MELTED CANDLE CUPCAKES 🖤🕯give me a few cupcakes, s MELTED CANDLE CUPCAKES 🖤🕯give me a few cupcakes, some dye-free black buttercream, and black chocolate ganache and watch me transform them into the spookiest edible centerpiece! 

Full tutorial is linked in my bio + at https://sugarandsparrow.com/melting-candle-cupcakes/ but I have a condensed version below: 
 
SUPPLIES: ⁣ 
-9 cupcakes⁣  (made these with my small batch black velvet cake recipe!) 
-1 batch of dye-free black buttercream 
-boba straws or skewers (for stabilizing the taller candles) ⁣ 
-icing smoother + turntable ⁣ 
-black ganache for dripping⁣ 
-3 birthday cake candles⁣ 
-matches ⁣ to light them
⁣ 
INSTRUCTIONS: ⁣ 
1. Fill and stack the cupcakes: one stack of 2 cupcakes, one stack of 3 cupcakes, and one stack of 4 cupcakes. For the two taller cupcakes I inserted a boba straw through the middle to stabilize the stack for frosting. ⁣ 
2. Frost the stacked cupcakes with smooth buttercream and keep the top edge raw. Refrigerate for 20 minutes to let the frosting firm up. ⁣ 
3. Transfer the frosted cupcake candles  onto a small plate and pipe ganache around the edges and tops to look like melted wax. ⁣ 
4. Insert a birthday cake candle into each cake candle (keep the wick about 1/4 inch from the cake surface) and light! ⁣

DYE-FREE BLACK VELVET CUPCAKES 🖤 These all black c DYE-FREE BLACK VELVET CUPCAKES 🖤 These all black cupcakes use black cocoa powder (and NO food coloring!) to achieve that rich black color for the cupcakes + black buttercream. That means they won’t turn anyone’s mouth black AND they taste like Oreo cookies in deliciously moist cupcake form 👻

✨Full recipe (with dye-free black buttercream) is linked in my bio + at https://sugarandsparrow.com/black-velvet-cupcakes/ 

BLACK VELVET CUPCAKES
Yield: 14 cupcakes

1 Cup (132g) all purpose flour
3/4 Cup (150g) granulated sugar
1/3 Cup (38g) black cocoa powder
1 tsp baking soda
1/2 tsp baking powder
1/4 tsp salt
1/4 Cup (60ml) vegetable oil
1 large egg, room temperature
1/2 tsp pure vanilla extract
1/2 Cup (120ml) full-fat buttermilk*
1/2 Cup (120ml) hot coffee or hot water

INSTRUCTIONS:
1. Preheat the oven to 350°F (177°C). Line a muffin pan with cupcake liners and set aside.
2. Place all of the dry ingredients into a large bowl and whisk together to combine. Add the vegetable oil, eggs, vanilla, and buttermilk and whisk until combined. With the mixer still on low, add the hot coffee (or hot water) and whisk until smooth, about 2 minutes. The batter will be very thin. 
3. Pour the batter into the prepared cupcake liners (no more than ⅔ full) and bake for 15-18 minutes, until a toothpick inserted comes out with just a few moist crumbs on it. Cool completely before frosting with dye-free black buttercream (full recipe linked in my bio).

*If you don’t have buttermilk on hand (I rarely do!), use 1/2 Cup whole milk mixed with 1 1/2 tsp vinegar or lemon juice.

EASY MUMMY CUPCAKES 👀 this classic Halloween cupca EASY MUMMY CUPCAKES 👀 this classic Halloween cupcake design is so easy to make with chocolate cupcakes, googly eye sprinkles, vanilla buttercream, and one piping tip! Here’s how:

Full tutorial (with recipes for the cupcakes and buttercream!) is linked in my bio + at https://sugarandsparrow.com/mummy-cupcakes/

MUMMY CUPCAKES SUPPLIES: 
-Baked chocolate cupcakes
-Vanilla buttercream
-Googly eye sprinkles
-Piping bag
-Small flat piping tip or basket weave tip

INSTRUCTIONS: 
1. Press two googly eye sprinkles on top of the chocolate cupcake.
2. Starting on the edge of the cupcake, pipe a straight line to the opposite edge, avoiding the googly eye sprinkles. If you’re using a basket weave tip, make sure the grooved edge is face down.
3. Continue piping lines that connect the edges, overlapping the lines until the surface of the cupcake is covered (aside from the googly eyes) and the piping looks like mummy cloths.
