Step-by-step instructions
Now that you have your ingredients ready, let’s get to the fun part—baking! Follow these straightforward steps for success:
- Preheat your oven to 350°F (175°C) and line a muffin tin with cupcake liners.
- In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt. This ensures an even distribution of dry ingredients.
- In a larger mixing bowl, cream together the softened butter and sugar until it’s light and fluffy. This usually takes about 3-5 minutes.
- Add the eggs one at a time, incorporating them fully before adding the vanilla extract.
- Alternately add the dry mixture and buttermilk, starting and ending with the dry ingredients. Once combined, stir in the boiling water until the batter is smooth and well-blended.
- Fill the cupcake liners about halfway with batter. Add a teaspoon of raspberry preserves to the center, then top with more batter until each liner is about 3/4 full.
- Bake for 18-22 minutes, or until a toothpick inserted into the edge comes out clean. Keep an eye on them to avoid overbaking!
- For the buttercream, beat the softened butter until creamy, then gradually incorporate the powdered sugar. Mix in raspberry puree, vanilla extract, and a pinch of salt until smooth and fluffy.
- Once cupcakes have cooled completely, frost them with the raspberry buttercream and garnish with fresh raspberries and dark chocolate shavings for that perfect finishing touch.
Best ways to enjoy it
Presentation matters! For an elegant touch, consider serving these cupcakes on a beautiful cake stand. A sprinkle of extra raspberry puree on the plate can create a lovely aesthetic, and fresh mint leaves can add a pop of color. Pair with a scoop of vanilla ice cream for an indulgent dessert experience or serve with a hot cup of coffee for a delightful afternoon treat.
Keeping leftovers fresh
If you find yourself with extra cupcakes (or are just planning ahead), storing them correctly is essential. Place them in an airtight container at room temperature for up to two days. For longer storage, keep them in the fridge for about a week. To enjoy them later, reheat gently in the microwave for a few seconds—just enough to warm the chocolate center without drying them out.
Tricks for success
Cooking is as much about the technique as it is about the ingredients. Here are some tips to ensure your cupcakes turn out perfectly every time:
- Room temperature ingredients: This can lead to a smoother batter and, therefore, a tender cake.
- Don’t skip the boiling water: It helps create that perfect molten center by incorporating steam into the batter.
- Monitor your oven: All ovens can vary; start checking at the lower end of the baking time to avoid overbaking.
Creative twists
If you’re feeling creative, there are plenty of variations you can try with this recipe:
- Different fillings: Swap raspberry preserves for other fruit preserves like strawberry or cherry.
- Flavored buttercream: Use lemon or almond extract in the buttercream to add unique flavors.
- Gluten-free option: Substitute regular flour with a 1:1 gluten-free flour blend if you need to accommodate dietary restrictions.
