How to Make Gluten Free Rhubarb Coffee Cake

Ingredients

1/2 cup butter (I used Earth Balance® vegan butter alternative)
1 1/2 cup packed brown sugar
1 egg (or egg substitute of choice)
1 1/2 tsp pure vanilla extract
2 cups (270 grams) gfJules Gluten Free All Purpose Flour OR (280 grams) gfJules Gluten Free Multigrain Biscuit & Breakfast Baking Flour
1/4 tsp salt
1 tsp baking soda
1 cup sour milk
1 1/2 cup rhubarb, diced
½ cup sugar (you may use as little as 1/8 cup sugar if desired)
2 tsp ground cinnamon
¾ cup chopped walnuts (optional)

Step-by-Step Instructions

Preheat your oven to 350°F (175°C).
Prepare the measured sour milk and set it aside.
Using an electric mixer, beat the butter and brown sugar together until the mixture is light and fluffy.
Add the egg (or substitute) and the vanilla extract into the mixture, then beat again until well combined.
In a separate bowl, whisk together the gfJules Gluten Free flour, salt, and baking soda.
Gradually add the flour mixture and the sour milk to the butter-sugar mixture, alternating between the two, until everything is well blended.
Fold in the diced rhubarb gently to avoid breaking it down too much.
Line an 8×11 or 9×13 inch pan with parchment paper or lightly oil it. Pour the cake batter into the prepared pan and use a rubber spatula to smooth the top.
In a small bowl, combine the topping ingredients (sugar, cinnamon, walnuts) and sprinkle them evenly over the cake batter.
Bake in your preheated oven for 30-35 minutes. However, if you use an 8×11 pan, check occasionally as the baking time can extend up to 45 minutes depending on your oven. The cake is done when a toothpick or knife inserted into the center comes out clean and the center is no longer jiggly.
If the walnuts on top are browning too quickly, cover the top of the cake loosely with aluminum foil during baking.
Once baked, remove the cake from the oven and let it cool on a wire rack before slicing and serving.

This recipe yields about 6 servings of this scrumptious rhubarb coffee cake.

How to Store Gluten Free Rhubarb Coffee Cake

To keep the cake fresh, store it in an airtight container at room temperature for up to three days. If you want to keep it longer, you can refrigerate it for up to a week. For longer storage, consider freezing the cake; wrap it tightly in plastic wrap or aluminum foil and place it in a freezer-safe container for up to three months. When you’re ready to enjoy it, thaw it overnight in the refrigerator and reheat it gently in the oven.

Tips to Make Gluten Free Rhubarb Coffee Cake Perfect

Choosing Rhubarb: Use fresh, bright green rhubarb stalks for the best flavor and texture. Avoid any that look wilted or damaged.
Sour Milk Substitute: If you don’t have sour milk on hand, create a substitute by adding 1 tablespoon of vinegar or lemon juice to 1 cup of regular milk. Let it sit for about 5 minutes before using.
Adjusting Sweetness: Depending on your preference, feel free to reduce the amount of sugar used in the recipe. This can work well, especially with the tang of rhubarb balancing the flavors.
Texture Variations: For a different texture, you can mix in other fruits like blueberries or apples that complement the rhubarb’s tartness.

Flavor Variations

Consider adding other flavors to this coffee cake to make it your own. Here are some delicious options:

Citrus Twist: Add the zest of one lemon or orange to bring a bright, fresh flavor to your cake.
Cinnamon Swirl: Create a cinnamon swirl by adding a layer of cinnamon-sugar mixture in the middle of the batter before baking.
Nutty Crunch: Use different kinds of nuts like pecans or almonds in place of walnuts for added crunch and flavor.
Fruity Addition: Incorporate some fresh strawberries or raspberries with rhubarb for an added layer of fruity flavor that balances the tartness.

Pro Tips for Success

Ensure all your ingredients, especially the gluten-free flour, are fresh for the best results.
Using room temperature ingredients can help with even mixing and a smoother batter.
Invest in a good quality baking pan. Non-stick options work best for easy release of your coffee cake.
Keep an eye on the baking time as ovens can vary. Be patient, and always check for doneness with a toothpick instead of relying solely on time.
