Creating Battenberg Cupcakes is a rewarding process. Here’s how to do it step-by-step:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and line a cupcake tin with paper liners.
2. Cream Butter and Sugar: In a large mixing bowl, beat the softened butter and granulated sugar until light and fluffy.
3. Incorporate Eggs: Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
4. Mix Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking powder, and salt.
5. Combine Mixtures: Gradually add the dry ingredients to the wet mixture, alternating with milk. Mix until smooth and fully incorporated.
6. Divide the Batter: Split the batter in half. Add cocoa powder to one half, mixing until well combined.
7. Fill the Cups: Spoon the vanilla batter into half of the cupcake liners and the chocolate batter into the other half.
8. Bake: Place the cupcake tray in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
9. Cool: Allow cupcakes to cool in the tin for 10 minutes before transferring them to a wire rack to cool completely.
10. Prepare the Marzipan: While the cupcakes are cooling, roll out the marzipan on a lightly dusted surface. Divide it into two portions and color one half with food coloring to your preference.
11. Assemble the Cupcakes: Cut the cooled cupcakes in half lengthwise, and place a piece of vanilla cupcake next to a piece of chocolate cupcake. Gently press them together.
12. Wrap in Marzipan: Cut the marzipan to fit around each cupcake and gently press it into place, sealing the edges.
13. Dust with Icing Sugar: Finally, dust the top of each cupcake with icing sugar, and add decorations or edible glitter if desired.

These steps will result in beautiful Battenberg Cupcakes that taste as good as they look!
