Step 1. Method: Preheat the oven to 175°C. Give it a go and let me know what you think! Sift together glutinous rice flour, matcha powder and baking powder. When I searched for mochi butter muffin or mochi butter cupcake recipes online, it surprised me to see flat-topped and short mochi butter muffins or cupcakes, that also looked super-dense. Line a 6 or 12 hole muffin pan with muffin cases, and set aside. Add eggs one at a time and beat after adding each egg, beat until light and fluffy. So I thought about it and created this original recipe and made super fluffy and tall matcha mochi butter muffins with beautiful high tops! This recipe makes enough for 12 cupcakes or one 8 inch round cake layer. EDIT 09/2020: My husband thought the cake was too dense for him, so I made it again with only 1 cup cake flour and it resulted in a spongier texture, which he preferred.If you like dense American cakes, leave the recipe as is. In a large mixing bowl, cream together butter and light brown sugar. Gather dry ingredients (glutinous flour, brown sugar, baking powder, matcha powder or cacao powder) in a bowl before measuring out the wet ingredients (egg, milk, olive oil) in another bigger bowl. Preheat oven to 400°F.
