riddle - A Pi day What Am I?

Another Pi day themed puzzle like my other one.

I contain 5 letters,

I only have 1 syllable,

I can be referred to as money,

Or I can be the foundation of something wonderful (and quite popular too),

I can come before a word similar to “crazy” to be something sweet,

I have silent letters,

Google describes me as thick and elastic.

What Am I?

Answer

I think you are:

Dough

I think the first three lines are self explanatory.

Can be the foundation of something wonderful

Bread/cookie dough

Can be followed by a word similar to "crazy" to be something sweet

"Nut", to make doughnut/donut

Has silent letters

The gh are silent.

Google describes me as thick and elastic

When you search dough, the little box that pops up describes dough as such.
