Here are a few cleaner, more engaging (and less spammy) versions of your line:
🍫 Simple & clear
“Quick and Easy 2-Ingredient Dessert – Send me a ‘Hi’ and I’ll share it!”
✨ Friendly tone
“A quick and easy dessert made with just 2 ingredients! If you want the recipe, just send me ‘Hi’ 😊”
📱 Social media style
“2-ingredient dessert 😍 So easy! Comment ‘Hi’ and I’ll send it to you!”
🚫 More natural (less gimmicky)
“Quick and easy dessert with just 2 ingredients—message me if you want the recipe!”
If you want, I can also turn it into a viral Facebook post or make the dessert sound more irresistible with a hook.
