Melt the almond butter, honey, vanilla and cinnamon together in a microwave, or on the stove-top, and mix until thoroughly combined.
In a separate bowl, mix the rice, raisins and flaxseed.
Pour the almond butter mixture over the cereal mixture and mix until all combined well.
Place in a prepared pan (I used a 9" square baking pan lined with parchment paper) and push down on the mixture either with a spoon or your hands to make sure it is as compact as possible.
Chill in the refrigerator or freeze until hard.
Cut into bars (rectangle or square) depending on how many you wish to make.
Store in either the refrigerator or freezer, depending on your personal preference.
