Pre-heat your oven to 350℉ and line your baking sheets with parchment paper.
In a large bowl add your peanut butter and softened butter and cream together.
Add your brown sugar, sugar and stir together until light and fluffy.
Add your eggs and vanilla and mix again.
Once, everything is well combined, add your dry ingredients. Flour, baking soda, cornstarch and salt. Stir until just combined.
Stir together your heavy whipping cream and remaining peanut butter together and add dollops into your peanut butter cookie dough. Do the same with your jelly.
Scoop your cookie dough with a 1-2 inch cookie scoop and then place on your baking sheets lined with parchment paper, a few inches apart.
Bake in your oven at 350 for 8-10 minutes until they start to set and brown.
Remove from oven and using a round cookie cutter, scoot the edges of your cookies to make them perfectly round. (optional)
Top each cookie with some peanut butter & jelly if desired and a sprinkle of flaky sea salt.
