Cake – How to “fill” a cake made from a cupcake recipe

cakecupcakesfilling

I have several cupcake recipes. I know it's easy to convert to a cake (just adjust baking time and figure out correct pan size). My question is many of the cupcake recipes have a filling that is (for the most part) just sort of stabbed into the baked cupcake using a squeeze bottle. These fillings are usually between artificial maple syrup and pudding in consistency/thickness. If I want to use the filling, how would I incorporate it into the cake other than repeatedly "stabbing" the cake in various places? A google search only tells me to tort the cake, but I'd like to leave it in a single layer if possible (plus I don't think the cupcake fillings would hold up to be filling layer in a layered cake).

A syringe (or baster, but a syringe will be better) A LOT of holes, and frosting to hide the holes (though they will be pretty small if you use a syringe.)

Given the comment that "I don't want it to be like several filled donuts joined together where it's not consistent" in combination with a refusal to consider layering it, you need

  1. a dense pattern of holes and
  2. a measured amount of filling in each hole.

So, for a 9x13 pan, you might be looking at 8x12 = 96 holes an inch apart, starting 1/2 inch from the edge, each filled with 1/96th of your total amount of filling. Adjust as needed for other size cakes and how well an inch apart suits your idea of "consistent" - you could go to 17x25 holes 1/2 inch apart and 1/4 inch from the edge, but it's going to be rather tedious.

Or you could TRY a more cake-centric approach - half the batter, the filling, half the batter, bake. It might fail miserably, it might "work" for some value of "work," it might require changing the filling to get a better value of "work." Certainly marble cakes and pudding cakes do things of this nature at the batter stage before baking.
