Line a baking pan (mine measures 7x11) with parchment paper and leave about a 2-inch overhang on both sides. Grease the paper with a little bit of oil.
Melt wet ingredients in a pan (on low heat), or in a double boiler or in the microwave for max. 1 minute.
Add all dry ingredients to a big bowl, stir until combined. Pour wet ingredients into the bowl of dry ingredients and mix until everything is evenly distributed.
Transfer the mixture to your lined baking pan, spread it evenly with your hands, and press it down as firmly and evenly as possible.
Place the pan now in your freezer (cover it with plastic wrap) and leave it there for at least one hour until set.
Remove the pan from the freezer and easily lift the mixture out of the pan like shown in the following photo. Use a sharp knife to cut the mixture into squares or rectangles.
Store the no-bake granola bars in the fridge or in the freezer (wrapped in freezer bags) for best results. If you want to take your bars with you (snack on the go) I would recommend wrapping them individually in plastic wrap, so that they hold their shape.
