Method: Preheat the oven to 175°C. Give it a go and let me know what you think! 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. 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. This recipe makes enough for 12 cupcakes or one 8 inch round cake layer. Line a 6 or 12 hole muffin pan with muffin cases, and set aside. 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. So I thought about it and created this original recipe and made super fluffy and tall matcha mochi butter muffins with beautiful high tops! Add eggs one at a time and beat after adding each egg, beat until light and fluffy. Sift together glutinous rice flour, matcha powder and baking powder. Step 1. In a large mixing bowl, cream together butter and light brown sugar.
