Serve this cake warm, scooped straight from the slow cooker into small bowls or onto plates, letting the glossy limoncello glaze drip down the sides. It pairs beautifully with a dollop of lightly sweetened whipped cream or a scoop of vanilla or lemon sorbet to echo the spritz theme.
For adults, offer chilled limoncello spritzes or a simple glass of prosecco on the side; for a non-alcoholic pairing, try sparkling lemonade over ice with a twist of lemon. At a pool party, I like to set the slow cooker on the “warm” setting with a ladle and stack of small bowls so guests can help themselves between swims.
Ingredients
- 1 box (about 15 oz) sugar-free lemon cake mix
- 1 can (12 oz) Sprite Zero or 7UP Zero
- ¼ cup limoncello liqueur
- Nonstick cooking spray
Optional Light Lemon Glaze
- ½ cup powdered zero-calorie sweetener
- 1–2 tablespoons fresh lemon juice
- 1 teaspoon lemon zest
Instructions
- Lightly coat the inside of your slow cooker with nonstick cooking spray.
- In a large mixing bowl, combine the sugar-free lemon cake mix, Sprite Zero, and limoncello. Stir just until combined—do not overmix.
- Pour the batter into the prepared slow cooker and spread it evenly.
- Cover and cook on High for 2–2½ hours or Low for 3–4 hours, until a toothpick inserted into the center comes out clean.
- Let the cake cool for 15–20 minutes before slicing.
- If using the glaze, whisk together the powdered sweetener, lemon juice, and lemon zest, then drizzle over the cooled cake.
WW-Friendly Tips
- Cut into 12 servings for about 3–5 WW Points per slice (may vary depending on the cake mix brand).
- Garnish with fresh lemon zest or a few berries for extra flavor without adding many points.
