Some things are best when you don't over-think.
Waffles are definitely that. There are fancier recipes, but none faster - and likely to make you happy every time.
Use this amount for two adults and 1 or 2 small kids. For bigger kids, or more people, double it.
1 C flour
1.5 Tbs sugar
1/2 tsp baking powder
1/2 tsp salt
2 Tbs butter
1 C milk
cereal sized bowl
measuring cups and spoons
1/4 cup measure
small bowl for melting butter
vegetable oil and brush - or spray to oil the waffle iron
Melt the butter in the microwave in a very small microwave safe bowl. Set aside to cool to the touch, but not harden.
Measure out all the dry ingredients (flour, sugar, baking powder, salt) into the medium bowl. Use the fork to quickly stir them together.
Turn on the waffle iron to medium. Oil the plates.
While the waffle iron is heating, break the egg into the cereal bowl, and beat with the fork. Add about half the milk and stir them together. Add the butter, stir that in too. Dump these liquids into the dry ingredients, stir about 5 times with the fork. Add some or all of the rest of the milk to make a pourable and slightly lumpy batter (about 10 more stirs - no more!).
Use the 1/4 cup measure to pour batter into the center of the heated, oiled waffle iron.
Check the result of the first one when your indicator says "Done!"
Use a little more or less batter, and possibly adjust the temperature setting to get what you want.
Blueberry Waffles - Add the batter as usual, but just before closing the lid, scatter a handful or two of berries over the batter. Fresh or frozen are fine. Raspberries and Blackberries work too. Very large berries benefit from being cut in half.
Ham Waffles - Super "breakfast for dinner" fodder. Cut about 1 C of cubes from thickly sliced ham. (Ask for 2-3 1/4" thick pieces at the deli counter). Sprinkle them in the same way blueberries are sprinkled in. Bacon is also acceptable.
