Instructions
- Preheat oven to 350°F (180°C). Line an 8-inch cake pan with parchment and oil the sides.
- Whisk flour, cocoa, baking powder, baking soda, and salt.
- In a large bowl, whisk sugar, oil, egg, vanilla, and milk. Stir in dry ingredients, then hot coffee. Pour into pan and bake 20–30 minutes until set. Cool completely.
- Whip peanut butter, powdered sugar, and granulated sugar until fluffy. Add cream and vanilla, then whip until light and airy.
- Place cake in a tart or springform pan. Spread mousse evenly. Freeze 4–6 hours until firm.
- Melt chocolate and oil until smooth. Pour over frozen cake on a rack, coating sides. Chill 10–15 minutes. Flip right side up, spread more ganache, and top with salt and peanut butter cups. Freeze 30 minutes more.
- Slice with a hot knife and serve chilled.
Notes
- Swap Reese’s for Snickers or KitKats.
- Use milk chocolate for a sweeter ganache.
- Add crushed Oreos between cake and mousse.
- Make minis in muffin tins for individual servings.
- Add caramel sauce to mousse for extra indulgence.
