Strawberry Rhubarb Jam Cake is Moist and Tasty!

Sweet and delicious strawberry rhubarb jam is mixed into the cake batter and is also in between the finished and frosted layers.
Finish, frost, and decorate the cake however you like. I topped mine with a thin later of store-bought vegan frosting for a “naked caked” look along with some edible flowers!
To start, preheat the oven to 350 degrees F and, using vegan butter, grease the bottoms and sides of three 6-inch cake pans (or one 10″ inch). Place a parchment paper circle in the bottom of each pan, grease the top of it as well and then dust some GF flour on the bottom and sides.
In a large mixing bowl, stir together the dry ingredients. In a medium-sized bowl, stir together all the wet ingredients. Stir the wet ingredients into the dry ingredients and mix until well combined. There will still be some lumps. It’s not supposed to be perfectly smooth. I’ve used my own blend of gluten-free flours. If you prefer, use 1 3/4 cups of your favorite flour mix on one like THIS ONE from Bob’s Red Mill instead.
Pour evenly between the three cake pans and bake at 350 degrees F for 35 minutes or until the center springs back and a toothpick inserted in the center comes out clean.
Once completely cooled, make a ring of frosting on the first layer of the cake. This is going to hold some jam.
Fill the middle with about 3 or 4 tablespoons of strawberry rhubarb jam. Add the second layer and repeat. Finish by placing the third layer on top and frosting and decorating as you like.
I used a thin coat of store-bought frosting for a more “naked cake” look and added some edible flowers.
Also, I sliced some strawberries and a bit of the rhubarb and dehydrated them to use along with the edible flowers.
I love the colorful combination!
