Lemon Supreme Loaf Cake is a slightly enhanced loaf pan version of Duncan Hines Lemon Pound Cake. It’s a cake mix recipe with few more ingredients to make the texture a little more like scratch. Whether it’s more convenient is subjective. Personally, I do find it more convenient because I always have the extra ingredients on hand. And since there’s no creaming of the butter and sugar, the recipe flies together.
Lemon Supreme Loaf Pan Cake Changes
I’ve made this cake at least 4 or 5 times now, and it’s always good. The cake in the first photo is the prettiest, and I think it’s because I paid close attention to the mixing, using the two-stage method. The other times I just chucked everything into the bowl and mixed. The lazily mixed cakes were still good, but didn’t rise as high and have such a rounded top. Substituting ingredients (such as sour cream for the yogurt and AP for cake flour) also changes the shape, so I recommend using the ingredients listed.
Pineapple Supreme Variation
This recipe also works well with Duncan Hines Pineapple cake mix and vanilla flavored instant pudding. With the pineapple cake mix, it bakes up with a slightly more open crumb, but it still very tasty and goes well with this pineapple glaze. I still prefer the lemon version over the pineapple, but the pineapple was good too.
Enhanced Cake Mix Variations
There are all kinds of variations you could do with this enhanced cake mix recipe. Since I love the flavor of lemon cake mix I mainly use it for lemon, but I’ll update when I try it with vanilla or chocolate. There are so many ways you could change this up by changing cake mix flavors, pudding and maybe even the flavor of the yogurt.
Lemon Supreme Loaf Cake Ingredient Rundown
- Duncan Hines Lemon Supreme Cake Mix — I haven’t tested with other brands. You’ll use half a box. It’s important to weigh the cake mix, but if you need to measure by volume a half box of cake mix is about 1 2/3 cup.
- Jell-O brand instant pudding, lemon flavor — half a box. You can use the other half of the box for another cake or make a half batch of White Chunk Lemon Pudding Cookies.
- Cake Flour — I’ve tested with cake flour and all-purpose. Because cake flour has less protein, you can beat it a little more without strengthening the gluten. In my experience, the cake rose higher when I used cake flour and beat the batter on medium speed for 1 minute. When I used all-purpose flour, I beat only by hand and the cake didn’t rise quite as much.
- Sugar — Regular granulated
- Baking Powder
- Olive Oil — Canola is fine too.
- Butter — Softened to the point it is almost melted.
- Lemon Zest — About a tablespoon, but you can use more or less
- Eggs — Room temperature. I usually just submerge them in warm water to bring to room temperature quickly.
- Whole Milk Greek Yogurt — Tested with sour cream and the cake didn’t rise as high, so I recommend sticking with whole milk Greek yogurt. Also bring to room temperature.
- Water — I accidentally left it out once and the cake didn’t rise as high, so make sure to add the water.
