Gluten-Free Birthday Cake

Difficulty: Intermediate Prep Time 15 mins Total Time 15 mins

Description

This gluten‑free birthday cake is soft, fluffy, and perfectly sweet — the kind of classic celebration cake everyone loves. Made with regular sugar and simple ingredients, it bakes up with a tender crumb and rich vanilla flavor that feels just like the birthday cakes you remember, only completely gluten‑free.

Ingredients

Servings

1 ³⁄₄ cup gluten-free 1:1 flour (I've used both Cup 4 Cup and Pilsbury)
2 tablespoons corn starch
2 ¹⁄₂ teaspoons baking powder
¹⁄₂ teaspoon baking soda
1 ¹⁄₂ cups sugar
3 room temperature eggs
¹⁄₂ cup melted butter
2 tablespoons neutral oil (avocado or canola)
1 cup milk
2 teaspoons vanilla
¹⁄₂ cup sour cream

Instructions

Preheat the oven to 325 degrees
Grease and line your pan (2, 8 inch pans or 1, 9x13pan)
In a small bowl, wisk together dry ingredients: flour, cornstarch, baking soda, baking powder, salt, sugar.
In a large bowl, add melted butter, oil, milk, vanilla and sour cream and blend until well combined.
Add room temperature eggs and combine until blended.
Add the dry ingredients to the wet ingredients and whisk or stir until just combined. Do not overmix — gluten‑free batter thickens as it sits.
Divide batter evenly between pans (or pour into a 9×13). Smooth the tops.
Bake 23–30 minutes for 8‑ or 9‑inch rounds, or 27–38 minutes for a 9×13 pan. The cake is done when the center springs back and a toothpick comes out with moist crumbs
