Preheat oven to 350ºF. Put the flour, salt and baking powder in a medium bowl and stir lightly with a fork. Set aside.
Pulse the sugar and thyme leaves in a food processor, then pour into a large mixing bowl.
Add the lemon zest, olive oil and eggs to the bowl. Using a hand mixer at medium-high, beat for three minutes. The mixture will become uniform and smooth and a lighter yellow.
On low, mix in the milk. Then add the lemon juice, lemon extract and vanilla extract, and mix them in on low.
Add in the flour mixture, a third at a time, and mix just until everything is blended.
Pour and scrape the batter into an oiled bundt pan (don’t oil the pan until just before you fill it!). Put the pan in the center of the oven.
Set a timer for 45 minutes, but this may take a bit longer. The cake is ready when a tester comes out clean and the edges are slightly pulling away from the sides. Note that at this point the top of the cake may not be golden. but when you invert it out of the pan, the rest of the cake will be the perfect golden color.
Cool the pan on a rack for 10 or 15 minutes, then gently loosen the sides with a knife and invert the cake onto a plate. Let it cool entirely.
If you like, garnish with powdered sugar. This is nice served with fresh raspberries or sliced strawberries, or a bit of vanilla ice cream, and it is totally delightful all on its own.
