This gluten-free strawberry rhubarb cake recipe is perfect for those with dietary restrictions. The cake is made with a combination of almond flour and gluten-free flour, giving it a moist and tender texture. The cake is then topped with a layer of fresh strawberries and rhubarb, and finished with a crumbly streusel topping. The secret to this recipe is to use a gluten-free flour blend that contains xanthan gum to help bind the ingredients together. Serve this cake warm with a drizzle of honey for a delicious dessert.
