Preheat your oven to 350°F (175°C). This initial step is essential. It ensures that your cupcakes start baking at the right temperature.
In a large mixing bowl, combine Pamela's Pancake and Baking Mix, cocoa powder, and salt. Stir until well combined. Mixing these ingredients first helps distribute the cocoa evenly, ensuring that every bite is chocolatey.
In a separate bowl, beat the eggs with the granulated sugar until the mixture becomes pale and frothy. This can take about 2-3 minutes. It’s crucial to incorporate air into this mix to achieve a fluffy texture.
To the egg-sugar mixture, add the vegetable oil, vanilla extract, buttermilk, and sour cream. If you’re opting for the espresso powder, add it here as well. Stir until just combined. The buttermilk curdles slightly with the vinegar, creating a delightful fluffiness.
Slowly fold the dry mixture into the wet mixture. Be gentle! You want to avoid over-mixing. Stop as soon as you see no dry ingredients.
Now’s the fun part—add the red food coloring. A little goes a long way! Combine until you achieve a beautiful, rich red hue throughout the batter.
Fill your cupcake liners about two-thirds full with the batter. Bake in the preheated oven for approximately 20-25 minutes. The cupcakes should spring back when gently pressed. Allow them to cool completely on a rack.
Once cooled, frost them with your favorite gluten-free frosting. You can use a simple whipped cream, a vegan option, or something more decadent based on your mood.
