Eric plans to play it safe and simple, recalling that this tack worked well for him in the last quickfire. Malika says the chaos surrounding Seth's departure reminded her to chill out (pun intended, suckas) and have fun. Not so much for Morgan, who is running around like a crazy man. He explains that he's not doing a "sundae," but rather a mint chocolate chip cookies and milk "Sunday" because he's recently divorced, and he spends Sundays with his son, who loves Oreos and mint chocolate chip ice cream. He hopes to win for his son. Danielle, who dreams of opening up an old-fashioned soda shop, is doing a take-off on Neapolitan with her rocky road ice cream. Yigit says that he's keeping his emotions in check after Seth's abrupt withdrawal because the name of the game is professionalism. He says that he's been obsessed with ice cream since he grew up in Turkey, but he never had chocolate chip cookie dough, so he's designing his dessert with things he didn't have growing up that he's come to love now. Donuts are fried, sauces are drizzled, scoops are shaped, and the clock finally ticks down.

Zac is first to present his dessert to "Ga(i)l(e) Squared." He makes the show even gayer than before by creating a "Black Forest Is Burning" sundae of panko-crusted, deep-fried cherry vanilla ice cream. Oh, Zac-y, I love you more than words can say. Next, Erika offers up her Chocolate Banana S'Mores Frangelico sundae with peanuts and Godiva semi-sweet chocolate on top of a graham cracker. Morgan chokes up as he explains his "Sunday Snack" of an Oreo mint chocolate chip ice cream sandwich with warm and foamy, mint syrup-infused chocolate milk. Heather made a Vanilla Fudge Twirl Bananas Foster sundae, with a brown sugar-butter rum sauce, fried bananas, and cinnamon cream. Next is Eric's Natural Vanilla with Sautéed Peaches, Brandy & Crisp. Malika embellished her cookies and cream with malted chocolate caramel sauce and bananas. Yigit has plated a decadent and luscious Peanut Butter & S'Mores Cookie Dough sundae. Finally, Danielle shows her elegant Rocky Road Meets Neapolitan sundae in a wine glass, with toasted almonds, honey-and cinnamon-roasted strawberries, and a meringue on top.
