I took my regular (ie non gluten-free) Kahula Chocolate Cake recipe and adapted it into this for Easter. It turned out great and Gluten-free! Regular cake mix boxes are a little larger, 18 oz instead of the 15 oz that the GF ones come in so you'll need a little extra GF flour to round this out and make sure it's not too goopy.
This was done in 50 minutes using my silicone bundt pan.
Gluten Free Vanilla Rum Cake
Veg oil spray for misting plan
Gluten-free flour for dusting pan
1 pkg (15 oz) Betty Crocker Gluten Free Yellow Cake Mix
1/3 cup gluten-free flour blend
1 pkg (3.9 oz) vanilla instant pudding mix
1 cup sour cream
8 tablespoons (1 stick) butter, melted
½ cup veg. oil
4 large eggs
7 tablespoons Rum
1 teaspoon pure vanilla extract
1 cup butterscotch chips (or white chocolate chips?)
1 tablespoon confections sugar, sifted, as garnish
Place a rack in center of oven and preheat to 350. Lightly mist a 12 cup Bundt pan with veg oil spray, then dust with gluten-free flour, shake out excess flour, set pan aside.
Place the cake mix, gluten-free flour, pudding mix, sour cream, melted butter, oil, eggs, 4 tablespoons of the rum, and vanilla in a large mixing bowl. Blend with an electric mixer on low speed for 1 minute. Stop the machine, scrape down the sides and mix again at a faster speed for about 2 minutes more. The batter should look thick and well combined. Fold in the butterscotch chips, making sure they are well distributed throughout the batter. Pour batter into prepared pan, smoothing it out on top before placing it in the oven.
Bake the cake until it springs back when lightly pressed with your finger and is just starting to pull away from the sides of the pan, 50-60 minutes. Remove the pan from oven and let cool on a wire rack for 20 minutes. Run a long sharp knife around outside edge or the cake and invert onto wire rack.
OPTIONAL: With wooden skewer, poke holes in top of cake, spoon the remaining 3 tablespoons of rum over the cake, letting it seep down into the holes. Let cake cook another 20 minutes.
OPTIONAL: Dust with confection sugar.
Slice & serve.
