which opens as expected into Carbide Create (though there is a warning about open vectors):
but selecting open vectors:
and then deleting addresses that.
The design represents the raised design of the cookie, so one will need surrounding geometry, select:
Offset Vectors:
to some reasonable dimension:
Then shift-click to deselect the border geometry:
and delete to clean up:
Select everything:
and scale to suit your stock:
Then re-size the stock:
Select everything:
Group Vectors
Align Vectors
to the center of the stock:
Ungroup Vectors
Select only the surrounding geometry:
and use Offset Vectors again:

Apply
Select everything except for the original border geometry:
and assign a V Carving toolpath to a suitable depth:
(might want to use a smaller tool)
Select the two border geometries:
Assign a Pocket Toolpath down to tab height:
Select only the first offset border geometry:
and apply Tabs (unless using workholding which will secure things w/o tabs):
OK
Assign a Contour toolpath which starts at the bottom of the previous toolpath:
to arrive at:
and re-arrange toolpaths for minimal tool changes by dragging:
