It sounds like you’re talking about a very simple homemade treat, but I’d need a little more detail to identify it. Many popular sweets use only three ingredients (like fudge, peanut butter bars, or condensed-milk desserts). 😋
Could you tell me one of these?
- What did it look like? (color, soft/hard, chocolate-like, etc.)
- Was it sweet or savory?
- Did it come as a square/block you cut into pieces?
If you want, you can also send a photo, and I can likely identify the recipe and give you the exact 3-ingredient version to make at home.
