These treats are so amazingly good that we’re making them for the third time this week!

Refrigerate for at least 1 hour, or until set.
Cut into squares and serve.
Variations and tips
For a nut-free version, swap out the peanut butter for sunflower seed butter. You can also add a handful of chopped nuts or dried fruit for added texture and flavor. If you prefer a touch of chocolate, try using chocolate chips instead of toffee bits, or drizzle melted chocolate on top before refrigerating. To make the squares more festive, consider adding colorful sprinkles or edible glitter to the top before they set.
