Creating Baked Matcha Earl Grey Donuts with Fruity Pebbles is quite simple if you follow these steps:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C) and greasing a donut pan.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, sugar, baking powder, baking soda, salt, matcha powder, and Earl Grey tea leaves until well combined.
3. Combine Wet Ingredients: In another bowl, mix the buttermilk, vegetable oil, egg, and vanilla extract until smooth.
4. Combine Mixtures: Gradually add the wet mixture to the dry ingredients. Stir until just combined; be careful not to over-mix.
5. Fill the Pan: Using a piping bag or a spoon, fill each donut cavity about halfway. Bake for 12-15 minutes or until a toothpick inserted in the center comes out clean.
6. Cool and Decorate: Allow the donuts to cool in the pan for 10 minutes. Then, carefully transfer them to a wire rack. If using glaze, dip the tops into the glaze and sprinkle with Fruity Pebbles for a fun finish!

This straightforward recipe allows you to create charming donuts that are as creative as they are tasty.
