Preheat your oven to 350°F and line a 12-cup muffin tin with cupcake liners. I always spray the liners lightly with baking spray because sometimes they stick to the cake even when you don't want them to. This takes literally 60 seconds and saves frustration later.
Whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt in a large bowl. Make sure there are no lumps in the cocoa powder—break them up with the back of a spoon if needed. This dry mixture is the foundation for your red velvet cupcakes family kids will actually request again.
In another bowl, whisk the eggs, then stir in the melted butter, milk, food coloring, vanilla bean paste, and vegetable oil. The batter will look deep red and pretty dramatic—that's exactly what you want. Don't panic if it looks watery at first because it's supposed to be that consistency.
Pour the wet ingredients into the dry ingredients and fold everything together until just combined—don't overmix or your easy family cupcakes will get dense and rubbery. I use a rubber spatula and fold about 8-10 times, then stop. Over-mixing is honestly the #1 mistake people make here.
Fill each cupcake liner about two-thirds full with batter. I use a spring-loaded scoop which makes this go faster and keeps things even. If you don't have one, a regular tablespoon works—just take your time.
Bake for 18 minutes at 350°F until a toothpick inserted in the center comes out with just a few moist crumbs. Mine always bakes right at 17-18 minutes, so check around minute 16 just to be safe. You'll know they're done when the tops spring back when you touch them gently.
Let the cupcakes cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely before frosting. This matters because frost while warm and everything gets melty and weird.
