In a large mixing bowl, combine rolled oats, ground flaxseed, and a pinch of salt. Stir to combine evenly.
In a small saucepan over low heat, melt almond butter and honey (or maple syrup) together until smooth. Remove from heat and stir in vanilla extract.
Pour the melted mixture over the dry ingredients in the mixing bowl and mix well until everything is coated.
Fold in the dark chocolate chips and chopped almonds. Ensure the mixture is evenly mixed and sticky.
Line an 8x8 inch baking dish with parchment paper, leaving some overhang for easy removal. Transfer the mixture to the dish and press down firmly with a spatula or your hands until evenly spread.
Place the dish in the refrigerator for at least 30 minutes to allow the bars to set.
Once set, lift the mixture out of the dish using the parchment overhang and cut into bars of desired size.
Notes
Stack the bars neatly on a wooden board and sprinkle a few chopped almonds and chocolate chips on top for a visually appealing touch. Store extras in an airtight container for a quick snack on the go!
