In a saucepan, heat the maple syrup on medium-high until it begins to bubble.
Remove from heat and whisk in the cashew butter.
Pour in the oat flour. Mix until combined.
Let the dough chill completely, then mix in any add-ins - If you do not let the dough chill, your add-ins could melt!
To form, press the chilled dough into a lined loaf pan. Carefully remove the dough (so that it keeps its shape) and flip it over (so the rounded corners face up). Using a knife, cut the dough into 18-32 pieces, keeping them pressed together at the sides. Freeze again.
Once frozen, you will be able to break off a piece every time you need a treat!
