Tips & Variations
- For a richer peanut butter flavor, stir a few tablespoons of peanut butter directly into the chocolate batter before baking.
- You can substitute regular cream cheese with a lighter version to reduce calories without sacrificing too much creaminess.
- If you prefer a gluten-free option, use gluten-free cake and brownie mixes.
- Allow the ganache to set slightly before serving for a thicker, fudgier topping.
Storage
Store the cake covered at room temperature for up to 2 days or in the refrigerator for up to 5 days. To reheat, let slices come to room temperature or warm gently in the microwave for 10-15 seconds. The ganache and peanut butter garnish may firm up when chilled but will soften when warmed.
