When I break blocks they just reappear?

Question

I try to break blocks in single player but it just lags out and when I do, it breaks and then it reappears. I keep breaking it and then it eventually falls. I want it to stop.

P.S. It doesn't do this in Minecraft multiplayer.

It's weird that this only happens on single player, try these to see if they solve your problem
Change video settings.

If your Render Distance is high and your computer is trying to load a mass amount of chunks then this could cause your PC to lag.  You can also turn Particles to low, Graphics to fast, and Clouds off.
Turn VBO's on

If you look in the Minecraft menu under Options then Video Settings  You should see Use VBO's this is supposed to increase your FPS 5 to 10%
Read more on VBO's here
Remove any possible lag content

Such as Mobs and other entities, snow, decaying leaves and more
you can find a whole list of things to remove here:

The last thing you could do is install a lag reducing tool like OptiFine
There are plenty tutorials online on how to do this.

i am sadly not using optifine and i dont have vbo's option. i only wanted to test the bees today, and then tick lag makes them feel like i have slow internet on an overloaded server. they dont move. LITERALLY just floating there, as well as other mobs. blocks come back after being mined. then switching to optifine for more options i did a couple of stuff in the settings and it did kind of fix it.... but on a flat world, no lag AND no LAG at all. kind of makes me rage tbh...
even with the lowest settings the tick lag still happens. trying this on a computer with a very expensive cpu on a computer cafe. it still happens.
i did solve it by using optifine and disabling and enabling certain options...

Settings> Videos> i did turn on vbos as said.
Enabled lazy chunk loading.
Graphics> fast
Clouds: off

less tick lag. but that doesn't mean it's totally gone. it's just reduced.

sorry for edit spam, my keyboard is kind of under the weather at the moment...

This same exact thing happened to me. I was mining & it took me like 5 tries before I could actually mine the block. It just kept on reappearing after I mined it.
how to fix this problem

go to game menu (esc button) & then press "options..."
press "video settings..." & turn smooth lighting: OFF.

Once you've done this, the game should look a lot uglier but it will not be laggy anymore. You might need to close the Minecraft window for it to actually get better. (laggy wise, not ugly wise).
