The 3 Simple Ingredients
You won’t believe how few ingredients you need:
- 1 box of lemon cake mix (sugar-free or regular, depending on preference)
- 1 cup fat-free Greek yogurt – This replaces oil and eggs while keeping the cake moist and tender.
- ¾ cup water – Adds just enough moisture to bring everything together.

That’s it! These three ingredients create a soft, luscious lemon cake with a light crumb and a hint of tang.
For an extra special touch, you can add a lemon glaze made from powdered sugar and fresh lemon juice—but that’s entirely optional.
Equipment Needed
One of the best parts about this recipe is its simplicity. Here’s all you’ll need:
- 1 large mixing bowl
- A whisk or hand mixer
- A loaf pan (8×4 inch or similar size)
- Nonstick spray or parchment paper
- Cooling rack
No need for stand mixers, multiple bowls, or fancy baking gadgets—just good old-fashioned mixing and baking.
Step-by-Step Instructions
- Preheat your oven to 350°F (175°C). Grease a loaf pan with nonstick spray or line it with parchment paper.
- Combine the ingredients. In a large bowl, add the lemon cake mix, Greek yogurt, and water. Mix until smooth and lump-free.
- Mix gently but thoroughly. Avoid overmixing; you just want all the ingredients fully incorporated.
- Pour the batter into your loaf pan. Spread it evenly with a spatula to ensure a smooth top.
- Bake for 35–40 minutes, or until a toothpick inserted in the center comes out clean.
- Cool completely before removing from the pan. Place on a wire rack to cool fully before glazing or slicing.
- Optional glaze: Combine ½ cup powdered sugar with 1–2 tablespoons of fresh lemon juice and drizzle over the cooled cake.
