First, combine all of the ingredients in the saucepan over medium heat, stir just enough to mix everything. Then, increase the heat to medium-high and cook the mixture, without stirring, until it reaches a deep golden color.
Bring the caramel mixture to a boil. If you have a candy thermometer, the temperature of the caramel should reach 235-245°F.
Then, reduce the heat to low and let the mixture simmer for 5 minutes while stirring with a silicone spatula.
Finally, let the caramel glaze cool slightly in the pan, then transfer the glaze into a glass jar to finish cooling.Remember to let the glaze (and the bundt cake) cool completely before pouring the glaze on top of the cake.
Bundt cake
First, preheat the oven to 350°F and measure out all of the cake ingredients.
Next, in a large mixing bowl, drop in the sugar and the softened butter.
Beat the butter and sugar together with a hand mixer on medium speed until the mixture is light and pale in color.
Then, in a separate small bowl, whisk the 3 eggs together.
Next, pour the vanilla extract, beaten eggs, and yogurt into the butter and sugar mixture, use the hand mixer to completely mix all of the wet ingredients together.
In another medium-sized bowl, pour in the flour, baking soda, and salt.
Combine the dry ingredients with a blending whisk.
Then, add the flour mixture into the wet ingredient mixture, ½ at a time, mixing well between each addition.
Continue to mix the cake batter until all of the wet and dry ingredients are completely combined.
Next, add the chopped apples and the ½ cup almond slivers into the bowl of cake batter.
Use a spatula to gently fold the apples and almond slivers into the cake batter until evenly mixed in.
Bundt cake pan coating
First, grab everything you need for coating the bundt cake pan: some food-friendly disposable gloves, vegetable shortening, flour, and a sifter.
Then, use gloved hands to coat the entire inside of the bundt cake pan with the vegetable shortening. Make sure to get all the sides and corners.
Afterward, use the sifter to evenly sprinkle a light coating of flour over the layer of shortening.
Then, turn the cake pan over and dump out any excess flour.
Evenly distribute the apple cake batter into the greased bundt cake pan and spread it evenly with a spatula.
Bake the bundt cake for 50-60 minutes, or until a toothpick inserted in the middle comes out clean. Then, let the cake cool for a minimum of 30 minutes before removing it from the pan. If you do not let the cake cool long enough, it will come out of the pan in parts.
Finally, after resting in the pan, remove the apple cake from the pan and flip it onto a cooling rack to finish cooling completely, about 1-2 hours, before drizzling with the glaze.
Bundt cake decoration
First, slide a sheet of parchment paper under the wire rack of the completely cooled bundt cake. Then, slowly pour the cooled caramel glaze over the entire bundt cake.
Finally, use the remaining almond slivers to decorate the top of the bundt cake immediately after drizzling with the glaze.
