Step 1

Preheat the oven to 350°F (177°C) and grease a 10-inch Bundt pan.

Step 2

Whisk the flour, baking powder, and salt together in a large bowl. Set aside. Using a handheld or stand mixer fitted with a whisk attachment (or you can use a whisk) mix the oil, 1 cup granulated sugar, the brown sugar, eggs, and vanilla together until combined. Pour the wet ingredients into the dry ingredients, add the milk, and beat on low-medium speed it all until the batter is completely combined. Batter is thick, yet silky.

Step 3

Mix the remaining sugar, peaches, and cinnamon together in a medium bowl.

Step 4

Pour 1/3 of the cake batter evenly into the prepared Bundt pan. Arrange half of the peaches on top (including any juices!). Pour another 1/3 of cake batter evenly on top, followed by the rest of the peaches. Finally, cover with remaining cake batter. Use a spatula to smooth over any exposed peaches as best you can.

Step 5

Bake for 55-70 minutes or until a toothpick inserted into the cake comes out clean with just a couple lightly moist crumbs. This is a large, heavy cake so don’t be alarmed if it takes a little longer in your oven.

Step 6

Once done, remove from the oven and allow to cool for 2 hours inside the pan. Then, invert the slightly cooled Bundt cake onto a wire rack or serving dish. Allow to cool completely.

Step 7

Slice the butter up into pieces and place in a light-colored skillet. (Light colored helps you determine when the butter begins browning.) Melt the butter over medium heat, stirring occasionally. Once melted, the butter will begin to foam. Keep stirring occasionally. After 5-8 minutes, the butter will begin browning– you’ll notice lightly browned specks begin to form at the bottom of the pan and it will have a nutty aroma. See photo above for a visual. Once browned, remove from heat immediately and allow to cool for 5 minutes. (The butter will eventually solidify, so don’t let it sit too long.) After 5 minutes, whisk in the rest of the icing ingredients until smooth. Add more confectioners’ sugar for a thicker texture, if desired. Likewise, add more milk to thin out if needed.

Step 8

Drizzle icing over cake before slicing and serving.

Step 9

Cover leftover cake tightly and store at room temperature for a couple days and/or in the refrigerator for up to 5 days.
