HOW TO INCREASE A 15.25 OZ CAKE MIX TO 18.25 OZ. Either buy an extra box of cake mix or make your own. Super-Coupon Queen Jill Cataldo said, the formula for Three-Ounce Cake Mix “Upsizer” goes as follows: Whisk together 1 1/2 cups all-purpose flour, 1 cup sugar, 2 teaspoons baking powder and 1/4 teaspoon baking soda. “Store in a clean mason jar. When you wish to increase a 15.25 ounce cake mix to 18.25 ounces, add three ounces of this mix (6 tablespoons) to your existing cake mix.” Hi! I am the submitter of this (technique) recipe. I know using a box cake really isn't a recipe, but Allrecipes contacted me asking me to submit this because of the requests they received. So with that said, I submitted this so everyone can use my technique and have fun. You can use a box cake or a cake from scratch. I used Wilton (No Taste) RED concentrated paste icing color, and added a few drops of raspberry candy oil to the pink batter for flavor. You can add any flavor candy oil or extract. Someone asked how to get the swirled look on the frosting. Here is how it's done: Paint a vertical stripe maybe 5" or so on the inside of a pastry bag, using a gel or paste tint. Starting at the tip end, you can paint one stripe, two stripes (side by side or one stripe on each side of the bag), or use different colors and paint a bunch of stripes. Just depends on the look you want. Then add your frosting, and swirl it on the cupcake. I hope that made sense.
