Common Questions
You can use a store bought hazelnut spread, or I really encourage you to try my homemade version . It’s sensational!
Yes, you can certainly opt for vegan chocolate and either omit the egg or use a flax egg instead.
It’s done once the middle has totally set and does not jiggle.
Yes, you can certainly double or even triple this Chocolate Oatmeal Cake recipe. Use a larger baking dish and adjust the baking time if necessary. Ensure the batter is evenly spread out in the dish.
When using baking powder, always check the expiration date. Expired baking powder will not help your recipe rise in the oven, and you’ll have a sad, deflated cake.
While 1 cup of flour weighs 160g in my kitchen, it might weigh anywhere from 120 to 180g in your kitchen and there’s a few reasons for that. The weight of ingredients may vary due to the brand of ingredients, the brand and style (wet vs dry) of measuring cups and spoons, and the technique for measuring into cups: scooping and leveling versus spooning the ingredients into the cup measure. For best results, go by the weight listed in the recipe.
