Lemon Blueberry Sheet Cake
So you’re craving something sweet, tangy, and way too pretty to resist—but also not in the mood to babysit a layer cake that takes three mixing bowls and your will to live? Same. Enter the Lemon Blueberry Sheet Cake: your new favorite “wow, you actually baked that?” dessert that’s secretly low-effort and high-reward. It’s zesty, fruity, and just the right amount of extra. Basically, it’s sunshine in cake form—and it doesn’t judge if you eat it for breakfast.
Why This Recipe Is Awesome
Let’s get one thing straight—this cake is ridiculously easy. No complicated folding, no fancy equipment, no culinary degree needed. If you can stir, pour, and not burn things (most of the time), you’re golden.
Here’s why you’ll love it:
- It’s idiot-proof. Even I didn’t mess it up—and I once burned instant noodles.
- That lemon-blueberry combo? Chef’s kiss. It’s like summer had a flavor baby.
- It feeds a crowd, but also makes an amazing “leftovers-for-me-only” situation.
- Sheet cakes are the lazy baker’s best friend—frosting? Optional. A drizzle of glaze? Perfect.
Ingredients You’ll Need
Grab your whisk and your sass—here’s what you’ll need:
For the Cake:
- 2 cups all-purpose flour (aka cake foundation)
- 2 tsp baking powder (because flat cake is sad cake)
- ½ tsp baking soda
- ½ tsp salt
- 1 cup granulated sugar (sweet, but not too sweet)
- ½ cup unsalted butter, softened (don’t even think about using margarine)
- 2 large eggs
- 1 cup plain Greek yogurt (for that soft, fluffy texture)
- ¼ cup milk
- 2 tbsp lemon zest (zest = flavor power)
- ¼ cup fresh lemon juice
- 1½ cups fresh blueberries (or frozen, if that’s your vibe)
- 1 tsp vanilla extract (because why not?)
For the Glaze:
- 1 cup powdered sugar
- 1–2 tbsp lemon juice (depending on how tangy you like it)
- Optional: a handful of extra blueberries for dramatic presentation
Step-by-Step Instructions
- Preheat like you mean it.
Set your oven to 350°F (175°C). Don’t skip preheating unless you enjoy uneven, sad cakes. - Mix your dry team.
In a bowl, whisk together flour, baking powder, baking soda, and salt. Set aside. Pretend you’re on a cooking show for extra flair. - Cream the butter and sugar.
In a big bowl, beat butter and sugar together until it’s light and fluffy—like whipped sunshine. Add in eggs, one at a time, then toss in yogurt, milk, lemon juice, zest, and vanilla. - Combine forces.
Slowly add your dry ingredients into the wet mixture. Stir until everything’s best friends—smooth, but don’t overmix or your cake will turn chewy (and not in the good way). - Fold in the blueberries.
Toss your blueberries with a tablespoon of flour first—this keeps them from sinking to the bottom. Then gently fold them into the batter like you’re tucking them into bed. - Bake it, baby.
Pour the batter into a greased 9×13-inch sheet pan. Bake for 30–35 minutes, or until a toothpick comes out clean. - Cool and glaze.
Mix powdered sugar with lemon juice until smooth. Once the cake cools (patience, my friend), drizzle that zesty glaze all over. Watch it shine like edible jewelry.

A quick note: This cake isn’t exactly “health food,” but it’s packed with antioxidants from the blueberries and a hit of Vitamin C from the lemons. Plus, a slice of this after a long day is basically therapy. Moderation is key—unless you’re having a bad day. Then, all bets are off. 😌
Common Mistakes to Avoid
- Skipping preheating. Rookie move. Cold ovens make unevenly baked cake sadness.
- Overmixing the batter. You’re baking a cake, not kneading bread. Gentle vibes only.
- Not tossing blueberries in flour. Unless you want all your berries chilling at the bottom like rebels.
- Pouring glaze on a hot cake. You’ll end up with a sticky puddle instead of a glossy finish.
- Forgetting zest. The zest is the lemon flavor—don’t cheat yourself.
Alternatives & Substitutions
- Greek Yogurt: Swap with sour cream for a tangier bite.
- Blueberries: Raspberries, blackberries, or even chopped strawberries work too.
- Flour: Want a gluten-free version? Use 1:1 gluten-free flour blend. It actually works here.
- Glaze: Skip it for a “coffee cake” vibe, or swap for a cream cheese frosting if you’re feeling extra.
Personal tip: I once tried this with orange zest instead of lemon—still good, but let’s be real, lemon wins every time.
FAQ (Frequently Asked Questions)
Q1: Can I use margarine instead of butter?
Technically yes, but why hurt your soul like that? Butter = flavor. End of discussion.
Q2: Can I make this ahead?
Totally. Bake it, cool it, and store it covered at room temp for up to 2 days—or fridge it for up to 5.
Q3: What if I don’t have fresh lemons?
Bottled juice will do in a pinch, but you’ll miss out on that zingy zest magic.
Q4: Can I freeze this cake?
Absolutely! Freeze in slices or whole (without glaze) for up to 3 months. Defrost, glaze, and pretend it’s freshly baked.

Yes! Just reduce the bake time to 18–20 minutes. Bonus: you get built-in portion control (unless you eat six).
