How to Make the Ultimate Ice Cream Brownie Sundae

Ah, summer holidays. That glorious time when the kids are home, the sun is (hopefully) out, and the phrase “I’m bored” echoes through the house...

But fear not—we have a solution that’s equal parts fun, delicious, and very good at keeping everyone entertained: the Ice Cream Brownie Sundae.

This isn’t just a dessert—it’s an activity, a bribe, a reward, a sweet moment of quiet (yes, we see you hiding in the kitchen with a spoon). And it all starts with five gloriously simple steps to make the best brownie sundae you'll have all summer.

Step 1: Scoop Your Ice Cream – The Creamy Base for Your Brownie Sundae

Start with a generous scoop of vanilla ice cream—or any favourite flavour that brings joy. You want a base that’s creamy, classic, and chilled to perfection.

Some of our go-to options for a dreamy ice cream brownie sundae:

  • Jude’s Vanilla Clotted Cream is ultra creamy, with a lovely rich finish
     
  • Booja Booja is one of local neighbours and make deliciously wonderful vegan ice cream with their New Edition Vanilla has our hearts. 
     
  • Or even that trusty supermarket tub—because dessert doesn't need to be complicated.

Mix it up if you dare: a swirl of caramel, a sprinkle of chocolate chips—this is your easy summer dessert, so make it yours.

Step 2: Add Your Brownies – Fudgy, Flavour-Packed, and Utterly Essential

This is where the magic happens. Take your brownies (preferably ours, of course ?) and cut or crumble them over your ice cream.

We’re talking fudgy edges, gooey middles, and just enough decadence to feel like you’re cheating summer. Want to mix things up?

Try:

Warm them slightly for that hot-cold meltiness that makes this a no-bake summer dessert dream.

Step 3: Drizzle Your Favourite Sauce – Chocolate, Caramel, or Classic Strawberry

Now we get saucy. Drizzle your sauce of choice:

  • Chocolate sauce (our personal fave – deep, rich, and melty)
  • Caramel (golden, buttery bliss)
  • Strawberry (for that retro sundae nostalgia)

Want to go full wild-child? Try all three. That’s what makes this a fun summer dessert for kids and grown-ups alike.

Step 4: Sprinkle on Marshmallows aka Clouds of Happiness

Time to bring in the fluff. A generous handful of mini marshmallows—or as we lovingly call them, clouds of happiness—on top of your sundae adds playful sweetness and a soft chewy contrast.

We use vegan marshmallows, so everyone can enjoy the party (zero animal products, all the joy). Bonus: they look adorable and taste even better.

Step 5: Top It Off with Nuts – Crunch, Texture, and Grown-Up Vibes

Final flourish: chopped nuts for that crucial crunch and flavour contrast. Go fancy with:

  • Toasted hazelnuts
  • Salted peanuts
  • Crushed pistachios (for that pastel pop)

It’s the step that says: “Yes, I made this. And yes, it’s amazing.”

Pro Tips from the expert dessert creators:

  • Add sprinkles or a flake for extra fun.
  • Use sundae glasses for a Pinterest-worthy look.
  • Let the kids build their own—DIY sundae bars = instant holiday activity.

Movie Night Magic or Holiday Treat?

Whether you're looking for a kid-friendly summer treat, a mid-afternoon pick-me-up, or a new way to serve dessert at your next BBQ, the ice cream brownie sundae is your all-weather hero.

Pair it with:

  • A family movie night
  • A playdate dessert bar
  • A just-because Tuesday reward

And the best part? You’ve found a fun, no-bake way to enjoy brownies in summer—when ovens are off-limits and cool treats reign supreme.
