If you’ve never baked anything with rice flour before, and you’d like an excuse to make a batch of cupcakes, you’re in the right place! Rice flour, komeko 米粉, is readily available in Japan. There are two different types. The first type is made from mochi rice and called, appropriately, mochiko (もち粉). Another mochi rice version that has an even softer texture is shiratamako 白玉粉. Despite the misleading name that refers to their stickiness, these “glutinous rice” types, are actually gluten-free. They’re used for dense, chewy sweets.
The second type of rice flour, which is defined as “non-glutinous”, and is, also gluten-free, is ground from uruchimai rice (a.k.a. your regular, everyday, Japanese rice). This rice flour might be sold as jōshinko 上新粉 (a finer mill) or jōyōko 上用粉 (the finest mill). It works as a wheat flour substitute.
Today’s recipe for gluten-free cupcakes with blueberry butter cream icing (which might be the best sounding combination that I have ever heard in my life!) comes to us via cookinginjapan.com’s, Kirsten Adachi. A BIG THANK YOU for the recipes, photos, helpful hints, and shopping advice.

Greetings KA International Moms! Thank you so much for letting me submit a recipe.
This month I ran a gluten free feast and I thought I would share a gluten free cupcake recipe. All of the ingredients should be readily available at your local supermarket. You can make this in your food processor, blender or stand mixer, or manually. You can store the cupcakes (iced or not) in a cool room during the day but they should go in the fridge at night during the summer. Both the buttercream and cupcakes can be frozen. I often will freeze half a batch in individual Tupperware cups for cupcake emergencies.
Preheat the oven to 160C. Put all of the dry ingredients in a food processor and give them a quick whir to blend them. Cut the butter into small chunks and add to the dry ingredients. Process until the mixture looks sandy. Add the rest of the ingredients and process until you have a smooth batter. Fill the cupcake/muffin cups half full if you want the cupcakes to be flat at about the level of the top of the cup. Bake for about 15-20 minutes or until a toothpick inserted into the center comes out clean. Take cupcakes out of the oven before they brown. Cooking time widely depends on the oven.
If you don’t have a food processor
Preheat the oven to 160C. Whisk all of the dry ingredients together in a large bowl. Cut the butter into small pieces and add them to the dry ingredients. Use your fingers in a pinching motion to mix the butter and flour mixture. Keep pinching until it looks sandy. In a small bowl, whisk the wet ingredients together. Add the wet ingredients to the dry and whisk until you have a smooth batter. Fill the cupcake/muffin cups half full if you want the cupcakes to be flat at about the level of the top of the cup. Bake for about fifteen minutes or until a toothpick inserted into the center comes out clean. Try not to brown them.
30g unsalted butter at room temperature (無塩バター muenbataa)
1 tablespoon pureed blueberries (I use frozen) ブルーベリー (冷凍) buruuberii (reitou)
125g icing sugar (have extra on hand for adjustments) シュガー パウダー sugaa paudaa
Milk, if needed (any dairy or non-dairy milk will be fine)
Whip the butter with a mixer. Add the blueberry puree and whip until smooth. Slowly add the icing sugar until you have the consistency you want. You may need more icing sugar if your pureed blueberries were juicy or you may need some milk if your blueberries were not so juicy. If you find you need milk to soften the icing, add it a half teaspoon at a time as it goes a long way. You can get icing bag sets at 100 yen shops. Ice the cupcakes in any manner you choose. Buttercream freezes well so you can keep any leftovers.
Note: if you are dairy-free as well, you can replace the butter with coconut oil. I have never tested this but there are many recipes that come up when you search on google.
Where to find the ingredients
Almond meal (アーモンドパウダー aamondo paudaa) – there should be small bags in the baking section of your local supermarket. If not, an import store or an upscale supermarket.
Starches – katakuriko (片栗粉) and cornstarch (コーンスターチ coonsutaachi) are both found easily in supermarkets. Tapioca starch (タピオカ粉 tapiokako) can be found in import stores and on Amazon.
Rice flour (米粉 komeko) can be found in most supermarkets. You can also use “top grade rice flour” (上新粉 joushinko) which every supermarket will have at least a small bag of as it is used for making Japanese sweets.
Unsalted butter (無塩バター muenbataa) should be found in all supermarkets; also labeled 食塩不使用バター shokuenfushiyou
Vanilla essence (バニラエッセンス banira essensu) is in the baking section of all supermarkets.
Blueberries are with frozen foods.
Icing Sugar – (シュガー パウダー sugaa paudaa) there should be small bags (70g) in the baking section of your local supermarket, big bags are available on amazon.
Note: when cooking or baking for someone who is gluten free, make sure to ask how sensitive they are. Some people are okay as long as nothing contains gluten and others need to worry about where the ingredients were processed and cooked. Always ask. If you need to find certified gluten free foods, try A-soken (only in Japanese), Amazon (use gluten free グルテンフリー or non gluten ノングルテン with your search terms) or iherb.com. You can also find some gluten free products at import stores and health food stores.
