Line a 9x9-inch pan with parchment paper. Leave an overhang for easy removal of bars.
Add sliced almonds and pumpkin seeds to a food processor. Pulse for about 7–10 seconds (on chop setting), until the nuts are broken up. Add to a large bowl. With a sharp knife, coarsely chop the dried tart cherries (they don’t chop well in the food processor). Place in the bowl with the nuts. Add in the quick oats and salt. Stir together.
In another bowl, add creamy almond butter and honey. Microwave for 30 seconds. Remove and pour in the vanilla extract. Stir for about 30 seconds to 1 minute or until well blended.
Pour the wet ingredients into the dry ingredients. Use a hand mixer (or your hands) to mix/knead the mixture together until combined. This takes a little effort, but it will come together. Once the ingredients are well combined, pour into the prepared pan and press firmly into place with your hands. Use the bottom of a 1 cup measuring cup to really pack the mixture together in an even layer. Press firmly to avoid crumbling later.
Coarsely chop a dark chocolate bar and place it in a small microwave-safe bowl. Microwave for 15 seconds, stir for 15 seconds, and if needed, return to the microwave and repeat for another heat/stir cycle until smooth and melted. Using a spatula, transfer the melted chocolate to a small bag and snip off the corner (or use a piping bag fitted with a #3 tip). Drizzle chocolate over the bars.
Refrigerate the pan for 30 minutes to an hour or until chocolate is hardened and the bars are firm. When you’re ready to slice, lift the bars out of the pan by using the parchment overhang. Use a sharp knife to cut into 16 bars (7 vertical cuts and 1 horizontal cut down the middle).
