This unique lemon cake takes inspiration from the classic Arnold Palmer drink—blending bold black tea with bright lemonade. The result is a soft, moist cake with a subtle tea depth and refreshing citrus flavor, all made effortlessly in a slow cooker.
Ingredients
- 1 (15.25 oz) box lemon cake mix
- 1¼ cups strong brewed sweet black tea (cooled)
- 1 cup prepared lemonade (divided)
- ¾ cup for batter
- ¼ cup for glaze
- Optional: nonstick spray or butter (for greasing)
Instructions
1. Prep the Slow Cooker
Lightly grease a 5–6 quart slow cooker with butter or nonstick spray.
This helps prevent sticking and gives lightly golden edges.
2. Prepare the Tea
Brew strong black tea (about double strength).
Let it cool completely before using.
👉 Strong tea = better flavor in the final cake.
3. Mix the Batter
In a large bowl:
- Add lemon cake mix
- Pour in 1¼ cups cooled tea
- Add ¾ cup lemonade
Stir until smooth and lump-free.
The batter will be slightly thinner than usual—this is normal.
4. Add to Slow Cooker
Pour batter into the greased slow cooker.
Spread evenly.
5. Cook
Cover and cook:
- LOW: 2 to 2½ hours
- or HIGH: 1½ to 2 hours
Cake is ready when:
- top looks set
- a toothpick comes out clean
👉 Avoid opening the lid too often—heat escapes and slows cooking.
6. Make the Glaze
Once cake is done:
- Drizzle the remaining ¼ cup lemonade over the warm cake
It will soak in and add extra moisture + tangy flavor.
7. Cool & Serve
Let the cake rest for 10–15 minutes before serving.
Scoop directly from the slow cooker or carefully lift out.
