Add your chocolate, peanut butter and coconut oil in to a large microwave safe bowl and heat in the microwave until everything is melted. This took about a minute in my microwave.
Remove the bowl from the microwave and stir everything together until it's nice and smooth.
Gently fold in your pretzel pieces.
Line and 8x8 inch baking dish with parchment paper. Cut the paper a bit bigger than your dish so it will come up the sides. This will make for easier removal from your pan later.
Gently press your mixture in to the parchment lined baking dish.
Melt the 1/4 cup additional peanut butter in microwave to melt it so you can drizzle over the top of the bites.
While your peanut butter is in the microwave, sprinkle your pretzel pieces over the top of your bites in the baking dish.
Give your melted peanut butter a good stir. It should have a more liquid-like consistency. If it's too thick, you can stream in a bit of melted coconut oil. Drizzle it over your bites.
Cover your pan tightly so the cover doesn't touch the top of your bites, and refrigerate for at least two hours.
When you're ready to cut them, use the parchment paper to gently lift the bites out of the dish. I put mine on to a cutting board, then cut them in to your desired size.
Store these in the refrigerator. You can take one out about 30 minutes before you want to eat it for a softer texture, or eat them cold right out of the refrigerator.
