Gluten Free Lemon Donut Bundt Cake

Gluten Free Lemon Bundt Cake That Actually Tastes Like Real Cake

There’s something about a lemon cake that just feels like sunshine in dessert form—bright, fresh, and a little nostalgic. And if you’ve ever baked gluten-free, you know the struggle… dry, crumbly, or worse—gritty. This gluten free lemon donut bundt cake is the opposite of all that.

It’s soft, moist, and packed with real lemon flavor thanks to fresh zest, lemon juice, and a little trick that makes a big difference (don’t skip it). It’s the kind of cake you can serve to anyone—gluten-free or not—and they won’t know the difference. Some other great gluten free dessert recipes are Gluten Free Maple Peach Cake, Gluten-free Cinnamon Sugar Zucchini Donuts, and Gluten Free Banana Crumb Cookies.

Why This Gluten Free Lemon Donut Bundt Cake Works

Most gluten-free cakes fall flat because the flour doesn’t hydrate properly. That’s where this recipe is different.

Here’s what makes it better:

• Bob’s Red Mill 1:1 flour → gives structure without dryness
• Buttermilk + sour cream → adds richness and moisture
• Oil + butter combo → best of both worlds (moist + flavor)
• Lemon zest rubbed into sugar → boosts citrus flavor naturally
• 15-minute batter rest → eliminates that gritty texture

That last step? It’s the secret. Don’t skip it.

How to Make Gluten Free Lemon Donut Bundt Cake

1. Prep

Preheat oven to 350°F.
Grease your bundt pan very well—gluten-free cakes are more delicate and tend to stick.

---

2. Boost the Lemon Flavor

In a bowl, combine the sugar + lemon zest.

Rub it together with your fingers until fragrant.
This step releases the oils and makes the lemon flavor pop.

Whisk together in a separate bowl:

• flour
• baking powder
• salt

3. Mix the Wet Ingredients for this gluten free lemon cake

In a large bowl, whisk together:

• buttermilk
• sour cream
• eggs
• oil
• melted butter
• lemon juice
• vanilla
• lemon extract

---

4. Combine

Gradually add dry ingredients to wet.

Mix until just combined.
The batter will be slightly thick and a little lumpy—that’s exactly what you want.

---

5. Let the Batter Rest (Don’t Skip!)

Let the batter sit for 15 minutes.

This allows the gluten-free flour to fully hydrate so your cake turns out soft—not gritty.

---

6. Bake

Pour into prepared bundt pan.

Bake at 350°F for 45–55 minutes, or until a toothpick comes out clean.

Let cool in the pan for 10–15 minutes, then carefully invert onto a wire rack.

Make the lemon glaze for bundt cake

• 1 cup powdered sugar
• 2–3 tablespoons fresh lemon juice

Whisk and drizzle over cooled cake.
