Easy, Low Calorie, Upside-Down German Chocolate Sheet Cake

There is only two times a year (i.e. Thanksgiving and Christmas) that I make the infamous two- or three-layered German Chocolate Cake in all of its richness and its notable detail in baking and trust me when I say it is a sweet chocolatey treat my family have come to expect and look forward to at the end of every year. However, this past November 2023, I deviated from the norm in making the usual German chocolate cake recipe. Instead, I made Sugar Free German Chocolate Cupcakes where I followed the similar steps involved in making the cake recipe, only modifying some of the ingredients in the process.

Sugar Free German Chocolate Cupcakes, November 2023

Despite using sugar free sweeteners and other low carb flours (almond and oat), the cupcakes were still super delicious without the use of white processed sugar and flour (Note: German Chocolate Cupcake recipe will be posted in the near future). Nevertheless, with the holidays and yet another year having come and gone only a month ago, I felt in the mood to make this special cake once again, however, only a tad bit simpler.

Here are my thoughts about my easy low carb Upside-Down German Chocolate Sheet Cake. What I like about this recipe is that it has that same delicious taste as the regular GC cake, and even better yet that the steps are relatively few. Also, the cake layer itself is super moist. There is a coconut pecan honey crumble that comes together in mere minutes and serves as the topping in place of my normal stovetop coconut, pecan, milk and butter frosting.

The crumble is placed at the base of a buttered or oiled parchment lined sheet pan, while the chocolate batter is poured over it being it’s an upside-down cake. Therefore, some of the coconut and pecans may also nestle into the cake layer a bit, giving it texture and a nice chewy bite.
