Here’s the blueprint: Dairy Queen’s iconic vanilla soft serve laced with chewy chocolate brownie pieces, chocolate candy chunks and cocoa fudge ripple, served in a freshly made waffle cone.

Total calories: 500. Fat grams: 18.5. Dietary fiber: 1 g. Sodium: 200 mg. Carbs: 55 g. Protein: 8 g. Manufacturer’s suggested retail price: $3.39.

If you want a waffle cone that’s dipped in chocolate, add 30 cents, plus 130 calories and 8.5 fat grams. It’s worth it … and so are you.

Dairy Queen announced this newfangled way to serve a Blizzard — in a cone instead of a cup — in conjunction with its latest Flavor of the Month concoction: Confetti Cake. That’s vanilla soft serve spiked with pieces of white cake and icing. “Confetti Cake” is a weird name. Somebody must have gotten dibs on “Birthday Cake” ice cream. I’m smelling Baskin-Robbins.

While DQ is pushing Confetti Cake in a waffle cone, you can get any Blizzard flavor in a freshly made cone. My go-to Blizzard is Chocolate Xtreme. But I don’t stop at Xtreme. Like Spinal Tap pushing its amps to 11, I go to Xtreme measures to make my Blizzard over-the-top, beyond chocolate. How I long for the old days, when DQ served chocolate soft serve. I look at vanilla as a dare.

Customers can ask for “extra stuff” (the mix-ins) in their Blizzard for 69 cents more. What I do is ask for extra “extra stuff” — that’s three times the regular amount of brownie pieces, chocolate chunks and cocoa fudge ripple. And I go with the chocolate-dipped cone. I know, it’s a desperate cry for help. Now my $3.39 Chocolate Xtreme Blizzard has jumped the $5 barrier.

I would ask ’em to squirt some hot fudge on top, but the people behind me are talking already. I’m sensitive about my chocolate “problem.”

Blizzards come in four sizes: mini, small, medium and “how many spoons would you like?” The amount served in a Waffle Cone Blizzard is mini. They would offer the other sizes, but most people have put their snow shovels away for the summer.

Dairy Queen introduced the Blizzard — vanilla soft serve swirled with candy, fruit and/or nuts — in 1985. It’s the best-selling treat on the menu. They’re so thick that every DQ Blizzard is turned upside down before it’s forked over (with a spoon) to the customer. The No. 1 Blizzard is OREO Cookie.
