It can be frozen for up to 2 months. When you’re ready to enjoy, simply thaw it overnight in the refrigerator, and for a quick treat, microwave slices for about 10-15 seconds or warm them in the oven at 350°F (175°C) for a few minutes.
What if my cake comes out too dense?
Very! To avoid a dense cake, make sure not to overmix the batter when combining wet and dry ingredients. Lumpy batter is perfectly fine! Additionally, ensure your leavening agents (baking powder and baking soda) are fresh and properly measured, as they are crucial for achieving the right rise in your Strawberry Rhubarb Jam Cake.

Absolutely! This recipe is both vegan and gluten-free, making it suitable for many dietary restrictions.
