🍽 Ingredients

📖 Instructions

  1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour your prism mold meticulously. Trust me; you don't want this to stick!
  2. Combine Dry Ingredients: In a large mixing bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking soda, baking powder, and salt. Make sure there are no lumps!
  3. Cream Butter and Sugar: In a separate bowl, using a stand mixer (or a hand mixer), cream together the unsalted butter and granulated sugar until light and fluffy. This usually takes about 3-5 minutes. It's gotta be *really* fluffy!
  4. Add Eggs and Vanilla: Beat in the eggs one at a time, then stir in the vanilla extract. Scrape down the sides of the bowl to ensure everything is well combined. We don't want any eggy surprises!
  5. Incorporate Wet and Dry Ingredients: In a small bowl, mix the buttermilk and red gel food coloring. Gradually add the wet ingredients to the dry ingredients, alternating with the buttermilk mixture, beginning and ending with the dry ingredients. Mix until just combined. Don't overmix!
  6. Add Vinegar and Baking Soda: In a small bowl, combine the white vinegar and baking soda. It will fizz! Add this to the batter and mix until just combined. This step is crucial for that signature red velvet tang!
  7. Pour into Mold: Pour the batter into the prepared prism mold, spreading it evenly. Tap the mold gently on the counter to release any air bubbles. Those pesky bubbles!
  8. Bake: Bake for 30-40 minutes, or until a cake tester inserted into the center comes out clean. Keep an eye on it; ovens vary!
  9. Cool: Let the cake cool in the mold for 10-15 minutes before inverting it onto a wire rack to cool completely. Patience is key!
  10. Prepare the Chocolate Ganache: Place the chopped dark chocolate in a heatproof bowl. In a saucepan, heat the heavy cream over medium heat until it just begins to simmer. Pour the hot cream over the chocolate and let it sit for a minute to melt the chocolate.
  11. Stir Ganache: Gently stir the chocolate and cream together until smooth and glossy. If the chocolate doesn't melt completely, you can heat the mixture in 30-second intervals in the microwave, stirring in between, until smooth.
  12. Cool Ganache: Let the ganache cool slightly until it thickens to a spreadable consistency. This might take about 30 minutes. Don't rush it!
  13. Frost the Cake: Once the cake is completely cool and the ganache has thickened, use an offset spatula to spread the ganache evenly over the top and sides of the prism cake. Make sure to cover every nook and cranny!
  14. Chill (Optional): For a cleaner finish, you can chill the frosted cake in the refrigerator for about 30 minutes to set the ganache.
  15. Decorate: Decorate the cake as desired. You can use fresh berries, chocolate shavings, or a dusting of cocoa powder. Get creative!
  16. Slice and Serve: Slice the Red Velvet Prism Cake carefully and serve. Enjoy every bite!
