- 1 tablespoon butter, softened
- 1 (8 ounce) package cream cheese
- 1 cup white sugar
- 3 eggs
- 1/4 cup vegetable oil
- 2 cups sliced fresh strawberries
- 1 cup strawberry puree
- 1 cup rhubarb puree

- Preheat oven to 350 degrees F (175 degrees C). Grease 2 loaf pans evenly with butter.
- Combine cream cheese and sugar in a large bowl; beat with an electric mixer until smooth. Add eggs one at a time, beating well between each addition. Pour in vegetable oil; beat until fluffy. Fold in strawberries, strawberry puree, rhubarb puree, and rhubarb gently.
- Mix brown rice flour, tapioca starch, garbanzo-fava bean flour, coconut flour, baking powder, xanthan gum, and salt together in a separate bowl. Fold into the strawberry-rhubarb mixture until thoroughly blended. Add walnuts and vanilla extract to the batter.
