The ingredients don’t have specific amounts, as you’ll need to buy all those things anyway, and it depends on how many of the cookies come apart perfectly and how many Bugles look like cornucopias—you will likely have some leftover of both.

Separate the golden Oreo sandwich cookies and eat or save the side of the cookie with no frosting. I found the best way to separate the Oreos is by twisting the top off from the bottom.

On the side with the frosting, press a cornucopia-looking Bugle onto the cookie.

Press the mini M&M’s strategically in and around the bugle. Use extra frosting from cookies that didn't separate well if needed to get the M&M’s firmly placed on the cookies.

Alternatively, you can also use a tub of frosting if needed to pipe small amounts of frosting onto the M&M to get it very secure (I never found this necessary, but I also didn’t transport these to any gathering.)
