1. Preheat & Prepare. Heat oven to 325°F (165°C). Grease and flour your Bundt pan generously.
2. Mix Dry Ingredients. In a large bowl, combine yellow cake mix and lemon pudding mix.
3. Add Wet Ingredients. Pour in oil, eggs, and 7UP. Beat on medium speed for 2–3 minutes until smooth.
4. Add Zest. Stir in lemon zest for that fresh, aromatic punch.
5. Bake. Pour the batter into the pan and bake 45–50 minutes, or until a toothpick comes out clean.
6. Cool. Let it rest 10 minutes before flipping onto a wire rack.
7. Glaze (Optional). Whisk together powdered sugar, lemon juice, and 7UP until smooth. Drizzle over cooled cake.

💡 Kitchen Tip: If you prefer a lighter touch, skip the glaze and dust with powdered sugar — it’s gorgeous either way!

What to Serve with Lemon 7UP Cake

This cake shines solo, but here are some pairing ideas:

• Fresh berries or lemon curd on the side.
• A dollop of whipped cream or a scoop of vanilla ice cream.
• Iced tea, lemonade, or even a sparkling cocktail.

Tips for Making It Perfect

• Use room-temperature eggs for better texture.
• Do not overmix. Gentle mixing keeps the cake fluffy.

• Make ahead: Wrap and refrigerate overnight — the flavor deepens beautifully.

Storage Instructions

• Room Temp: Keep covered up to 3 days.
• Refrigerate: Store up to 5 days.
• Freeze: Wrap slices in plastic and freeze up to 2 months. Thaw before serving.

Frequently Asked Questions

1. Can I use diet 7UP?
No — it won’t give the same texture or sweetness. Use regular 7UP or Sprite.

2. Can I make this gluten-free?
Yes! Use a gluten-free yellow cake mix and confirm the pudding mix is GF-certified.

3. Can I use butter instead of oil?
You can substitute melted butter for a richer flavor, but the cake will be slightly denser.

Bake at 325°F for 18–20 minutes or until golden.
