 CAKE BATTER (Adjusted from the Box)
  • 1 box Duncan Hines Perfectly Moist French Vanilla Cake Mix
  • 3 large eggs
  • ½ cup water
  • ⅓ cup extra virgin olive oil Or ½ cup vegetable oil   *Olive oil is fine here. Vanilla + lime will mask the flavor, and the reduced amount keeps it from tasting heavy.

  • 1 box lime Jello 3 oz
  • 1 cup boiling water
  • ½ cup cold water important
Lightly Sweet, Stable Whipped Cream (Beginner Friendly)
  • 1 cup cold heavy whipping cream

  10. Toothpick should come out clean.
  11. Cool completely

Lightly Sweet, Stable Whipped Cream Instructions (Step-by-Step)
  1. Step 1: Bloom the gelatin (do this first)
  2. In a small bowl, add:
  3. ½ teaspoon gelatin
  4. 1 tablespoon cold water
  5. Stir once.
  6. Let it sit 5 minutes.
  7. It will absorb the water and turn spongy or rubbery. This is correct.
  8. Step 2: Melt the gelatin
  9. Microwave the bloomed gelatin for 5–7 seconds.
  10. It should turn into a clear liquid.
    Clear bloomed the gelatin in a glass bowl above a wooden board.
  11. Let it cool 1–2 minutes.
  12. It should be warm, not hot.
  13. Step 3: Start whipping the cream (this is important)
  14. Pour cold heavy whipping cream into a mixing bowl.
  15. Use a hand mixer or whisk.
  16. Beat on medium speed until the cream thickens and forms soft peaks.
  17. Soft peaks look like this:
  18. When you lift the mixer, the cream falls over gently.
  19. It looks fluffy but not stiff yet.
  20. Step 4: Add powdered sugar and vanilla extract
  21. Beat again on medium until incorporated.
  22. Step 5: Add gelatin (this step makes it stable)
  23. Turn mixer to low speed.
  24. Slowly drizzle in the melted gelatin.
  25. Immediately increase speed to medium-high.
  26. Beat until stiff peaks form.
  27. Stiff peaks mean: The cream holds its shape. It does not slide or collapse.
  28. Do not overbeat or it will turn grainy.
HOW TO KNOW YOU’RE DONE
  1. ✔ Holds its shape on a spoon
  2. ✔ Looks smooth and airy
  3. ✔ Tastes lightly sweet, creamy, and clean
  4. If it looks:
  5. Too soft → whip 10-15 seconds more
  6. Grainy → stop immediately (you’re very close to butter)
  7. STORAGE
  8. Keeps 24 hours in the fridge without deflating
  9. Holds shape 2-4 hours at room temp
