Tips & Variations
- For the best gooey texture, avoid overbaking; the center should still jiggle slightly when done.
- You can substitute almond butter or cookie butter in place of peanut butter for a different flavor twist.
- Adding a sprinkle of sea salt on top balances the sweetness nicely.
- Use parchment paper to line the baking dish for easier cleanup and to prevent sticking.
Storage
Store any leftover cake in an airtight container at room temperature for up to 2 days or refrigerate for up to 5 days. Reheat individual portions in the microwave for 20–30 seconds to restore warmth and gooey texture. This cake is best enjoyed fresh but will keep well chilled.
