Don't use vanilla paste in a recipe that needs extract for volume. If a recipe says "stir in extract," paste works great. If it says "add extract to the milk," same thing.
Paste is thicker. It's a syrup, not a liquid. In very, very delicate recipes—like a super light sponge cake—the extra thickness might throw off the moisture. Just a tiny bit.
But for 99% of what you bake? It's a perfect swap. Your snickerdoodles will not sue you.
The Bottom Line (Get It? Because It's Coffee Chat)
So, you've got extract and need paste, or vice versa? Use a 1:1 ratio. Don't overthink it. The vanilla gods will forgive you.
You're making food for people you love. The love matters more than the speckles. I promise.
Now go bake something. And save me a slice, will you? I'll bring the coffee.
