Keep Refrigerated

Magic Monster Layer Bars are perfect for your next potluck or holiday dessert. You can make them days ahead of time and they’ll still be gooey and chewy. Make sure you refrigerate them before bringing them to your next summer BBQ to prevent them from getting too sticky or melting.  They are a crowd pleaser, and you won’t be able to leave your next event without someone asking you for the recipe.

To make these bars even more amazing, try serving them with Homemade Vanilla Ice Cream or Homemade Whipped Cream.


Pantry Friendly

These Magic Monster Layer bars are the ultimate pantry recipe, and you can swap out or add in other ingredients that you find in your kitchen, meaning that they won’t require you to make an extra trip to the store. If you don’t have sweetened condensed milk on hand, you can make it easily yourself with milk, sugar and vanilla extract. Making sweetened condensed milk takes about an hour, so make sure you leave enough time.

Homemade Sweetened Condensed Milk

  • 3/4 cup granulated sugar
  • 1/2 teaspoon vanilla extract
  1. In a medium saucepan, whisk the sugar and milk until combined.
  2. bring the milk mixture to a low simmer over medium heat, whisking often.
  3. Turn down to low heat and simmer until mixture has reduced by half.
  4. Once reduced, remove from heat and stir in the vanilla extract.
  5. Cool completely before storing in a glass jar and refrigerate for up to 2 weeks.

Note: You can use any non-dairy milk (like almond milk!) for vegan Sweetened Condensed Milk.
