Mixpeanut butter, honey, vanilla, oats, chopped dates, pumpkin seeds and almonds in a large bowl.
Stir the 2 tbsp of peanut butter and yogurt in a separate bowl until smooth and creamy.
Press the bar mixture into a 9×9inch pan lined with parchment paper (9×13 will work – it will just yield wider, flatter bars). Pour the yogurt mixture evenly. Freeze for 30 minutes. Pull out of the pan and cut into bars.
