Essential Ingredients
Here’s what you’ll need to make this delicious dish:
Fresh Rhubarb: Look for firm stalks with vibrant color; avoid any that looks wilted or brown.
Gluten Free Flour Blend: A good quality blend will give the best texture; I prefer one with xanthan gum included.
Sugar: Regular granulated sugar works perfectly; feel free to use coconut sugar for a healthier twist.
Butter: Use unsalted butter for better control over salt levels; melted butter blends beautifully into the batter.
Eggs: Fresh eggs help bind everything together and add moisture; be sure they’re at room temperature.
Baking Powder: Make sure it’s fresh for optimal rising; check expiration dates regularly.
Cinnamon: A dash adds warmth and flavor complexity; feel free to increase if you love cinnamon.

How to Make gluten free rhubarb cake
Preheat your oven: Start by preheating your oven to 350°F (175°C). Grease and flour an 8-inch square baking pan to prevent sticking.
Prepare the rhubarb: Chop about two cups of fresh rhubarb into small pieces. The tartness will shine through once baked, so don’t skip this step.
Mix dry ingredients: In a large bowl, whisk together gluten free flour blend, sugar, baking powder, cinnamon, and a pinch of salt until thoroughly combined.
Combine wet ingredients: In another bowl, beat together melted butter and eggs until smooth. Add in chopped rhubarb and mix gently to combine flavors without bruising the fruit.
Combine mixtures: Slowly fold the dry ingredients into the wet mixture using a spatula until just combined; be careful not to overmix as this can make the cake dense.
Bake: Pour the batter into your prepared pan and spread evenly. Bake in the preheated oven for 35-40 minutes until golden brown and a toothpick comes out clean from the center.
Cool and serve: Once out of the oven, let the cake cool in the pan for about 10 minutes before transferring it onto a wire rack to cool completely. Slice and enjoy!
Now that you’ve made this delightful gluten free rhubarb cake, get ready to savor each bite filled with nostalgia and sweetness!
