Hostess Cakes Sheet Cake

Ingredients:

Directions:

1. Preheat the oven to 350 degrees F. Grease a metal 9x13 baking pan and line with parchment paper.
2. Add the melted butter, sugar, vegetable oil, and vanilla extract to the bowl of a stand mixer. Mix until starting to combine, then add the eggs with the mixer on low speed and mix until well combined.
3. Add the cocoa powder, flour, baking soda, baking powder, and salt to a separate bowl and whisk to combine. Add ½ of the dry ingredients plus the milk to the stand mixer and mix until starting to combine. Add the other ½ of the dry ingredients plus the coffee and mix until well combined.
4. Pour into the baking pan and bake for 30-34 minutes or until baked through. A toothpick inserted in the middle should come out clean. Remove from the oven and let cool on the counter until completely cool. Cover and refrigerate for at least one hour or up to overnight.
5. Lift the cake out of the baking pan and place on a serving platter. Use a long bread knife to slice the cake in half, lengthwise. Carefully remove the top layer and set aside.
6. Make the filling. Add the butter and marshmallow fluff to the bowl of a stand mixer and beat until smooth. Add the vanilla extract, powdered sugar, salt, and milk and mix until well combined.
7. Add the filling to the bottom half of the cake, reserving about ½ cup for decoration. Spread evenly across the top and all the way to the sides. Place the top half of the cake on top of the filling layer and refrigerate for at least 30 minutes.
8. Make the frosting. Add the butter, powdered sugar, and cocoa powder to the bowl of a stand mixer. Mix until well combined. Add the vanilla extract, milk, and salt and mix until well combined and smooth. Add additional milk to thin out the frosting if you think it’s too thick.
9. Add the frosting to the top of the cake and spread evenly across the top and down the sides.
10. Add the leftover filling to a piping bag or Ziploc bag and snip of a tiny piece. Pipe a swirly pattern on top of the cake in rows to resemble the Hostess Cakes design.
11. Slice, serve and enjoy!
12. Leftovers ca be stored at room temperature or in the fridge. Keep sealed in an airtight container or cover with plastic wrap.
