How to Make This Gluten-Free Lemon Blueberry Cake: Step-by-Step

Alright, let’s get baking! Here’s the breakdown of how to create this delicious cake. Don’t worry, this recipe is easy to follow, and even if you’re new to gluten free baking, you can totally nail this.

Prep the Blueberries: If using fresh blueberries, wash and dry them very well. Once dry, toss them in 1/2 tablespoon sorghum flour and set aside. If using frozen blueberries, do not defrost the berries before adding them to the batter. Toss them in 1/2 tablespoon sorghum flour and keep them in the freezer until ready to fold them into the batter. This helps prevent them from sinking to the bottom of the cake!
Prep the Oven and Pans: Preheat the oven to 350°F. Brush two 8-inch cake pans lightly with vegetable oil or cooking spray and line the bottom with parchment paper. This ensures the cake releases easily.
Combine Dry Ingredients: In a medium bowl, sift together the sorghum flour, sweet rice flour, tapioca starch, millet flour, xanthan gum, baking powder, baking soda and salt. Set aside. Sifting is key for a light and airy cake!
Whip the Egg Whites: Using a hand mixer, whip the egg whites in a medium bowl, starting on low speed and increasing to high speed until soft peaks form. When the beater is pulled out a peak should rise and the very tip should fall. Set aside. This adds volume and lightness to the cake.
Cream Butter and Sugar: In the bowl of a stand mixer fitted with the paddle attachment or a bowl with a hand mixer, cream together the butter and sugar over medium speed until light and fluffy, about 3 minutes. This is where the magic starts!
Add Lemon Zest, Vanilla, and Egg Yolks: With the mixer on low speed, mix in the lemon zest, followed by the vanilla and egg yolks, scraping down the sides as needed. That lemon zest is going to make this cake sing!
Alternate Dry and Wet Ingredients: Mix in the sour cream, then, with the mixer on low, slowly add the dry ingredients in three batches, adding the milk and lemon juice in between, scraping down the sides after each addition, and mixing until just combined. Be careful not to overmix!
Fold in Egg Whites: Using a silicone spatula, fold in ⅓ of the whipped egg whites to loosen the batter. Then carefully fold in the remaining whipped egg whites until almost combined. This keeps the cake light and airy.
Fold in Blueberries: Fold in the blueberries until evenly distributed. Divide the batter among the prepared baking pans and use an offset spatula to spread it into an even layer.
Bake: Bake for 34-36 minutes until the cake springs back when gently pressed in the middle and a toothpick comes out dry or with a few moist crumbs.
Cool: Remove from oven. Let cool in the pan for 10 minutes, then run a clean knife around the outside and overturn the cake onto a wire rack to cool completely. To do this, I place a wire rack over the baking pan and, holding the pan and the rack together, carefully flip the cake to release. Peel off the parchment paper, then place a wire rack over the top, and carefully flip it right-side up.
Frost: Once cool, make the lemon cream cheese frosting according to this recipe.
Decorate and Serve: Frost the cake. For a layer cake, spread ½ cup of frosting between each layer. Spread a very thin layer of frosting on the top and side. Use a bench scraper or offset spatula to smooth and scrape the frosting off the sides as pictured. Smooth or swirl the top of the cake, then decorate as desired with more blueberries, lemon slices, and/or lemon blossoms. Slice and serve.

And there you have it! A beautiful, bright, and delicious gluten-free lemon blueberry cake. This cake is truly something special; the cake will be the star of any gathering.

Pro Tips for the Perfect Gluten-Free Lemon Blueberry Cake

Want to take your cake to the next level? Here are a few of my favorite pro tips:

Room Temperature Ingredients: Make sure your butter, eggs, and sour cream are at room temperature. This helps them emulsify properly, resulting in a smoother batter and a more tender cake.
Don’t Overmix: Overmixing gluten-free batter can lead to a tough cake. Mix until just combined, and then gently fold in the egg whites and blueberries.
Use a Kitchen Scale: For best results, use a kitchen scale to measure your ingredients. This ensures accuracy and consistency.
Parchment Paper is Your Friend: Lining your cake pans with parchment paper makes it easy to release the cakes without sticking.
Let It Cool Completely: Resist the urge to frost the cake while it’s still warm. Let it cool completely to prevent the frosting from melting.

Common Mistakes to Avoid

We all make mistakes in the kitchen – it’s part of the fun! But here are a few common pitfalls to avoid when making this cake:

Using the Wrong Gluten-Free Flour Blend: Not all gluten-free flour blends are created equal. I recommend using the blend specified in the recipe for best results.
Overbaking the Cake: Gluten-free cakes tend to dry out more quickly than traditional cakes. Keep a close eye on the cake while it’s baking, and test for doneness with a toothpick.
Skipping the Xanthan Gum: Xanthan gum acts as a binder in gluten-free baking, helping to create structure and prevent the cake from crumbling. Don’t skip it!
Not Tossing Blueberries in Flour: Tossing the blueberries in flour helps prevent them from sinking to the bottom of the cake.

Variations to Try

Want to put your own spin on this recipe? Here are a few fun variations to try:

Add a Lemon Glaze: Drizzle a simple lemon glaze over the cooled cake for an extra burst of lemon flavor.
Use Different Berries: Substitute raspberries, blackberries, or strawberries for the blueberries.
Add Poppy Seeds: Add 2 tablespoons of poppy seeds to the batter for a subtle nutty flavor and a beautiful speckled appearance.
Make Mini Cakes: Bake the batter in muffin tins to create individual mini cakes.
Create a Lemon Blueberry Bundt Cake: Bake in a bundt pan and adjust baking time accordingly.

How to Store Your Gluten-Free Lemon Blueberry Cake

This cake is best stored in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 5 days. If you’re freezing the cake, wrap it tightly in plastic wrap and then in foil. It can be frozen for up to 2 months. Let it thaw completely before serving.

Frequently Asked Questions

Can I use a different gluten-free flour blend? While I recommend using the specified blend for best results, you can experiment with other blends. Just be aware that the texture and flavor of the cake may vary.
Can I make this cake dairy-free? Yes, you can substitute the butter with a dairy-free butter alternative and the sour cream and milk with dairy-free alternatives.
Can I use frozen blueberries? Yes, you can use frozen blueberries. Do not thaw them before adding them to the batter, and toss them in flour to prevent them from sinking.
My cake is dry. What did I do wrong? Overbaking is the most common cause of dry gluten-free cakes. Be sure to keep a close eye on the cake while it’s baking and test for doneness with a toothpick.
My blueberries sank to the bottom of the cake. How can I prevent this? Tossing the blueberries in flour helps prevent them from sinking. You can also try using smaller blueberries.
